PRELIMINARY VIEWS ON WRC-15 AGENDA ITEM1.1, 1.2 AND1.4

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);

Resolution 233 (WRC-12)–Studies on frequency-related matters on International Mobile telecommunications and other terrestrial mobile broadband applications

1. Background

WRC-15 AI 1.1 was adopted 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(WRC12). At the first 2015 World Radiocommunication Conference Preparatory Meeting (CPM15-1), Joint Task Group 4-5-6-7was established as a responsible group to study forthis agenda item taking into account spectrum requirements from WP5D and WP5A.

JTG 4-5-6-7 has been conducting the sharing and compatibility studies on the suitable frequency ranges for mobile service provided by WG 5D and WP 5A and has updated working document towards preliminary draft CPM text for WRC-15 agenda item 1.1. The frequency ranges currently subject to studies within JTG 4-5-6-7 are as follows: 470-694/698 MHz; 1 300-1 527 MHz; 1 695-1 710 MHz; 2 025-2110 and 2200-2 290 MHz; 2 700-2 900 MHz; 2 900-3 100 MHz; 3 300-3 400 MHz; 3 400-4200MHz; 4400-4 900 MHz; 4 800-5 000 MHz; 5 925-6 425 MHz for IMT and 5350-5470 MHz, 5725-5850 MHz for RLAN.

Discussion on candidiate bands

JTG 4-5-6-7has received input contributions to express their views on the appropriateness or inappropriateness of the use of some frequency bands/ranges by terrestrial mobile broadband applications including IMT and aspects of these submissions are summarized in a table in the Annex 9 to Document JTG 4-5-6-7/584. Column 6 of the table includes the nature of proposal (quoted from the input contribution) and associated comments and explanations as provided by the entity submitting the contribution.Provided a variety of comment on candidate bands in the table, the draft CPM text included potential candidate bands under sharing and compatibility studiesbased on administrations’ proposals and analysis of results of studies.

At the APG15-2 meeting in July 2013, APT developed preliminary views on this agenda item based on input contributions from APT Members. Many administrations also expressed the views on candidate bands,whether supported or not, howeveran agreement was not reached and the list of candidate bands were embedded in the document APG15-2/OUT-19 (Rev.1) for further consideration. APT Members were also invited to contribute on this issue at APG15-3 meeting.

It is expected that a lot of contribution would be submitted to APG15-3 and needs to start the discussion of the APT preliminary view on candidate bands. All proposed candidatebands should be considered without excluding any band and commentson the appropriateness or inappropriateness of the band should be collected in a separate documentfollowing the working method as utilized within JTG 4-5-6-7.

RLAN in 5 GHz band

The ITU-R has indicated that the 5350-5470 MHz and 5725-5850 MHz frequency ranges would provide contiguous spectrum with the existing spectrum allocations for RLANs taking into RLAN devices utilizing in frequency bands 5150-5250MHz, 52505350MHz, 5470-5725MHz and 5725-5850MHz (in some countries).The band 5725-5850 MHz is already allocated to the mobile service in some countries including fifteen in Region in accordance with RR No.5.453 and it is noted that the band 5 725-5 875 MHz is designated to ISM application (see RR No.5.150).

2.Proposals

The Republic of Korea is of the view that APG15-3 should developthe APT preliminary view on candidate bands and the separate document to collect commentson the appropriateness or inappropriateness of the band based on input contribution from APT Members.

With that the Republic of Korea supports the bands 1452-1492 MHz, 3600-4200 MHz, and 4800-4900 MHz as candidate bands under AI 1.1 and IMT identification in the bands above 6 GHz is proposed under WRC-15 AI 10 as acompanion contribution (APG15-3/INP-XX).

The Republic of Korea also supports that the mobile allocation in the band 5 725-5 850 MHz be inserted in the Table of Allocation taking into account RR No.5.453.

