At this meeting, APT Preliminary Views were prepared as the basis for developing of
APT Common Proposals for each agenda item of WRC-23. The results of deliberations on
the main agenda items related to IMT (AI 1.1, 1.2, 1.4 and 10) are shown below.
(1) AI 1.1: Protection in the frequency band 4800-4990MHz of stations of theaeronautical and maritime mobile services and review of PFD (Power Flux Density)
criteria
It was agreed that the APT Preliminary View is to support the on-going ITU-R
studies relating Agenda Item 1.1, and this view was proposed by several APT
Members including Japan through input contributions. On the other hand, regarding
protection of stations of aeronautical and maritime mobile services located ininternational airspace and waters, APT members could not reach a consensus,
therefore, discussions were decided to be continued.
(2) AI 1.2: Identification of following frequency bands 3300-3400MHz, 3600-3800MHz,6425-7025MHz, 7025-7125MHz and 10.0-10.5GHz for IMTIt was agreed that the APT Preliminary View is to support potential IMT
identification in the frequency band 7025-7125 MHz, in line with Japan's proposal,
however, it was decided that the identification of the frequency bands
3600-3800MHz and 6425-7025MHz for IMT will be discussed further and any
possible IMT identification in the above-mentioned frequency bands in otherRegion shall protect existing primary services in Region 3.
(3) AI 1.4: Use of HIBS (HAPS as IMT Base Stations) in the mobile service in certain
frequency bands below 2.7GHz already identified for IMT
As a result of the discussion, considering the fact that the ITU-R studies related tothis agenda item is still going on, it was decided that APT Preliminary View is tosupport the ongoing ITU-R studies for establishing a new globally or regionallyharmonized regulatory framework for HIBS with a view to providing flexibility ofspectrum usage for HIBS in certain frequency bands below 2.7 GHz alreadyidentified for IMT, while ensuring the protection of the existing services.
Proposals of Japan to support stipulating a provision in the Radio Regulations (RR)
for HIBS operations at the altitude that could go down to 18 km, and to consider thatthe studies on HIBS UE should be treated as the outside the scope of this agenda
item, were not agreed and were brought to future discussion.
(4) AI 10 (related to the Agenda Items of WRC-27): Identification of additional frequency
bands for IMTConsideration of the identification of additional frequency bands for IMT wasproposed as the Agenda Item of WRC-27 by Vietnam (specifically the frequency
bands 7.125-24GHz and 92-300GHz) and Korea, which was supported by China.
However, countries which place importance on satellite communication expressed
skeptical opinions regarding use cases and demand, therefore, this AI will bediscussed at the next meeting.

SDOs in China, Korea and Japan.
1. Outline of the meeting•Schedule:

26 and 29 August 2022

•Venue/Method:

Online meeting•Participants:

CCSA: 49 people, TTA: 17 people, ARIB: 22 people

2. Main results(1) The results of the 4th Meeting of the APT Conference Preparatory Group forWRC-23 (APG23-4), ITU-R SG5 the 41st WP5D meeting and the recent 3GPP
meeting were shared, views were exchanged on the future issues to be studied.
(2) For the 42nd WP5D meeting scheduled to be held from 10 October, progress of thepreparation in each country was shared, joint contribution was discussed, and items
for further study and work contents were identified.
(3) Regarding the revision of ITU-R Recommendation on unwanted emission
characteristics for IMT-Advanced, opinions of each country were exchanged, and it
was decided that discussion including the possibility to develop joint contributions
would be continued by email.
(4) Status of studies and views of each country on the ITU-R Recommendation “IMTVision for 2030 and beyond” which has been developed for Beyond 5G
standardization was shared, and policies for scrutinizing the items that should beincluded in the recommendations and how to proceed with future studies werediscussed. In addition, it was agreed that exchange of opinions by e-mail aiming fora joint contribution regarding the timeline described in the Vision Recommendation.
(5) Opinions were exchanged on the identification of additional frequency bands for IMT
which is being considered as a new agenda item for WRC-27. Discussion was decided
to be continued for possibility of joint contribution describing the necessity of theidentification of additional frequency bands for IMT toward the next APG23-5
meeting.
