Preliminary views on WRC-15 agenda items and new agenda item Global Flight Tracking (As of February 2015)

Agenda item 1.1

to consider additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for International Mobile Telecommunications (IMT) and related regulatory provisions, to facilitate the development of terrestrial mobile broadband applications in accordance with Resolution 233 (WRC-12);

1Background

In accordance with Resolution 233 (WRC-12), additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for IMT and related regulatory provisions will be considered under WRC-15 agenda item 1.1. In this regard, ITU-R Joint Task Group 4-5-6-7 (JTG) conducts studies on frequency-related matters of IMT and other terrestrial mobile broadband applications as a responsible group for WRC-15 agenda item 1.1 with the help of other concerned groups.
This contribution provides preliminary views on this agenda item from Japan.

2Preliminary Views

1. To cope with rapidly increasing mobile traffic, taking into account the studies on spectrum requirement for IMT in ITU-R, sufficient bandwidths should be secured to meet future IMT spectrum demand.
2. Technical discussions are necessary in ITU-R in order to protect existing services when considering additional allocation to the mobile service and identification for IMT on a worldwide basis (or on a Regional basis, or by footnotes which contain a number of countries’ names, depending on circumstances).
3. Results of studies on suitable frequency ranges for IMT in ITU-R WP 5D include but are not limited to the frequency ranges 1 427.9-1462.9/1 475.9-1 510.9 MHz, 3 400-4 200 MHz and 4 400-4 900MHz.
4. Considering the studies in ITU-R, Japan supports that the 1 427.9-1 462.9/1 475.9-1 510.9 MHz, 3 400-4 200 MHz and 4 400-4 900 MHz bands are allocated to the mobile service on a primary basis and identified for IMT on a worldwide basis (or on a Regional basis, or by footnotes which contain a number of countries’ names, depending on circumstances).

Agenda item 1.2

to examine the results of ITU-R studies, in accordance with Resolution 232 (WRC-12), on the use of the frequency band 694-790 MHz by the mobile, except aeronautical mobile, service in Region 1 and take the appropriate measures;

1Background

In accordance with Resolution 232 (WRC-12), examination of the results of ITU-R studies on the use of the frequency band 694-790 MHz by the mobile, except aeronautical mobile, service in Region 1 and identification of additional frequency bands for IMT will be considered under WRC-15 Agenda item 1.2. In this regard, ITU-R Joint Task Group 4-5-6-7 (JTG) conducts coexisting studies on mobile service and other services as a responsible group for WRC-15 Agenda item 1.2 with the help of other concerned groups.
This contribution provides preliminary views on this agenda item from Japan.

2Preliminary Views

It is desirable that frequency allocation to the mobile, except aeronautical mobile, service on a primary basis in the band 694-790 MHz for Region 1 is confirmed and a channelling arrangement for this band is developed considering the possibility of harmonization with the APT Region.

Agenda item 1.3

to review and revise Resolution 646 (Rev.WRC-12) for broadband public protection and disaster relief (PPDR), in accordance with Resolution 648 (WRC-12);

1Background

Existing PPDR technology uses narrowband and is utilized for voice and low-speed data communications. At WRC-12, New Resolution 648 has been approved in order to study technical and operational problems with broadband PPDR as well as its development in the future, taking into account the improvement of broadband radiocommunications technology in recent years.

Resolution 648 resolves to revise Resolution 646 (Rev. WRC-12) in order to study broadband PPDR, and WRC-15 Agenda item 1.3 has been established to address these issues.

2Preliminary Views

Japan is promoting broadband systems for public use utilizing the 200 MHz band. For this reason, Japan will support Method B for the revision of the CPM text, which includes a description of a 200 MHz band PPDR system. Japan expects to promote adequate research giving due consider to any impact on existing services with respect to the addition of frequency bands for broadband PPDR.

Agenda item 1.4

to consider possible new allocation to the amateur service on a secondary basis within the band 5 250-5 450 kHz in accordance with Resolution 649 (WRC-12);

1Background

Based on the usefulness of amateur service in emergency situations, especially utilization as an alternative measure where networks have been damaged due to natural disasters, a proposal has been made to consider possible new allocations to the amateur service on a secondary basis in the 5 300 kHz band, and WRC-15 Agenda item 1.4 has been inserted to meet Resolution 649 (WRC-12).

2Preliminary Views

In Japan, the 5 250-5 450 kHz band is allocated and used for fixed and mobile services on a primary basis. For this reason, it is not appropriate to make new allocations to amateur service on a secondary basis until compatibility with existing services can be confirmed. If this band were to be allocated to amateur service, Japan would expect to apply appropriate restrictions to the operation of amateur stations in order to assure compatibility.

Agenda item 1.5

to consider the use of frequency bands allocated to the fixed-satellite service not subject to Appendices 30, 30A and 30B for the control and non-payload communications of unmanned aircraft systems (UAS) in non-segregated airspaces, in accordance with Resolution 153 (WRC-12);

1Background

Resolution 153 (WRC-12) resolves to consider the use of frequency bands allocated to the fixed-satellite service not subject to Appendices 30, 30A and 30B for the control and non-payload communications of unmanned aircraft systems in non-segregated airspaces.

A substantial increase in worldwide use of unmanned aircraft systems (UAS) is expected in the future. Seamless operation of unmanned aircraft (UA) with piloted aircraft is becoming essential for the further development of unmanned aircraft applications with diverse requirements in non-segregated airspace. For the safe operation of UA a reliable communication link is essential between the remote pilot and the UA in order to command and control the UA and to relay air traffic communication. Therefore, an eligible harmonic spectrum is required to meet this need.

In light of this demand and the capacity and networks of fixed satellite service (FSS) systems, the World Radiocommunication Conference 2012 (WRC-12) resolves to invite ITU-R to consider technical, regulatory, and operational conditions for UA command and non-payload communication (CNPC) links though space systems operating in the FSS.

At its meeting of Working Party 5B on October 2014, the Working Document toward Preliminary Draft New Report M.[UAS-FSS] was discussed and a conclusion was almost achieved. The document is planned to be completed at the next WP 5B meeting.

2Preliminary Views

Japan is of the view that sufficient studies should be conducted to prevent an adverse impact on the existing services.

Agenda item 1.6

to consider possible additional primary allocations;

• 1.6.1 
  to the fixed-satellite service (Earth-to-space and space-to-Earth) of 250 MHz in the range between 10 GHz and 17 GHz in Region 1
• 1.6.2 
  to the fixed-satellite service (Earth-to-space) of 250 MHz in Region 2 and 300 MHz in Region 3 within the range 13-17 GHz;

and review the regulatory provisions on the current allocations to the fixed-satellite service within each range, taking into account the results of ITU-R studies, in accordance with Resolutions 151 (WRC-12) and 152 (WRC-12), respectively;

1Background

The existing unplanned FSS bands in the 10-15 GHz range are used extensively for a myriad of applications such as very small aperture terminal (VSAT) services, video distribution, broadband networks, internet services, satellite news gathering, and backhaul links. Growth in demand for these applications has triggered a rapid rise in the demand for spectrum. Moreover, satellite traffic is typically symmetrical in a large variety of applications, i.e. similar amounts of Earth to space (uplink) and space-to-Earth (downlink) traffic are transmitted.

WRC-12 adopted WRC-15 agenda item 1.6 to consider additional primary allocations to the fixed satellite service (FSS) in the range 10-17 GHz in Region 1 (Earth-to-space and space-to-Earth) and in the range 13-17 GHz in Region 2 & 3 (space-to-Earth) and a review of regulatory provisions for existing FSS allocations, taking into account ITU-R studies in accordance with Resolution 151 (WRC-12) and 152 (WRC-12).

In this study period of the ITU-R, Working Party 4A has studied the issue of frequency sharing with the existing services in the frequency bands in question on a band-by-band basis as a responsible group for this agenda item. Annex 1 of this document summarizes the current conclusion of the band-by-band study with respect to Agenda Item 1.6.2 of WRC-15 as a reference.

2Preliminary Views

Japan is of the view that it would be beneficial to straighten out the difference between the bandwidth of the FSS uplink and that of the FSS downlink from the perspective of efficient use of the frequency spectrum/orbit resources. Therefore this Administration supports additional allocation and/or revision of regulatory provisions on current allocations to the FSS provided that the radiocommunication services to which the frequency band in question is currently allocated on a primary basis are adequately protected.

Therefore this Administration takes the following positions:

• - 
  not to oppose the allocation of 13.4-13.75 GHz band to the FSS (space-to-Earth) in Region 1 (Agenda Item 1.6.1)
• - 
  to support the modification of the existing FSS allocation to support FSS uplinks that are not limited to BSS feeder links in 14.5-14.8 GHz band in Region 2 and 3 (Agenda Item 1.6.2)
• - 
  not to oppose the allocation of 14.8-15.1 GHz band to the FSS (Earth-to space) in Region 2 and 3 (Agenda Item 1.6.2)

Agenda item 1.7

to review the use of the band 5 091-5 150 MHz by the fixed-satellite service (Earth-to-space) (limited to feeder links of the non-geostationary mobile-satellite systems in the mobile-satellite service) in accordance with Resolution 114 (Rev.WRC-12);

1Background

Resolution 114 (Rev. WRC-12) resolves to invite ITU-R to conduct studies about the technical and operational issues relating to sharing of the band 5 091-5 150 MHz between new systems of the aeronautical radionavigation service (ARNS) and the fixed satellite service (FSS) providing feeder links of the non-GSO systems in the mobile satellite service (MSS) (Earth-to-space). The Resolution 114 (Rev. WRC-12) also invites ICAO to supply technical and operational criteria suitable for sharing studies for new aeronautical systems.