The Republic of Korea would like propose to update the APT Preliminary views developed at the APG15-2 meeting as follows:

APT Members, in principle,support potential additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for International Mobile Telecommunications (IMT) in accordance with Resolution 233 (WRC-12).

While considering potential candidate bandsfor additionalidentification for IMT, APT Members support studies, currently being carried out by ITU-R.

APT Members are of the view that the ITU-R studies should also take into account;

-efficient use of spectrum[1] and resolves of Resolution 233 (WRC-12);

-the need for harmonization of spectrum bands to facilitate global roaming and to achieveeconomies of scale for IMT equipment development;

-spectrum requirements to address evolving needs, evolving technologies and user demand for IMT and other terrestrial mobile broadband applications as well as other services;

-sharing and compatibility issues with other services alreadyhaving allocations in the potential candidate bands and in adjacent bands considering the current and planned use of these bands by the existing services, as well as the applicable studies already performed in ITURfor the purpose of identification of the spectrum for IMT with respect to corresponding frequency bands being proposed for study.

The following bands are supported:

-1452 - 1492 MHz

-3600 - 4200 MHz

-4800 - 4900 MHz

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;

Resolution 232 (WRC-12)–Use of frequency band 694-790 MHz by the mobile, except aeronautical mobile, service in Region 1 and related studies

1. Background

WRC-12 adopted WRC-15 AI 1.2 to examine 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 take the appropriate measuresin accordance with Resolution 232 (WRC-12):

“resolves

1to allocate the frequency band 694-790MHz in Region1 to the mobile, except aeronautical mobile, service on a co-primary basis with other services to which this band is allocated on a primary basis and to identify it for IMT;

2that the allocation in resolves 1 is effective immediately after WRC15;

3that use of the allocation in resolves 1issubject to agreement obtained under No.9.21 with respect to the aeronautical radionavigation service in countries listed in No.5.312;

4that the lower edge of the allocation is subject to refinement at WRC15, taking into account the ITU-R studies referred to in invites ITU-R below and the needs of countries in Region1, in particular developing countries;

5that WRC15 will specify the technical and regulatory conditions applicable to the mobile service allocation referred to in resolves1, taking into account the ITU-R studies referred to in invites ITU-R below,”

There is a demand by many developing countries in Region 1 to use IMT systems in the 700 MHz frequency band in order to meet their needs, and in order to assist them to “bridge the gap” between their communication capabilities and those of developed countries.

The 700 MHz frequency band allows cost effective implementation of IMT for countries, in particular those with large areas and with low population density. From a spectrum usage perspective, and in order to deploy the national coverage with low cost, the 700MHz band is the most important in which to secure global harmonization and wide available bandwidth below 1GHz.In this regard, APT developed the harmonized frequency arrangements in the band 698-806 MHzand this arrangementis included in Recommendation ITU-R M.1036 as the A5 frequency arrangement.

The terrestrial broadcasting service provides a cost-efficient solution for high-quality media delivery in particular to populations in rural areas.

The use of the 700 MHz band for broadcasting varies considerably between countries.

Compatibility between the mobile service and other primary services to which the band is allocated and primary services in adjacent bands (in particular the broadcasting service and the aeronautical navigation service) needs to be ensured. ITU-R has been invited through Resolution 232 to undertake the relevant sharing and compatibility studies.

ThereforeITU-R JTG 4-5-6-7 is conducting sharing and compatibility studies on spectrum requirements for the mobile and broadcasting services and on the frequency arrangements for the mobile service adapted to the 700 MHz frequency band including the refinement of the lower band edge in order to support a fast implementation.In relation to WRC-15 AI 1.2, ITU-R WP 5D is developingharmonized frequency arrangements for IMT in the band 694 - 790MHz for Region 1.

Resolution 232 (WRC-12) invites ITU-R to also study solutions for accommodating applications ancillary to broadcasting requirements.

2. Preliminary Views

The Republic of Korea would like to propose to update the APT preliminary views developed at the APG15-2 meeting as follows.

