ITU-R WRC-23
World Radiocommunication Conferences (WRC) are held every three to four years by ITUR to review, and, if necessary, revise the Radio Regulations, the international treaty
governing the use of the radio-frequency spectrum and the geostationary-satellite and nongeostationary-satellite orbits. Recent WRC (WRC-23) was held from November toDecember 2023 in Dubai, UAE, where H.E. Eng. Mohammed Al Ramsi from UAE chaired.
1. Outline of the Meeting• Schedule: 20 November - 15 December 2023

• Venue: Dubai, United Arab Emirates• Participants : 3,985 participants (Administration, Telecommunication Operators,Vendors), 112 participants from Japan (3 participants from ARIB)
2. Main results associated with Land mobile service(1) Agenda Item 1.2 --- Identification of the frequency bands 3300-3400 MHz, 3600-3800
MHz, 6425-7025 MHz, 7025-7125 MHz and 10.0-10.5 GHz for International Mobile
Telecommunications (IMT), including possible additional allocations to the mobile:
The following frequency bands were agreed to be identified for IMT in each Region.
6425-7025 MHz in the Region1, Part of Region2, Part of Region37025-7125 MHz in the Region1, Part of Region2, Region3(2) Agenda Item 1.4 --- The use of high-altitude platform stations as IMT base stations(HIBS) in the mobile service in certain frequency bands below 2.7 GHz alreadyidentified for IMT, on a global or regional level:
The following frequency bands had been under discussion.
694-960 MHz, 1710-1885 MHz, 2500-2690 MHz (Newly added frequency bands)
1885-1980 MHz, 2010-2025 MHz, 2110-2170 MHz (Frequency bands for which
requirements were revised)1

694-960 MHz band has been identified for HIBS in Region1 and 2, and in 14 countries
stated in the footnote in Region 3. All the other frequency bands have been identified
for HIBS in all Regions.
(3) Agenda Item for WRC-27 --- Additional identification of frequency bands for IMT andUse of IMT identified bands for MSS (Mobile-Satellite Service):
The following frequency bands were agreed to be studied as candidate for IMT
identification.
4400-4800 MHz, 7125-8400 MHz, 14.8-15.35 GHz
It was decided that 694/698 MHz-2.7 GHz band which had been identified for IMT
would be studied to be used for MSS, which enable direct communication between
mobile terminals and satellites.
3. Future plan
Studies will be conducted through each SGs (Study Group) and WPs (Working Party)
which act under SG in ITU-R, and through Asia-Pacific Telecommunity.

The 69th IMT Working Group Meeting of CJKCJK IMT Working Group Meeting is aiming to exchange information and views about theactivities of international IMT standardizations in ITU-R, APT, 3GPP and so on, among
SDOs in China, Korea, and Japan, and also to work on joint contributions to the ITU-R
SG5 WP5D.

• Format: Online meeting• Participants : CCSA 52 participants, TTA 18 participants, ARIB 22 participants
2. Main results(1) The results of the RA-23, WRC-23, CPM27-1 and the recent 3GPP meeting wereshared, and the participant views were exchanged on the future issues to be studied.
(2) For the 45th WP5D meeting scheduled to be held from 31 January, the progress ofthe preparation in each country was shared, a joint contribution was discussed, anditems for further study and work contents were identified.
(3) Since the next 45th WP5D meeting would be the first time in the new study periodof 2024-2027 in ITU-R, it was decided to discuss the need to improve the structure ofWGs, etc. of WP5D and continue the exchange of opinions.

2(4) Regarding the report on the technical performance requirements for the IMT-2030
radio interface, which will be prepared as the next step after the IMT-2030
Framework Recommendation was approved at RA-23, information was shared on thestudy status and ideas of each country. The possibility of preparing a joint
contribution was also decided to continue to be discussed.
(5) Regarding the identification of frequency for IMT which had been set in WRC-27 AI
1.7, it was decided to continue discussing the parameters necessary for study offrequency sharing.
3. Next meeting schedule
The next CJK IMT Working Group Meeting will be held in Beijing in May 2024.

MSC (Mobility & Safety Communications) Seminar in TokyoITS Info-communications Forum (ITSF) for which ARIB acts as a secretariat held "Mobility & Safety Communications (MSC) Seminar" at Meiji Kinenkan hall in Tokyo on 22January 2024.

MSC Seminar

The 32nd Meeting of APT Wireless Group (AWG-32)
APT (Asia-Pacific Telecommunity) Wireless Group, AWG, studies the harmonization ofspectrum usage and standardization aiming at the enhancement and dissemination ofradiocommunication systems in the Asia-Pacific region. The meeting has been held usually
about twice a year, and the experts of the wireless technologies of each country in this region
join the meeting, where Mr. Le Van Tuan (Vietnam) acts as a chairperson.
1. Outline of the Meeting• Schedule:

4 - 8 March 2024

• Venue/Method: Pattaya, Thailand (Online participation available)• Participants:
333 participants from administrations, private organizations, and international

4organizations in the Asia-Pacific region, 90 participants as the Japanese delegation
headed by MIC including 4 participants from ARIB
2. Main results
AWG has four working groups: WG on Harmonization, WG on IMT, WG on Terrestrial,and WG on SAM (Space, Aeronautical, and Maritime), in each of which sub-working
groups or task groups have been established for the issues significant to APT Members.
The main results of the meeting related to IMT and ITS are described below.
(1) The report "APT Report on trends and spectrum developments for IMT usage in2025 – 2030 in Asia-Pacific region" has been completed. This report describes 5G
deployment, frequency allocation, future deployment plans, etc. in 12 countries.
(2) Questionnaire responses from six countries regarding the new draft report on IMT
spectrum valuation and pricing were incorporated into the working document. This
report had been scheduled to be completed at this meeting, but it was decided to be
postponed to the next meeting in order to enhance its content further.
(3) Regarding the new draft report on studying how to deploy 5G systems for various
use cases, case studies from three countries were submitted and incorporated into theworking document. Although further two suggestions for modifying the working
document were submitted, they will continue to be worked on to combine and will be
submitted at the next meeting because they had differences in the introduction andthe scope.
(4) Questionnaire responses were received from seven countries, regarding the newdraft report on the survey on voluntary terminal certification by mobile carriers, andthese were incorporated into the working document. This report is scheduled to becompleted at the next meeting.
(5) As discussion about IMT-2030 had been becoming more active in ITU-R WP5D and3GPP, two organizations proposed holding a 6G workshop, and plans for theworkshop have been drawn up. The first workshop at the next meeting, it will beheld on a small scale within APT, but in the future, inviting external organizations isconsidered.
(6) Based on the two contributions from Japan regarding milli-meter wave
radar/sensors for ITS: 1) a proposal to issue a questionnaire requesting each country
to provide relevant information, and 2) a proposal on the framework for the new draft
APT report reflecting the questionnaire responses, the questionnaire to be sent wasagreed on. Also, a working document for the new draft APT report was created.
(7) A working document of the new draft report was created based on the contribution
from Japan which introduce Vehicle – Infrastructure Cooperation System such as
Smart Pole and its use cases.

The next AWG meeting is scheduled to be held on 9 -13 September 2024, in Bangkok,Thailand.