ITU-R Working Party 4A (WP 4A) and Working Party 5B (WP 5B) are the responsible group and concerned group for this agenda item, respectively.

Previous studies have resulted in Recommendation ITU-R S.1342 which describes a method for determining coordination distances between international standard MLS stations operating in the band 5 030-5 091 MHz and FSS Earth stations in the adjacent band 5 091-5 150 MHz providing Earth-to-space feeder links for non-geostationary MSS systems.

Previous studies have resulted in the creation of Recommendation ITU-R M.1827 which provides the technical and operational requirements for stations of AM(R)S limited to surface applications at airports ensuring compatibility with FSS feeder link earth stations operating in the band 5 091-5 150 MHz.

ICAO indicated during this study cycle that it does not foresee or plan any new ARNS (non MLS) systems in the band 5 091-5 150 MHz. On this basis, no new studies in the band 5 030-5 091 MHz are required since Recommendation ITU-R S.1342 remains the technical reference for determining the need for coordination between the international standard MLS in the band 5 030-5 091 MHz and systems of the FSS providing Earth-to-space feeder links in the band 5 091-5 150 MHz.

At its meeting of February 2014, WP 4A proposed a single method to satisfy this agenda item. This method proposes that the use of the band 5 091-5 150 MHz by systems of the FSS providing Earth-to-space feeder links for non-GSO systems in the MSS be maintained as a primary allocation with suppression of the conditions on this allocation given in No. 5.444A of the radio regulations (RR); i.e. after 1 January 2016 no new assignments shall be made, and after 1 January 2018 the FSS will become secondary to the ARNS. To realize this method, WP 5B revised Recommendation ITU-R M.1827.

2Preliminary Views

Japan supports the single method to use the band 5 091-5 150 MHz for systems of the FSS providing feeder links for non-GSO systems in the MSS in the Earth-to-space direction with the suppression of the current limitation on RR No. 5.444A.

Agenda item 1.8

to review the provisions relating to Earth Stations located on board Vessels (ESVs), based on studies conducted in accordance with Resolution 909 (WRC 12);

1Background

As Resolution 902 (WRC-03) was approved by WRC-03, the technical background of this Resolution is summarized in Recommendation ITU-R SF.1650-1, etc.

In this study period of the ITU-R, Working Party 4A has studied this Agenda Item as the responsible group and developed a WD-PDNRep. (document 4A/591N26) and draft CPM text (document 4A/591N3). In these working documents, the following studies and methods to satisfy the agenda item are presented:

• - Method A 
  No change to the Radio Regulations
• - Method B 
  Increasing off-shore protection distances in the C band
• - Method C 
  Establishment of different protection distances for different maximum e.i.r.p. density levels, with shorter protection distances for e.i.r.p. density levels lower than those currently allowed by Resolution 902 (WRC-03)
• - Method D 
  Establishment of different protection distances for different maximum e.i.r.p. density levels for the increasing ESVs passes in the C & Ku bands
• - Method E 
  Review of the regulatory regime governing operation of ESVs

2Preliminary Views

Japan is of the view that adequate protection of the existing radiocommunication service (i.e. the FS) and prevention of imposing additional constraints on ESVs in the 5925-6425 MHz and 14.0-14.5 GHz frequency bands are imperative. Therefore this Administration supports Method A (NOC) in the draft CPM Report.

Agenda item 1.9.1

to consider, in accordance with Resolution 758 (WRC12), possible new allocations to the fixed-satellite service in the frequency bands 7 150-7 250 MHz (space-to-Earth) and 8 400-8 500 MHz (Earth-to-space), subject to appropriate sharing conditions;

Resolution 758 (WRC-12) – Allocation to the fixed-satellite service and the maritime-mobile satellite service in the 7/8 GHz range;

1Background

There is a worldwide allocation to the fixed-satellite service (FSS) in the frequency bands 7 250-7 750 MHz (space-to-Earth) and 7 900-8 400 MHz (Earth-to-space). Considering that some administrations have reported a shortfall of spectrum available for their current and future FSS applications, and the additional bandwidth requirements for data transmission on the next-generation satellites were estimated to be around a maximum 100 MHz, WRC-12 adopted Resolution 758 (WRC-12) to addresses the possibility of extending the existing bands for FSS to the bands 7 150-7 250 MHz (space-to-Earth) and 8 400-8 500 MHz (Earth-to-space) under WRC-15 Agenda item 1.9.1.

Currently, the band 7 150-7 235 MHz is allocated on a primary basis for fixed service (FS), mobile service (MS) and space research service (SRS) in the Earth-to-space direction while the band 7 235-7 250 MHz is allocated on a primary basis for FS and MS only. Similarly, the band

8 400-8 500 MHz is allocated on a primary basis for FS, MS (except aeronautical), and SRS (space-to-Earth).

ITU-R has been conducting technical and regulatory studies on the possible new allocations to the FSS in the frequency bands 7 150-7 250 MHz (space-to-Earth) and 8 400-8 500 MHz (Earth-to-space) in order to ensure compatibility with existing services, with a view to extending the current worldwide allocations to the FSS in the bands 7 250-7 750 MHz (space-to-Earth) and

7 900-8 400 MHz (Earth-to-space) in accordance with Resolution 758 (WRC-12).

The results of ITU-R studies of FSS sharing with terrestrial and other space services in the 7/8 GHz bands are contained in the preliminary draft new Report (PDNRep.) ITU-R S.[FSS 7/8 GHZ COMPATIBILITY].

It is necessary to note that WRC-15 Agenda item 1.11 invites the ITU-R to conduct compatibility studies between EESS (Earth-to-space) systems and existing services, with priority to the band 7 145-7 235 MHz, in order to complement telemetry operations of EESS (space-to-Earth) in the 8 025-8 400 MHz band in accordance with Resolution 650 (WRC12).

It is also noted that the sharing studies in ITU-R have identified certain regions around FSS GSO satellites in which interference from FSS GSO satellites could exceed the SRS protection criteria. Therefore, further work for deep space SRS spacecraft crossing such interference regions is needed before concluding these studies concerning SRS-deep space in the band 7 145-7 190 MHz.

The three methods are currently being contained in the draft CPM Report to satisfy this agenda item;

• Method A 
  proposes primary worldwide allocations of the bands 7 150-7 250 MHz in the space-to-Earth direction and 8 400-8 500 MHz in the Earth-to-space direction to the FSS.
• Method B 
  proposes the same primary worldwide allocations except the band 7 150-7 190 MHz. For Methods A and B, the use of these bands is limited to GSO FSS space stations, and existing services are protected through the introduction of additional technical and regulatory measures including operational measures under specific circumstances. Additionally, the FSS shall not claim protection from the SRS and the space operation service (SOS).
• Method C 
  proposes no change to the Radio Regulations.

2Preliminary Views

ITU-R studies for sharing and compatibility issues with existing services in co-frequency and adjacent frequency bands should be sufficiently conducted to protect the existing primary services.

Current technical studies in ITU-R concluded that, since the sharing between SRS (deep space) and FSS in the band 7 150 - 7 190 MHz is not feasible, operational measures between involved FSS and SRS systems are required. However, since studies for such required operational measures have not been initiated in ITU-R, the practicality of such operational measures is still uncertain. Therefore, Japan does not support the proposed new FSS allocation in the band 7 150 - 7 190 MHz, in order to ensure protection of the SRS (deep space) in the band 7 145 - 7 190 MHz.

Japan supports that ITU-R further conducts technical and regulatory studies in order to ensure the protection of SRS in the band 7 190 – 7 235 MHz.

Agenda item 1.9.2

to consider, in accordance with Resolution 758 (WRC-12): the possibility of allocating the bands 7 375-7 750 MHz and 8 025-8 400 MHz to the maritime-mobile satellite service and additional regulatory measures, depending on the results of appropriate studies;

Resolution 758 (WRC-12) - Allocation to the fixed-satellite service and the maritime mobile-satellite service in the 7/8 GHz range;

1Background

Resolution 758 (WRC-12) resolves to invite ITU-R "to conduct technical and regulatory studies on the possibility of allocating the bands 7 375-7 750 MHz (space-to-Earth) and 8 025-8 400 MHz (Earth-to-space), or parts thereof, to the maritime-mobile satellite service, while ensuring compatibility with existing services".

Currently allocated services in the frequency bands 7 375-7 750 MHz and 8 025-8 400 MHz are as follows;

The 7 375-7 750 MHz band is allocated to the fixed, fixed-satellite (space-to-Earth) and mobile services. The 7 450-7 550 MHz band is also allocated to the meteorological-satellite service (space-to-Earth).

The 8 025-8 400 MHz band is allocated to the Earth exploration-satellite (space-to-Earth), fixed, fixed-satellite (Earth-to-space) and mobile services. In addition, the band 8 175-8 215 MHz is allocated to the meteorological-satellite service (Earth-to-space).

The results of ITU-R studies of MMSS sharing with terrestrial and other space services in the 7/8 GHz bands are contained in the preliminary draft new Report (PDNRep.) ITU-R S.[MMSS 7/8 GHZ SHARING].