•any possible regulatory actions under WRC-15 Agenda Item 1.2 should be limited to Region 1

•APT members support the studies being conducted in ITU-R in accordance with Resolution 232 (WRC-12)

•In the decisions of WRC-15 on Agenda Item 1.2, the integrity of GE-06 Agreement (in relation to I.R Iran needs to be ensured.

•No undue constraint should be caused to services allocated on a primary basis to administrations in Region 3.

•Necessary action to should be taken with a view to Iinclude the allocation of 696694-790MHz referred to in A.I 1.2 in Article 5 of Radio Regulation, as appropriate, based on the result of compatibility and sharing studies together with appropriate regulatory procedures

•In so doing so, from a global harmonization point of view, the channeling frequency arrangement(s) for the mobile serviceIMT need to be explored and adopted in the band below 790MHz, to the extent feasible, taking into account , to the extent feasible,channeling frequency arrangements in the band 698-806 MHz as currently contained in Recommendation ITU-R M.1036.

•It is noted that some parts of “APT preliminary views”, above in relation to Region 1 are outside the responsibility of Region 3.

For GE06 country in Region 3

-In the decisions of WRC-15 on Agenda Item 1.2, the integrity of GE-06 Agreement in relation to I.R Iran needs to be ensured.

Agenda item 1.4: to consider possible new allocation to the amateur service on a secondary basis within the band 5250-5450kHz in accordance with Resolution 649 (WRC12)

Resolution 649 (WRC-12) – Possible allocation to the amateur service on a secondary basis at around 5300kHz

  1. Background

Recognizing Resolution649 (WRC-12), in the current allocations to the amateur service in the HF bands, there is a significant jump, which causes many problems in terms of communication when the maximum usable frequency (MUF) falls below 7 MHz and the lowest usable frequency (LUF) is above 4 MHz, with the result that amateur stations would need to be able to access spectrum at around 5 MHz in order to fulfill their communication functions, particularly when they are engaged in providing emergency communications in response to disaster situations.

WRC-12 adopted WRC-15 Agenda Item 1.4, to consider possible new allocation to amateur service on a secondary basis within the band 5250-5450 kHz in accordance with Resolution 649(WRC-12). The frequency range 5250-5450 kHz is allocated to fixed and mobile (except aeronautical mobile) services in all three Regions on a primary basis. And WRC-12 decided that radiolocation services are also allocated in the range 5250-5275 kHz as a secondary services in Region 1 and 3 and primary in Region 2 and limited applications of the radiolocation service to oceanographic radars operating in accordance with Resolution 612(Rev. WRC-12).

As the working document toward the draft CPM text on WRC-15 agenda item 1.4 was updated at the last ITU-R WP5A in November 2013, the analysis of the Master International Frequency Register(MIFR) shows that 13314 frequency assignments in the fixed service, 2104 frequency assignments to base stations in the land mobile service, 251 frequency assignments to transmitting coast stations in the maritime mobile stations and 14 frequency assignments to receiving stations in the maritime mobile stations are recorded therein. Because the band 5 250-5 275 kHz has been already allocated and actively used by the incumbent services in Korea, it should be protected by any potential interference.

The working document towards a preliminary draft new report ITU-R M.[5 MHz COMPAT] is being developed in ITU-R WP5A for compatibility analysis of possible amateur systems with fixed, land mobile, maritime mobile and radiolocation services in the frequency band 5 250-5 450 kHz and the aeronautical mobile service in an adjacent band.

  1. Preliminary Views

The Republic of Korea proposes to update the APT preliminary views developed at the 2nd APG-15 meeting as follows:

APT Members support relevant ITU-R studies on this issue.

APT Members are of the view that amateur service should not be allocated on a secondary basis within the band 5 250-5 450 kHz unless the protection of the services to which the band is currently allocated and their future development should be is ensured., through appropriate technical, operational and regulatory measures, where required. No constraints should also be imposed upon existing services and their future development in the frequency band 5 250-5 450 kHz.