In accordance with those studies, separation distances in the order of several hundred kilometres are required to protect the earth stations in the Earth exploration-satellite service (EESS) and also fixed stations from interference. Studies also show that space research service (SRS) deep space earth stations operating in adjacent bands would have to be protected through combination of unwanted emission limits and/or separation distance. Moreover, there is uncertainty on how to apply RR Nos. 9.17, 9.17A and 9.18 for MMSS earth stations

The two methods are currently being contained in the draft CPM Report to satisfy this agenda item;

• Method A 
  - There would be no allocation to the MMSS within the 7 375-7 750 MHz and 8 025-8 400 MHz bands and therefore no change to the RR.
• Method B 
  - The 7 375-7 750 MHz and 8 025-8 400 MHz bands would be allocated to the MMSS under the following conditions.

2Preliminary Views

ITU-R studies for sharing and compatibility issues with existing services in co-frequency and adjacent frequency bands should be sufficiently conducted to protect the existing primary services.

In order to discuss the proposed MSS allocations, sufficient studies for practical and implementable regulatory provisions should be conducted with a view to ensuring the protection of the existing services. However, since current ITU-R studies are not matured yet, Japan supports Method A (No Change).

Agenda item 1.10

to consider spectrum requirements and possible additional spectrum allocations for the mobile-satellite service in the Earth-to-space and space-to-Earth directions, including the satellite component for broadband applications, including International Mobile Telecommunications (IMT), within the frequency range from 22 GHz to 26 GHz, in accordance with Resolution 234 (WRC-12);

1Background

Resolution 234 (WRC-12) resolves to invite ITU-R: to complete, for WRC-15, sharing and compatibility studies towards additional allocations to the mobile-satellite service in the Earth-to-space and space-to-Earth directions, within portions of the bands between 22 GHz and 26 GHz, while ensuring protection of existing services within these bands as well as taking into account No. 5.340 and No. 5.149.

According to the Radio Regulations, the band between 22 GHz and 26 GHz is allocated to the following services: Radio Astronomy service, Earth Exploration-Satellite service, Space Research service, Inter-Satellite service, Fixed-Satellite service, Amateur-Satellite service, Radiolocation-Satellite service, Standard Frequency and Time Signal-Satellite service, Amateur Service, Radiolocation Service, Radionavigation Service, Fixed Service and Mobile Service.

Though the lack of spectrum available for MSS in the 1-6 GHz band and 4-6GHz is indicated in Reports ITU-R M.2077 and M.2218 respectively, the ITU-R has not yet estimated the total requirements for MSS in the 22-26 GHz frequency range.

Though studies for frequency sharing and criteria for compatibility between new allocation to MSS and existing services are also conducted in the ITU-R, not all services within the 22-26 GHz bands have been studied for sharing with new MSS systems.

The following methods are currently contained in the Draft CPM Report:

• Method A : 
  There would be no allocation to the MSS within the 22-26 GHz band and, therefore, no change to the RR, and the requirements can be met in other allocations.
• Method B : 
  To allocate the frequency bands 23.15-23.55 GHz (space-to-Earth) and 25.25-25.5 GHz (Earth-to-space) to the MSS on the following conditions:

  • - 
    MSS allocation shall be limited only to geostationary systems;
  • - 
    Application of pfd limits (see Table 4.2/1.10/4.3-1) for MSS transmitting space stations in the frequency band 23.15-23.55 GHz;
  • - 
    Application of e.i.r.p. limits (see Table 4.2/1.10/4.4-1) for MSS transmitting space stations in the frequency band 23.15-23.55 GHz;
  • - 
    Coordination of MSS stations with ISS in accordance with RR No. 9.7 in the frequency bands 23.15-23.55 GHz (space-to-Earth) and 25.25-25.5 GHz (Earth-to-space);
  • - 
    Coordination of MSS transmitting earth stations with FS and MS receiving stations under RR No. 9.17 in the frequency band 25.25-25.5 GHz.
• Method C : 
  Provide allocations to the MSS in the 22-26 GHz range.
• Method C1 : 
  Allocations for the MSS in the space-to-Earth direction.

  Option C1a: To allocate the frequency band 24.25-24.55 GHz for the MSS (space-to-Earth) with the following conditions:

  • - 
    MSS allocation shall be limited only to geostationary systems;
  • - 
    Application of pfd limits (see Table 4.2/1.10/4.3-2) for MSS transmitting space stations in the frequency band 24.25-24.55 GHz;
  • - 
    Coordination of MSS space stations under RR No. 9.7.

  or

  Option C1b: To allocate the frequency band 22.65-22.95 GHz for the MSS (space-to-Earth) with the following conditions:

  • - 
    MSS allocation shall be limited only to geostationary systems;
  • - 
    Application of pfd limits (see Table 4.2/1.10/4.3-2) for transmitting space stations in the frequency band 22.65-22.95 GHz;
  • - 
    Coordination of MSS stations with the ISS in accordance with RR No. 9.7 in the frequency band 22.65-22.95 GHz (space-to-Earth).
• Method C2 : 
  Allocations for the MSS in the Earth-to-space direction.

  Option C2a: To allocate the frequency band 24.25-24.55 GHz for the MSS (Earth-to-space) with the following conditions:

  • - 
    MSS allocation shall be limited only to geostationary systems;
  • - 
    Coordination of MSS space stations under RR No. 9.7;
  • - 
    Apply RR No. 9.17 to ensure protection of the terrestrial services.

  or

  Option C2b: To allocate the frequency band 25.25-25.5 GHz for the MSS (Earth-to-space) with the following conditions:

  • - 
    MSS allocation shall be limited only to geostationary systems;
  • - 
    Coordination with the ISS under RR No. 9.7;
  • - 
    Apply RR No. 9.17 to ensure protection of the terrestrial services.

2Preliminary Views

ITU-R studies for sharing and compatibility issues with existing services in co-frequency and adjacent frequency bands should be sufficiently conducted to protect the existing primary services.

Japan does not support the new MSS allocations in the band 22 - 26 GHz since ITU-R studies provide no positive sharing/compatibility result with the existing services.

Unless studies ensuring the protection of the existing services are provided, Japan does not support discussing new MSS allocation in the band 22-26 GHz.

Agenda item 1.11

to consider a primary allocation for the Earth exploration-satellite service (Earth-to-space) in the 7-8 GHz range, in accordance with Resolution 650 [COM6/17] (WRC-12);

Resolution 650 (WRC-12 ):

to invite ITU-R to conduct a study of spectrum requirements in the 7 8 GHz range for EESS (Earth-to-space) telecommand operations in order to complement telemetry operations of EESS (space-to-Earth) in the 8 025-8 400 MHz band, and to conduct compatibility studies between EESS (Earth-to-space) systems and existing services

1Background

Resolution 650 (WRC-12) calls for study of the spectrum requirements and compatibility studies in the 7-8 GHz range for EESS (Earth-to-space) telecommand operations in order to complement telemetry operations of the EESS (space-to-Earth) in the 8 025-8 400 MHz band.

An allocation to the EESS (Earth-to-space) is needed to provide an uplink to complement the existing downlink primary allocation to the EESS (space-to-Earth) in the 8 025-8 400 MHz band. At present, the only existing uplink available to the EESS is in the increasingly congested 2 025-2 110 MHz band, complementing the downlink allocation at 2 200-2 290 MHz.

Sharing studies have been addressed in Working Party 7B (WP 7B) as the responsible group for this WRC-15 Agenda item. Sharing studies between stations of the EESS (Earth-to-space) and the SRS, FS, MS and SOS in various portions of the 7-8 GHz band are presented in the resultant ITU-R Reports SA.2272, SA.2275 and SA.2309.

These studies show that sharing would be feasible in the band 7 190-7 250 MHz, which would satisfy the EESS requirements identified.

In the draft CPM Report two methods, Method A and B, have been proposed to satisfy this agenda item, and a third method C, with a proposal of no change to the Radio Regulations, was also included. However, Method C is not based on any ITU-R study results.

1.1 Methods to satisfy the agenda item

1.1.1 Method A

This method proposes to add a global primary allocation to the EESS in the band 7 190-7 250 MHz in the Table of Frequency Allocations in RR Article 5.

Additionally, Table 7b in RR Appendix 7 is modified to include the EESS allocation, Table 21-2 in RR Article 21 is modified to extend the range 7 145-7 235 MHz to 7 145-7 250 MHz, and Table 21-3 in RR Article 21 is modified to extend the range 7 190-7 235 MHz to 7 190-7 250 MHz.

Resolution 650 (WRC-12) would be consequentially suppressed.

With respect to additional regulatory provisions, three options are considered:

Option 1

• - 
  Addition of a new footnote in the Table of Frequency Allocations in RR Article 5 to limit the use of the band 7 190-7 250 to non-geostationary EESS satellite systems.

Option 2

• - 
  Modification of RR footnote No. 5.460 in order to:

  • - 
    indicate that geostationary EESS satellite systems shall not claim protection from existing and future stations of the fixed and mobile services, and that No. 5.43A does not apply.

Option 3

• - 
  Modification of RR footnote No. 5.460 in the Table of Frequency Allocation in RR Article 5 in order to:

  • - 
    indicate that geostationary EESS satellite systems shall not claim protection from existing and future stations of the fixed and mobile services, and that No. 5.43A does not apply.
  • - 
    restrict the usage of the band 7 190-7 250 MHz to the operation of the EESS spacecraft, because the aim for the Resolution 650 (WRC-12) is to obtain a new allocation in the band 7-8 GHz for the TT&C operations.

1.1.2 Method B

This method proposes to add a global primary allocation to the EESS in the band 7 190-7 250 MHz in the Table of Frequency Allocations in RR Article 5 and to include a provision with regard to this allocation under which:

• - 
  such allocation is limited to non-geostationary satellite systems;
• - 
  for operation of EESS in the frequency band 7 190-7 235 MHz coordination shall be applied with regard to SOS under RR No. 9.11A;
• - 
  space stations in the EESS (Earth-to-space) shall not claim protection from SRS earth stations in the frequency band 7 190-7 235 MHz;
• - 
  space stations in the EESS (Earth-to-space) shall not claim protection from the existing and future stations in the fixed and mobile services in the frequency band 7 235 7 250 MHz.

Additionally, Table 7b in RR Appendix 7 is modified to include the EESS allocation, and Table 21-3 in RR Article 21 is modified to extend the range 7 190-7 235 MHz to 7 190-7 250 MHz.

Note: Table 21-2 in RR Article 21 is not modified with this Method B.
Resolution 650 (WRC-12) would be consequentially suppressed.

1.1.3 Method C

No change in the RR Article 5 and suppression of Resolution 650 (WRC-12).

There would be no allocation to the EESS (Earth-to-space) in the band 7 190-7 250 MHz.

2Preliminary Views

Japan supports the current ITU-R studies providing positive results on the sharing between existing primary services and proposed EESS (Earth to space) in the band 7 190-7 250 MHz. In light of this, Japan supports primary allocation to EESS (Earth to space) in the band 7 190-7 235 MHz. In accordance with the status of the current ITU-R studies, the new allocation to EESS (Earth to space) should be limited to Non-GSO EESS.

Agenda item 1.12

to consider an extension of the current worldwide allocation to the Earth exploration-satellite (active) service in the frequency band 9 300-9 900 MHz by up to 600 MHz within the frequency bands 8 700-9 300 MHz and/or 9 900-10 500 MHz, in accordance with Resolution 651 (WRC-12);

1Background

WRC-15 Agenda item 1.12 resolves for Administrations to consider possible additional allocations to the Earth exploration-satellite (active) service within the frequency bands 8 700-9 300 MHz and/or 9 900-10 500 MHz, in accordance with Resolution 651 (WRC-12). The Resolution invites ITU-R to conduct and complete, in time for WRC-15, compatibility studies addressing EESS (active) and existing services in the frequency bands 8 700-9 300 MHz and 9 900-10 500 MHz, and in the adjacent bands.

It is noted that the APT Common Proposal to WRC-12 supported consideration of an extension of the current allocation to EESS (active) within the frequency range 8 700-10 500 MHz on a secondary basis. However the agenda approved by the Conference did not mention secondary or primary allocation in the agenda and left the matter to the outcome of studies which could result in a primary and/or secondary allocation in accordance with Resolution 651 (WRC-12).

As indicated in Annex 8 of ITU BR Administrative Circular letter CA/201 of 19 March 2012 "Results of the first session of the Conference Preparatory Meeting for WRC-15", CPM15-1 identified Working Party 7C as the responsible Working Party to study the topic under WRC-15 Agenda item 1.12. It also identified WPs 5A, 5B, 5C, 7B, 7D as contributing groups regarding the incumbent radio services.

The overall sharing conditions for protection of other radio services in relevant administrations from emissions of EESS (active) services in the band 9300-9900 MHz are found in footnotes Nos. 5.475A, 5.476A, 5.477, 5.478, 5.478A, and No. 5.478B.

Sharing studies were performed for all incumbent services. The results of sharing studies with the RDS are contained in Report ITU-R RS.2313. The results of sharing studies with the FS, MS, amateur service and amateur-satellite service are contained in Report ITU-R RS.2314. The results of compatibility studies related to unwanted emissions into the SRS, RAS, EESS (passive), and SRS (passive) are contained in Report ITU-R RS.2308.

The following methods to satisfy this agenda item have been developed in the draft CPM Report.

• Method A 
  – Primary EESS (active) allocation in the band 9 900-10 500 MHz.

  • Method A1 
    – Add primary allocation to EESS (active) in the band 9 900 10 500 MHz. This method would impose that the EESS (active) shall not cause harmful interference to, nor claim protection from the radiolocation service allocated in the band 9 900-10 500 MHz. In addition, the extension band shall only be used by EESS (active) systems requiring a bandwidth greater than 600 MHz that cannot be accommodated in the frequency band 9 300-9 900 MHz. The protection of radio astronomy service in the band 10.6-10.7 GHz will be ensured through Recommendation incorporated by reference in the Radio Regulations.
  • Method A2 
    – Make a primary EESS (active) allocation in the band 9 900-10 500 MHz subject to inclusion of technical and regulatory constraints into Radio Regulations to ensure protection for radiolocation and fixed services having allocations in this frequency band. The protection of fixed service (FS) is to be ensured through a footnote in the Radio Regulations with a pfd-limit. The protection of radio astronomy service in the band 10.6-10.7 GHz will be ensured through Recommendation incorporated by reference in the Radio Regulations.

  In addition, the extension band shall only be used by EESS (active) systems requiring a bandwidth greater than 600 MHz that cannot be accommodated in the frequency band 9 300-9 900 MHz.

• Method B 
  – Primary EESS (active) allocation in the bands 9 200-9 300 MHz and 9 900-10 400 MHz

  Add primary allocation to EESS (active) in the bands 9 200-9 300 MHz and 9 900 10 400 MHz. This method would impose that the EESS (active) shall not cause harmful interference to, nor claim protection from, the radio determination services allocated in the bands 9 200-9 300 MHz and 9 900-10 400 MHz. In addition, the extension band shall only be used by EESS (active) systems requiring a bandwidth greater than 600 MHz that cannot be accommodated in the frequency band 9 300-9 900 MHz. The protection of radio astronomy service in the band 10.6-10.7 GHz will be ensured through Recommendation incorporated by reference in the Radio Regulations.

2Preliminary Views

Japan supports the ITU-R studies that have examined the feasibility of sharing and compatibility between the EESS (active) in the bands proposed to be extended and existing primary services. In light of the result of ITU-R studies, Japan also supports the extension of current EESS (active) allocation with additional continuous 600 MHz as a primary basis as studied with the following consideration and conditions:

• taking into account the safety of life aspects of the aeronautical radionavigation services in the bands 9 000 – 9 200 MHz and 9 300 – 9 500 MHz;
• protection of the maritime radionavigation services in the band 9 200 – 9 500 MHz;
• protection of the SRS (deep space) operating in the band 8 400 - 8 450 MHz and the RAS/EESS (passive) operating in the band 10.6 - 10.7 GHz through the implementation of mitigation techniques contained in appropriate ITU-R recommendations;
• protection of the MS and FS (BAS) in 10 GHz band through appropriate sharing conditions such as pfd limit to EESS(active).

Agenda item 1.13

to review No. 5.268 with a view to examining the possibility for increasing the 5 km distance limitation and allowing space research service (space-to-space) use for proximity operations by space vehicles communicating with an orbiting manned space vehicle, in accordance with Resolution 652 (WRC-12);

Resolution 652 (WRC-12):

Use of the band 410-420 MHz by the space research service (space-to-space)

1Background

WARC-92 allocated the band 410-420 MHz to the space research service on a secondary basis. The 5 km limit was agreed during WARC-92 when the envisioned use of the band was limited to free floating astronauts working in the rear vicinity of a manned space vehicle. The addition of power flux density (pfd) limits by WRC-97 provided primary allocation for SRS (space-to-space) uses as specified in RR No. 5.268 while ensuring the protection of systems operating in the fixed and mobile services.

Resolution 652(WRC-12) calls for studies between SRS (space-to-space) systems communicating in proximity with orbiting manned space vehicles and systems operating in the fixed and mobile (except aeronautical mobile) services in the band 410-420 MHz. It invites WRC-15 to review RR No. 5.268 with a view to examining the possible removal or relaxation of the 5 km distance limitation without modifying the current pfd limits and allowing space research service (space-to-space) use for proximity operations by space vehicles communicating with an orbiting manned space vehicle. Further, Resolution 652 (WRC-12) recognizing c, states that "power flux-density (pfd) limits contained in RR No. 5.268 ensure the protection of terrestrial stations operating in the fixed and mobile services independent of the distance from, or the source of, space-to-space communications in the SRS".

Sharing between stations of the SRS (space-to-space) and fixed and mobile services in the band 410-420 MHz has been studied by ITU-R Working Party 7B. These studies found that the protection criteria specified in RR No. 5.268 can be met without a distance limitation on SRS proximity operations – refer Report ITU-R SA.2271, titled "Sharing conditions between space research service proximity operations links and fixed and mobile service links in the 410-420 MHz band".

The single Method in the draft CPM text is as follows:

"The proposed method is to modify RR No. 5.268 to remove the 5 km distance limitation and not solely limit the use of the band for extra-vehicular activities. Also Resolution 652 (WRC-12) should be consequentially suppressed."

RESOLUTION 652 (WRC-12)

Use of the band 410-420 MHz by the space research service (space-to-space)

2Preliminary Views

Japan supports the ITU-R studies that have examined adequate protection of the fixed and mobile services by the pfd limits at the surface of the Earth contained in RR No. 5.268 without the 5 km distance limitation. Thus Japan also supports the removal of the distance restriction contained in RR No. 5.268 and the limitation to extra vehicular activities while keeping the pfd limits unchanged.

Agenda item 1.14

to consider the feasibility of achieving a continuous reference time-scale, whether by the modification of coordinated universal time (UTC) or some other method, and take appropriate action, in accordance with Resolution 653 (WRC-12);

1Background

RA-12 considered the draft revision of Recommendation ITU-R TF.460-6 which proposed the suppression of leap seconds adjustments to UTC. At RA-12 there was a portion of administrations in favour of the draft revision of the Recommendation and a portion opposing it. However, there was a third group of administrations that indicated they needed more time and information to form an opinion. As a result, RA-12 decided to return the draft revision to SG 7 for further study of other technical options in addition to those already considered in the preparation of the draft revision.

Further, the Assembly decided that this issue should be addressed in the RA-12 Report for World Radiocommunication Conference 2012 (WRC-12) to consider the possibility of developing a new WRC-15 Agenda item.

ITU-R WP7A is the responsible group for this agenda item. Japan has been contributing actively to research within ITU-R WP7A.

A Draft CPM text was agreed at WP7A meeting in May 2014, and the following Methods are proposed in the Draft CPM text.

1. Method A1:

   A continuous reference time-scale is feasible and can be achieved by stopping the insertion of leap seconds in UTC. To allow for an adequate period of time for those legacy systems reliant on the use of leap seconds to adapt to the change in UTC, the suppression of leap seconds adjustments to UTC will be effective no less than five years after the date of entry into force of the Final Acts of the WRC-15.

   For applications requiring knowledge of UT1 the difference between UT1 and UTC will continue to be provided by IERS with a much higher precision than that available from present broadcast UTC.

   The name of UTC will be retained.

2. Method A2: 
   This method is similar to Method A1 but it is proposed to change the name of UTC
3. Method B: 
   Retain UTC as currently defined and introduce a continuous reference atomic time-scale based on TAI with an offset to be broadcast on an equal basis.
4. Method C1: 
   No change in definition of UTC specified in Recommendation ITU R TF.460-6, which will remain the only time-scale which is broadcast in order to avoid any confusion. Under this method, Recommendation ITU-R TF.460-6 would be amended to make clear that use of TAI is an acceptable alternative for those requiring a continuous time-scale and that it can be derived from UTC using a difference figure which is also broadcast.
5. Method C2: 
   This method is similar to Method C1 except for Recommendation ITU-R TF.460-6 which would be amended to include additional definitions, corrections and/or materials with respect to the feasibility of using continuous system time-scales for radio communication systems.

2Preliminary Views

Japan supports the introduction of a new continuous reference time-scale by stopping the insertion of leap seconds in UTC.

Japan supports the name of UTC being retained after the introduction of the new continuous reference time-scale.

Agenda item 1.15

To consider spectrum demands for on-board communication stations in the maritime mobile service in accordance with Resolution 358 (WRC-12);

1Background

Resolution 358 (WRC-12) invites WRC-15 to consider, based on the results of ITU-R studies, the need to possibly identify additional UHF channels within the bands already allocated to the maritime mobile service for on-board communication stations; it also invites ITU-R to conduct, in time for WRC-15, studies to determine the spectrum requirements and potential frequency bands for on-board communication stations, taking into account the protection of services to which the frequency band is currently allocated.

Some UHF frequencies, in frequency range 450-470 MHz, are currently identified in

the Radio Regulations for on-board communication stations. Fixed and mobile services are allocated in frequency range 450-470 MHz on a primary basis.

There are two footnotes in the Radio Regulations Article 5 related to the use of UHF on-board communication frequencies:

• RR No. 5.287

  In the maritime mobile service, the frequencies 457.525 MHz, 457.550 MHz, 457.575 MHz, 467.525 MHz, 467.550 MHz and 467.575 MHz may be used by on-board communication stations. Where needed, equipment designed for 12.5 kHz channel spacing using also the additional frequencies 457.5375 MHz, 457.5625 MHz, 467.5375 MHz and 467.5625 MHz may be introduced for on-board communications. The use of these frequencies in territorial waters may be subject to the national regulations of the administration concerned. The characteristics of the equipment used shall conform to those specified in Recommendation ITU-R M.1174-2.

• RR No. 5.288

  In the territorial waters of the US and the Philippines, the preferred frequencies for use by on-board communication stations shall be 457.525 MHz, 457.550 MHz, 457.575 MHz and 457.600 MHz paired, respectively, with 467.750 MHz, 467.775 MHz, 467.800 MHz, and 467.825 MHz. The characteristics of the equipment used shall conform to those specified in Recommendation ITU-R M.1174-2.

The use of UHF frequencies for on-board communications is considered very important, without these, critical functions of the ship in restricted waters could not effectively take place. These functions include anchoring, berthing, control of fire-fighting/damage control parties, security patrols, terrorism threats etc., those communications are intended to be used for internal on board a ship, or between a ship and its lifeboats and life-rafts during lifeboat drills or operations, or for communication within a group of vessels being towed or pushed, as well as for line handling and mooring instructions. Whilst these are of significant concern to those operating the ship the consequences of failure affect not only the seafarer but have significant implications for the immediate environment the ship is operating in.

ITU-R Working Party 5B discussed methods at its 13th meeting in May 2014 concerning Agenda item 1.15 and the number of methods has been reduced to one. This method is described in the draft CPM report which supports analogue equipment using 25 kHz and 12.5 kHz channel spacing, and digital equipment using 12.5 kHz and 6.25 kHz channel spacing. The method also proposes not to identify new frequencies for on-board communications in UHF other than those indicated in RR. No. 5.287. Proposed amendments to provision RR No. 5.287 are as follows:

MOD

5.287 Use of the frequency bands 457.5125-457.5875 MHz and 467.5125-467.5875 MHz by In the maritime mobile service, is limited to the frequencies 457.525 MHz, 457.550 MHz, 457.575 MHz, 467.525 MHz, 467.550 MHz and 467.575 MHz may be used by on-board communication stations. Where needed, equipment designed for 12.5 kHz channel spacing using also the additional frequencies 457.5375 MHz, 457.5625 MHz, 467.5375 MHz and 467.5625 MHz may be introduced for on-board communications. The use of these frequencies in territorial waters may be subject to the national regulations of the administration concerned. The characteristics of the equipment and the channelling used arrangement shall be in conformity with to those specified in Recommendation ITU-R M.1174-23. The use of these frequency bands in territorial waters may also be subject to the national regulations of the administration concerned.

During the APG 15-3 meeting held in Brisbane, Australia in June 2014, the Drafting Group on Agenda item 1.15 agreed to develop an APT Preliminary View (Document: APG15-3/OUT-29) based on several input contributions submitted by administrations in APT region.

The draft revision of Recommendation ITU-R M.1174-2 is agreed at ITU-R SG 5 meeting in November 2014.

2Preliminary Views

Japan supports the single Method to address this Agenda item in the draft CPM report.

Agenda item 1.16

To consider regulatory provisions and spectrum allocations to enable possible new Automatic Identification System (AIS) technology applications and possible new applications to improve maritime Radiocommunication in accordance with Resolution 360 (WRC-12);

1Background

Resolution 360 (WRC-12) resolves to invite WRC-15

1. to consider, based on the results of ITU-R studies, modifications to the Radio Regulations (RR), including possible spectrum allocations, to enable new AIS terrestrial and satellite applications, with ensuring that these applications will not degrade the current AIS operations and other existing services;
2. to consider, based on the results of ITU-R studies, additional or new applications for maritime radiocommunication within existing maritime mobile and mobile-satellite service allocations, and if necessary to take appropriate regulatory measures.

1.1 Automatic Identification System

The AIS is a proven maritime data system, with a large number of ships equipped and a supporting terrestrial and satellite infrastructure established. The AIS is designed to assist safety of navigation.

AIS is used in the ship movement service for safety of navigation, it enables the identification of stations using this system, and provides information about a ship and its cargo. It provides a means for ships to exchange ship data, including identification, position, course and speed, with other nearby ships and coast stations.

AIS has the capability for data exchange by application-specific messages (ASM) for complementary information. The decision of WRC-12 to assign new channels of the RR Appendix 18 to digital communication makes the implementation and use of new digital communication means possible. The establishment of the maritime AIS, the VHF data exchange and certain satellite communication components on these new frequencies offers potential enhancements to VHF maritime safety communications on a global basis to satisfy the increasing need for maritime radiocommunication for enhanced maritime safety.

1.2 AIS VHF Data Link Loading

AIS VDL loading remains an issue to an increasing degree in many parts of the world due to the proliferation of AIS applications, message types, services and equipment types, plus the unanticipated increase in user volume.

Noting that WRC-12 has provided four candidate channels from the Appendix 18 on an experimental basis, to protect the integrity of the AIS VDL, it is considered beneficial to move ASM to two of these channels.

An increasing number of ASM will reduce the available time slots for the intended AIS messages. With increasing demand for maritime VHF data communications, AIS will become more heavily used, which will lead to an overloading of the existing AIS1 and AIS2 channels.

So far, some administrations reported that the AIS VDL loading in high traffic areas is nearing the critical limiting factor of 50%, as noted in International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) Recommendation A-124 Appendix 18 "VDL Loading Management". The new Report ITU-R M.2287 indicates the necessity of additional channels for the new applications using AIS technology.

1.3 VHF Data Exchange concept

The main activity relating to resolves 1 and resolves 2 in Resolution 360 (WRC-12) relates to a new concept called the VHF Data Exchange System (VDES) proposed by the IALA. Initially proposed as a terrestrial system, with a possible satellite broadcast capability (space-to-Earth) and called VHF Data Exchange (VDE), the current proposal includes transmission capability from ships (and other stations) to satellites (Earth-to-space) on certain VHF Appendix 18 channels, through VDES. The satellites could be in low Earth orbits and/or medium Earth orbits. It is important to note that existing channels AIS 1 and AIS 2, and channels 75 and 76 as used for the transmission of Message 27 (long-range AIS broadcast message), are all included in the VDES plan, and that AIS itself will play a crucial role, as will the Global Navigation Satellite System (GNSS).

The VDES concept addresses functions of VDE, ASM and the AIS in the VHF maritime mobile band.

The AIS 1 and AIS 2 (simplex channels) are intended to be preserved for their original purpose of safety of navigation, position reporting, and identification, in both the ship-to-ship and ship-to-shore and shore-to-ship directions.

1.4 Methods to Satisfy WRC-15 Agenda item 1.16

The following methods are described in the draft CPM report to satisfy this Agenda item:

1. Issue A 
   – Application specific message designation

   • Method A1 
     – Channels 27 and 28 of RR Appendix 18 will be split into four simplex channels, channels 1027, 1028, 2027 and 2028. Channels 2027 and 2028 will be identified for the ASM application. To prevent blocking of the reception of the channels AIS1, AIS 2, 2027 and 2028, transmission from ship on channels 2078, 2019, 2079 and 2020 will not be permitted. This will be achieved through a transitional period and an effective implementation date.
   • Method A2 
     – RR Appendix 18 simplex channels 87 and 88 will be assigned for ASM applications with an effective date.
     To prevent the potential blocking of the reception of the channels AIS1, AIS2 appropriate regulatory measures to restrict power limit for the transmission from ship on channels 2078, 2079, 2019, 2020 should be applied.
2. Issue B 
   – New applications for maritime radiocommunication – terrestrial component

   • Method B1 
     – In order to introduce the terrestrial component of the VDES, it is proposed to identify the duplex channels 24, 84, 25 and 85 of RR Appendix 18 for this purpose. It is further proposed that the merging of these channels will permit a better data rate for the VDE terrestrial component. This is achieved through a new Note (AAA) in the RR Appendix 18.
   • Method B2 
     – Channels 24, 84, 25, 85, 26 and 86 in RR Appendix 18 could be used for global harmonized VDE testing and experiments, including terrestrial component and satellite component.
3. Issue C 
   – New application for maritime radiocommunication – satellite component

   • Method C1 
     – The Method proposes a new secondary allocation for the maritime mobile-satellite service (Earth to-space) for frequency band 161.9375-161.9625 MHz (channel 2027) and frequency band 161.9875-162.0125 MHz (channel 2028) for improved ASM communications capacity and coverage.
     The Method proposes a new secondary allocation for the maritime mobile-satellite service (Earth to-space) for frequency band 157.1875-157.3375 MHz (channels 1024, 1084, 1025, 1085, 1026 and 1086).
     The Method proposes a new secondary allocation for the maritime mobile-satellite service (space to-Earth) for frequency band 161.7875-161.9375 MHz (channels 2024, 2084, 2025, 2085, 2026 and 2086), for improved VDE communications capacity and coverage.
     Coordination of VDE space stations of the MMSS (space-to-Earth) with respect to terrestrial services is described in modification of RR Appendix 5, proposing a pfd mask.
     The Method proposes to modify provision RR No. 5.208B in order to ensure the protection of the RAS in the nearest frequency band.
     In order to protect the RAS, Annex 1 to Resolution 739 (Rev.WRC-07) would be revised to include MMSS in the frequency band 161.7875-161.9375 MHz.
     The Method proposes to use an ITU-R Recommendation describing the concept and characteristics of VDES.
   • Method C2 
     – It is proposed to use the frequency band 148 150 MHz (Earth-to-space) for the purpose of the VDES satellite uplink (improvement of VDE communications capacity and coverage, ASM communications capacity and coverage) as the frequency band already allocated for MSS.
     It is proposed to use the frequency band 137-138 MHz (space-to-Earth) for the purpose of the VDES satellite downlink as the band already is allocated for MSS.
     These frequency bands are restricted to NGSO systems in accordance with provisions of RR No. 5.209.
     Furthermore, for the frequency band 137-138 MHz, Resolution 739 (Rev. WRC-07) applies (see RR No. 5.208B).
     No additional allocations and RR changes are required to MSS for this method.
4. Issue D 
   – VDES regional solution

   • Method D 
     • –

Japan supports Methods A1, B1, C1 and D.

Agenda item 1.17

to consider possible spectrum requirements and regulatory actions, including appropriate aeronautical allocations, to support wireless avionics intra-communications (WAIC), in accordance with Resolution 423 (WRC-12);

1Background

Resolution 423 (WRC-12) resolves to invite ITU-R to conduct studies to determine the spectrum requirements needed to support Wireless Avionics Intra-Communications (WAIC) systems, and to conduct sharing and compatibility studies based on the results of studies about spectrum requirements to determine appropriate frequency bands and regulatory actions. According to Resolution 423 (WRC-12), the frequency bands to be initially reviewed are limited to those frequency bands containing the aeronautical mobile (route), and aeronautical mobile and aeronautical radionavigation services below 15.7 GHz. In addition, frequency bands above 15.7 GHz can be studied if spectrum requirements cannot be met in the frequency bands allocated to the aeronautical services below 15.7 GHz.

ITU-R Working Party 5B (WP 5B) is the responsible group for this agenda item.

WAIC systems considered at the meetings of WP 5B are described in draft new Report ITU-R M.[WAIC_CHAR_SPEC]. WAIC systems utilize radio communications between two or more stations on-board a single aircraft supporting the safe operation of the aircraft and its systems.

Studies were conducted analyzing potential compatibility between proposed WAIC systems and incumbent services in the frequency bands 2 700-2 900 MHz, 4 200-4 400 MHz,

5 350-5 460 MHz, 22.5-22.55 GHz, and 23.55-23.6 GHz. Of the frequency bands studied below 15.7 GHz, only the frequency band 4 200-4 400 MHz was indicated to be feasible for sharing.

At the WP 5B meeting in October 2014, sharing between FS and WAIC in 22/23 GHz was discussed and the Working Document toward Preliminary Draft New Report M.[WAIC_Sharing 22/23 GHz] was elevated as PDNR.

2Preliminary Views

Japan is of the view that in order to implement the WAIC system, studies to prevent harmful interference to existing services are important. With respect to this agenda item, Japan supports the current ITU-R studies to support the WAIC system. Regarding the allocation of 22.5-22.55GHz and 23.5-23.6GHz to WAIC system proposed by US, sufficient studies should be conducted not to cause harmful interference to existing services.

Agenda item 1.18

to consider a primary allocation to the radiolocation service for automotive applications in the 77.5-78.0 GHz frequency band in accordance with Resolution 654 (WRC-12);

1Background

In accordance with Resolution 654 (WRC-12), a primary allocation to the radiolocation service for automotive applications in the 77.5-78.0 GHz frequency band will be considered under WRC-15 Agenda item 1.18. In this regard, ITU-R SG5 WP5A and WP5B conduct technical, operational and regulatory studies as responsible groups for WRC-15 Agenda item 1.18 with the help of other concerned groups.

CPM15-1 decided that WP5B is responsible for invitations i) & ii) and WP5A is responsible for invitations iii) in the Resolution 654 (WRC-12).

RESOLUTION 654 (WRC-12)

Allocation of the band 77.5-78 GHz to the radiolocation service to support automotive short-range high-resolution radar operations

The World Radiocommunication Conference (Geneva 2012),

...

invites ITU-R

to conduct, as a matter of urgency, and in time for consideration by WRC-15, the appropriate technical, operational and regulatory studies, including:

1. i.sharing studies and regulatory solutions to consider a primary allocation to the radiolocation service in the band 77.5-78 GHz, taking into account incumbent services and existing uses of the band;
2. ii.compatibility studies in the band 77.5-78 GHz with services operating in the adjacent bands 76-77.5 GHz and 78-81 GHz;
3. iii.spectrum requirements, operational characteristics and evaluation of ITS safety-related applications that would benefit from global or regional harmonization,

Regarding the study on operational characteristics, WP5A has developed a new Recommendation ITU-R M. 2057 - Systems characteristics of automotive radars operating in the frequency band 76-81 GHz for intelligent transport systems applications. Regarding the sharing and compatibility studies, WP5B has been developing a working document towards a preliminary draft new Report ITU-R M.[AUTOMOTIVE RADARS] - Systems characteristics and compatibility of automotive radars operating in the frequency band 77.5-78 GHz for sharing studies and a working document towards draft CPM text - Chapter 3 - Aeronautical, maritime and radiolocation issues (Agenda items 1.18).

2Preliminary Views

By realising automotive radar in the 76.0-81.0 GHz band through a primary allocation to the radiolocation service in the 77.5-78.0 GHz frequency band, it is possible to reduce traffic fatalities and injuries. Japan supports a primary allocation to the radiolocation service in the 77.5-78.0 GHz frequency band considering compatibility studies with existing services conducted by ITU-R.

Agenda item 2

to examine the revised ITU-R Recommendations incorporated by reference in the Radio Regulations communicated by the Radiocommunication Assembly, in accordance with Resolution 28 (Rev.WRC-03), and to decide whether or not to update the corresponding references in the Radio Regulations, in accordance with the principles contained in Annex 1 to Resolution 27 (Rev.WRC-12);

1Background

In response to Resolutions 28 (Rev.WRC-03) and 27 (Rev.WRC-12), the Director of the Radiocommunication Bureau is preparing a Report to the second session of CPM-15.

2Preliminary Views

Japan supports review of the reference to the ITU-R Recommendations in the RR on the basis of Resolution 27 (Rev.WRC-12) and Resolution 28 (Rev.WRC-03).

Agenda item 4

in accordance with Resolution 95 (Rev.WRC-07), to review the resolutions and recommendations of previous conferences with a view to their possible revision, replacement or abrogation;

1Background

In response to Resolution 95 (Rev.WRC-07), the Director of the Radiocommunication Bureau is preparing a Report to the second session of CPM-15.

2Preliminary Views

Japan supports review of recommendations and resolutions of the WRC considered in this agenda item on the basis of Resolution 95 (Rev.WRC-07).

Agenda item 7

to consider possible changes, and other options, in response to Resolution 86 (Rev.Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit;

1Background

Resolution 86 (Rev. WRC-07) resolves that WRC should consider any proposals which deal with deficiencies and improvements in the advance publication, coordination, notification and recording procedures of the Radio Regulations for frequency assignments pertaining to space services which have either been identified by the Board and included in the Rules of Procedure or which have been identified by Administrations or by the Radiocommunication Bureau, as appropriate. The resolution also resolves to invite WRC to ensure that these procedures and the related appendices of the Radio Regulations reflect the latest technologies, as far as possible. The Working Party 4A (WP 4A) is the responsible group for technical aspects, and Special Committee (SC) is the responsible group for regulatory and procedural aspects, of this agenda.

The Working Party of the SC (SC-WP) meeting held in December 2013 identified seven issues, and prepared materials for the draft CPM text on this issue for consideration at the SC meeting to be held in December 2014. The last WP 4A meeting held in July 2014 developed the CPM text on issues under this agenda item mainly on technical aspects. SC meeting held in December 2014 reviewed the outcomes of SC-WP and WP 4A and has developed its report to CPM 15-2 meeting which includes proposed changes to draft CPM report on some issues.

Some of these issues were also considered at the APG15-2 (June 2013, Bangkok, Thailand) and APG15-3 (June 2014, Brisbane, Australia).

2Preliminary View

Japan supports to review advance publication, coordination, notification and recording procedures for satellite networks subject to this agenda item in accordance with Resolution 86 (Rev. Marrakech, 2002). Japan is of the view that the principle that satellite networks should be brought into use after conducting necessary frequency coordination should be maintained, and that the procedures and associated regulations need to be reviewed, not in a comprehensive way which may cause an adverse impact on existing and future satellite networks, but through careful consideration of each issue under this agenda item, respectively taking into account rational and efficient uses of orbit/spectrum resources.

With respect to coordination and notice procedures, Japan supports the introduction of modern electronic means of communications in ITU-R because it can contribute to increased effectiveness in those procedures.

Japan does not support provisions for frequency assignments to be considered as having been brought into use in the event of a satellite failure during the ninety-day bringing into use period because such provisions may lead to abuse.

Agenda item 8

to consider and take appropriate action on requests from administrations to delete their country footnotes or to have their country name deleted from footnotes, if no longer required, taking into account Resolution 26 (Rev.WRC-07);

1Background

Resolution 26(Rev.WRC-07) urges administrations to review footnotes periodically and to propose the deletion of their country footnotes or of their country names from footnotes, as appropriate.

2Preliminary Views

Japan supports the deletion of country footnotes or country names in footnotes in the Table of Frequency Allocations in RR in accordance with Resolution 26(Rev.WRC-07), since it believes that the deletion of country footnote or country names in footnotes in the Table Frequency Allocations in RR does not influence any existing systems or existing services in Japan.

Agenda item 9

to consider and approve the Report of the Director of the Radiocommunication Bureau, in accordance with Article 7 of the Convention;

Agenda item 9.1

on the activities of the Radiocommunication Sector since WRC 12;

Issue 9.1.1

Protection of the systems operating in the mobile-satellite service in the band 406-406.1 MHz;

1Background

Resolution 205 (Rev. WRC-12) resolves to invite ITU-R to conduct operational studies with a view to ensuring the adequate protection of mobile-satellite service (MSS) systems in the frequency band 406-406.1 MHz from any emissions that could cause harmful interference (see No 5.267 of the radio regulations (RR)), taking into account the current and future deployment of services in adjacent bands, and also to invite ITU-R to consider whether there is a need for regulatory action, based on the studies carried out to facilitate the protection of the MSS systems in the frequency band 406-406.1 MHz, or whether it is sufficient to include the results of the above studies in appropriate ITU-R Recommendations and/or Reports.

ITU-R Working Party 4C (WP 4C) is the responsible group for this issue.

The 406-406.1 MHz frequency band is exclusively allocated to MSS, which is currently used by the Cospas-Sarsat system for search and rescue space segment instruments. Since the introduction of the first elements of the Cospas-Sarsat system in 1982 (the LEO and GEO components), more than 35 000 persons (end of 2012 data) have been rescued worldwide with the assistance of the information provided by the Cospas-Sarsat system. The information provided by the Cospas-Sarsat system has also significantly reduced the time needed for numerous rescue operations therefore reducing the cost and risks associated with such operations.

The protection criteria for this band are currently recognized through Recommendation

ITU-R M.1478, which provides allowable power flux-density requirements against wide-band out-of-band and narrow-band spurious emissions. However, this recommendation does not address aggregate emissions from transmitters operating in adjacent bands. Revision of the Recommendation ITU-R M.1478-2 is now being considered by WP 4C. The draft revised recommendation was approved by Study Group 4(SG 4) in July 2014.

At its meeting of February 2014, the WP 4C considered mitigation techniques to protect the MSS system in the 406-406.1 MHz. One of the techniques is to introduce improved filters for LEOSAR, GEOSAR and MEOSAR systems space receivers, which are planned for future generations of satellites. Another technique is a reduction in e.i.r.p. levels radiated by terrestrial systems towards space which may be another measure to protect the MSS systems in the 406-406.1 MHz. However, taking into account that there are already thousands of terrestrial systems in use throughout CEPT countries, it was recognized that it was not realistic to expect that the operators/users of these systems would/could modify their existing networks. As a result, this mitigation measure is concluded not to be feasible due to the high number of existing systems operating in the 406.1-410 MHz, but might be considered for existing systems operating over geographical areas with limited deployment of terrestrial systems and a very limited portion of that band such as 406.1-406.2 MHz.

At its meeting of July 2014, the WP 4C completed the development of a draft CPM text which includes modification of Resolutions 205(Rev. WRC-12) and new foot note 5.A911 to ensure the protection of MSS systems operating in the 406-406.1MHz.

2Preliminary Views

The Cospas-Sarsat system in the 406-406.1 MHz frequency band is essential for the protection of human life. On the other hand, there are already a huge number of existing services in the adjacent band.

In this light, Japan is of the view that adequate protection of the MSS systems in the 406-406.1 MHz frequency band is necessary while undue constraints are not imposed on the operation of existing services in the adjacent band.

Issue 9.1.2

Studies on possible reduction of the coordination arc and technical criteria used in application of No. 9.41 in respect of coordination under No. 9.7;

1Background

The WRC-12 adopted Resolution 756 (WRC-12) for ITU-R to study the appropriateness of the current criterion for No. 9.41 using ΔT/T, and of reduction of the coordination arc in some frequency bands, and to report it to the WRC-15. At the CPM15-1 meeting, Working Party 4A (WP 4A) was designated as the responsible group for technical aspects, and Special Committee (SC) was the responsible group for regulatory and procedural aspects of this issue. WP 4A developed the CPM text for this issue at its July 2014 meeting. The SC meeting held in December 2014 reviewed the CPM text developed by WP 4A and adopted not to develop its report to CPM 15-2 on this issue.

WP 4A and SG 4 are continuing to develop the new Report ITU-R S.[RES756] "studies on possible reduction of the coordination arc and technical criteria used in applicable or RR No. 9.41 in respect of coordination under RR No. 9.7".

This issue was also considered at the APG15-2 (June 2013, Bangkok, Thailand) and APG15-3 (June 2014, Brisbane, Australia).

2Preliminary Views

Japan cannot support any narrowing of the coordination arc and/or relaxing of the coordination threshold because these modifications may decrease the likelihood of identifying satellite networks having the potential to cause harmful interference. Japan believes that the foreseen consequences of such modifications should be carefully taken into consideration.

Issue 9.1.3

Use of satellite orbital positions and associated frequency spectrum to deliver international public telecommunication services in developing countries;

1Background

The WRC-12 adopted Resolution 11 (WRC-12) for ITU-R to examine the necessity of additional regulatory measures for satellite telecommunications in order to enhance the delivery of international public telecommunications services in developing countries and to report it to the WRC-15. Working Party 4A (WP 4A) was designated as the responsible group for this issue at the CPM15-1 meeting and the previous WP 4A meetings developed the CPM text on this issue at its July 2014 meeting. This issue was also considered at the APG15-2 (June 2013, Bangkok, Thailand) and APG15-3 (June 2014, Brisbane, Australia).

2Preliminary Views

Japan supports further study regarding this issue, as long as satellite network filings are treated on an equal basis among all members within the current regulatory framework of the Radio Regulations.

Issue 9.1.4

Updating and rearrangement of the Radio Regulations;

1Background

In accordance with Resolution 67 (WRC-12), ITU-R carried out studies during this study period and considered the issue of possible updating, review and potential revision of outdated information, and rearrangement of certain parts of the Radio Regulations (RR), except for Articles 1, 4, 5, 6, 7, 8, 9, 11, 13, 14, 15, 16, 17, 18, 21, 22, 23 and 59 and those parts which are revised on a regular basis.

On the basis of input contributions and documents for the meetings of the ITU-R responsible group, the following issues have been developed:

• – Issue A: 
  Modification to RR Article 2, and
• – Issue B: 
  Modification to the titles of some RR Articles for the purpose of better reflecting in the title the scope of these articles.

For Issue A, two options are proposed: Option A1 to keep unchanged RR Article 2 and Option A2 to modify RR No. 2.1 in order to delete the unused abbreviations provided in this provision.

For Issue B, two options are proposed: Option B1 to keep unchanged the RR and Option B2 to modify the title of RR Articles 37, 39, 40, 42, 43, 44, 47, 49, 50, 52 and 53.

2Preliminary Views

Japan supports the ITU-R studies.

Issue 9.1.5

Consideration of technical and regulatory actions in order to support existing and future operation of fixed-satellite service earth stations within the band 3 400-4 200 MHz, as an aid to the safe operation of aircraft and reliable distribution of meteorological information in some countries in Region 1;

1Background

Resolution 154 (WRC-12) invites the ITU-R to study possible technical and regulatory measures in some countries in Region 1 to support the existing and future fixed-satellite service (FSS) earth stations in the 3 400-4 200 MHz band used for satellite communications related to safe operations of aircraft and reliable distribution of meteorological information, considering that where an adequate terrestrial communication infrastructure is not available, FSS earth stations are the only viable option to augment the communication infrastructure in order to satisfy the overall communications infrastructure requirement of the International Civil Aviation Organization (ICAO) and to ensure distribution of meteorological information under the auspices of the World Meteorological Organization (WMO).

2Preliminary Views

When considering technical and regulatory actions in order to support existing and future operation of fixed-satellite service for civil aviation, it is necessary to take into account not only its protection but also frequency sharing with the other FSS applications and the other existing services. From such a view, as ITU-R studies are appropriate, Japan supports the results of the study.

Issue 9.1.6

Studies towards review of the definitions of fixed service, fixed station and mobile station;

1Background

Resolution 957(WRC-12) was adopted as WRC-15 Agenda item 9.1, Issue 9.1.6 at WRC-12.

Resolution 957(WRC-12) resolves to review the definitions of fixed service, fixed station and mobile station contained in Article 1 of RR for possible modification.

Resolution 957(WRC-12) also resolves to study the potential impact on regulatory procedures in the RR (coordination, notification and recording) and the impact on current frequency assignments and other services resulting from possible changes to the definitions of fixed service, fixed station and mobile station.

Agenda item 9.1, Issue 9.1.6 has been discussed at the WP1B meetings.

At the latest WP1B meeting, the following three conclusions were reached.

• - 
  It was concluded that there was no need to develop a new Report of the working document towards a preliminary draft new Report ITU-R SM.[RES.957] - Studies towards review of the definitions of fixed service, fixed station and mobile station.
• - 
  It was concluded that there was no need to change the definitions of fixed service, fixed station and mobile station.
• - 
  It was concluded there would be no change to the radio regulations apart from the suppression of Resolution 957(WRC-12).

These results of these studies have been described in the draft CPM text on Agenda Item 9.1 Issue 9.1.6.

The APT Preliminary views at APG15-3 showed that APT Members support the conclusion reached by ITUR-WP1B under this item i.e. no change to the Radio Regulations and suppression of Resolution 957(WRC-12).

2Preliminary Views

Japan supports the view that the current definitions of fixed service, fixed station and mobile station of the RR should remain.

This is because any revision of the definitions of fixed service, fixed station and mobile station should not have any influence on existing systems and existing services.

Issue 9.1.7

Spectrum management guidelines for emergency and disaster relief radiocommunication;

1Background

Resolution 647(Rev.WRC-12) was adopted as WRC-15 Agenda item 9.1, Issue 9.1.7 at CPM15-1.

Resolution 647(Rev.WRC-12) invites ITU-R to conduct studies as necessary, and as a matter of urgency, in support of the establishment of appropriate spectrum management guidelines applicable in emergency and disaster relief operations. Resolution 647(Rev.WRC-12) resolves to encourage administrations to communicate to BR, as soon as possible, the frequencies available for use in emergency and disaster relief.

Resolution 647(Rev.WRC-12) also resolves to reiterate to administrations the importance of having frequencies available for the use in the early stages of humanitarian assistance intervention for disaster relief.

This Agenda item has been discussed in WP1B as the responsible group. According to the contributions from administrations and organizations as well as the liaison statements from other Working Parties, WP1B developed three options of regulatory and procedural considerations to satisfy this issue.

Three options are as follows;

• - Option A 
  : modification to Resolution 647(Rev.WRC-12) and consequential suppression of Resolution 644(Rev.WRC-12);
• - Option B 
  : modification of Resolution 647 (Rev.WRC-12) only;
• - Option C 
  : suppression of Resolution 647(Rev.WR-12) and the consequential modification of Resolution 644(Rev .WRC-12);

2Preliminary Views

The ITU-R studies regarding spectrum management guidelines for emergency and disaster relief radiocommunication should be carefully observed.

Issue 9.1.8

Regulatory aspects for nano- and picosatellites;

1Background

The WRC-12 adopted Resolution 757 (WRC-12) which resolves to invite ITU-R to examine the procedures for notifying space networks and consider possible modifications to enable the deployment and operation of nanosatellites and picosatellites, taking into account their short development time, short mission time and unique orbital characteristics, and to instruct the Director of the Radiocommunication Bureau to report the results of these studies. The WRC-12 also adopted Resolution 808 (WRC-12) which addresses consideration of appropriate regulatory procedures needed for the nanosatellites and picosatellites as one of the preliminary agenda items for the WRC-18.

As for ITU-R, Working Party 7B (WP 7B) is the responsible group for this agenda item. WP 7B has developed the CPM text for this issue at its May 2014 meeting. WP 7B and SG7 have also developed at its October 2014 meeting the new Report ITU-R SA.2312-0 which describes technical characteristics and definitions of nanosatellites and picosatellites. Another new Report SA. [NANO/PICOSAT CURRENT PRACTICE], which gives an overview of the current practice for filing, notifying and deploying space networks, applicable to all satellites and on how they impact the nanosatellites and the picosatellites, is also under consideration by WP 7B.

Moreover, modification of Question ITU-R 254/7, which was proposed at WP 7B meeting held in October 2014 in order to take into consideration new issues related to the future growth of nanosatellites and picosatellites, and how to accommodate this growth, is to be considered in the future meeting.

This issue was also considered at the APG 15-2 (June 2013, Bangkok, Thailand) and APG 15-3 (June 2014, Brisbane, Australia).

2Preliminary Views

Japan is of the view that sufficient consideration is necessary in considering the regulations applicable to nanosatellites and picosatellites, so that any unacceptable impact on existing services and radio stations in operation or of planned operation in conformity with the Radio Regulations is avoided.

Agenda item 10

to recommend to the Council items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, in accordance with Article 7 of the Convention;

Preliminary Views

Japan proposes the following new Draft Agenda Items for WRC-19, and the details are described in Annexes 1 - 3, respectively.

• - 
  To consider identification of IMT in the frequency band(s) above 6GHz for the future development of IMT for 2020 and beyond
• - 
  To consider new regulatory provisions in Article 5, Chapter II of the Radio Regulations to introduce land mobile and fixed services operating in the bands above 275 GHz.
• - 
  To consider global harmonization of frequency bands for Intelligent Transport Systems (ITS) applications

New Agenda item Global Flight Tracking

consideration of global flight tracking, including, if appropriate, and consistent with ITU practices, various aspects of the matter, taking into account ITU-R studies;

1Background

The loss of Flight MH370 spurred worldwide discussions on global flight tracking. Determination of the position of an aircraft and reporting this information to air traffic control centres represents an important element of aviation safety and security. Flight tracking for civil aviation is currently available across the globe, apart from some parts of the polar regions.

Resolution COM5/1 was approved in ITU Plenipotentiary Conference in October 2014(PP-14) which is to add global flight tracking to the new agenda of WRC-15.

2Preliminary Views

Japan is of the view that it is necessary to study global flight tracking, taking into account appropriate protection of existing services.
