The 29th Meeting of APT Wireless Group (AWG-29)
The 29th Meeting of APT Wireless Group (AWG-29) was held online in March.
 About the APT Wireless Group (AWG)
APT (Asia-Pacific Telecommunity) Wireless Group, AWG, studies the harmonization andstandardization of the frequency and technical matters aiming at enhancement anddissemination of wireless communication systems in the Asia-Pacific region. The meetinghas been held usually twice a year, and the experts in the wireless technology of eachcountry in this region join the meeting.
Mr. Le Van Tuan (Vietnam) chaired the meeting.
 Outline of the Meeting•Schedule: 21 - 29 March 2022

•Meeting: Online•Participants: 491 people from administrations, private organizations and internationalorganizations in the Asia-Pacific region,77 people as the Japanesedelegation headed by MIC, including 5 from ARIB Main results
1. Formation for study
This time, formation for study was restructured into four WGs (Harmonization, IMT,Terrestrial and SAM (Space, Aeronautical and Maritime)) and AFIS (APT Frequency
Information System) Ad Hoc. Chairperson of each WG was elected.
2. IMT(1) WG Spectrum Aspects• A new ITU-R Report "RELEVANT INFORMATION FOR CONSIDERATIONS ON
THE POSSIBLE IMPLEMENTATION OF IMT IN THE FREQUENCY BAND 1427

1

- 1518 MHz" related to frequency arrangement has been completed.
• Drafting of a new ITU-R Report on the method of sharing 1980 - 2010 MHz and2170 - 2200 MHz band was finished. A final agreement was carried over to the next
meeting in order to take time to check the document.
(2) WG Technology Aspects• The draft new report on the introduction of 5G at frequency band above 24.25GHz
was revised.
• Regarding the draft new report on OTA (Over The Air) measurement, expansion ofthe scope of study to include technical information and progress in specification workin 3GPP was decided.
• It was newly proposed to prepare a report summarizing the issues and solutions
related to area development for various 5G use cases, and it was agreed to start thiswork.
3. ITS• Regarding the draft new report of Cellular V2X, the description of the appendix
detailing the related technology has been updated and will be completed at the nextmeeting.
• For the draft new report of the millimeter-wave application on ITS, the positioning
method that predicts the shielded area and its verification results were added. It wasdecided that completion of the draft would be postponed to the meeting to be held onFall 2023.
 Future meeting schedule
The next AWG-30 meeting will be held in Bangkok from 5 to 9 September 2022, incombination with a web conference.

CJK the 64th IMT Working Group MeetingCJK IMT Working Group Meeting is aiming to exchange information and views about theactivities of international IMT standardizations in ITU-R, APT, 3GPPs, and so on, among

 Main results(1) The results of AWG-29 (March 2022), ITU-R SG5 WP5D the 40th (February), theWP5D WG Spectrum Interim (April) and the recent 3GPP meetings were shared.
The issues to be studied were also agreed on.
(2) For the 41st WP5D meeting scheduled to be held from 13 June 2022, preparation
status of each country was reported, and discussions were held on joint contributions.
Items to be continuously examined and work items were identified there.
(3) Information on the status and ideas of each country's preparation for Future
Technology Trends report and Vision recommendation leading to Beyond 5G
standardization was exchanged. The contents to be included in each report /recommendation and how to proceed with future studies were discussed.
Furthermore, for the Future Technology Trends report, it was decided that exchangeof opinions by e-mail would be continued toward preparing a joint contribution
regarding the policy for organizing the document contents, aiming at the finalization
at the next meeting.
(4) As a result of discussions based on Korea's proposal at the previous meeting toactively deal with difficult issues in order to take advantage of the opportunities ofCJK IMT WG, it was agreed that the joint contribution on "IMT plan for 2030 andbeyond" would be prepared.
 Next meeting schedule
The next CJK IMT Working Group Meeting is scheduled to be held around September
2022.

Radio Day Memorial Lecture"Radio Day Memorial Lecture" was held on 3 June 2022, organized by ARIB, co-sponsoredby the Council for Info-Communications Promotion Month, and supported by the MIC.
This is the first time in three years to welcome the audience to the venue, IINO HALL inTokyo. The lecture was also streamed for audience across the nation.
"Radio Day" was established in 1951 memorizing the enforcement of the laws related toradio wave regulations on 1 June 1950 in Japan.
Main theme of the Lecture was "Current status and future prospects of radio wave usage".
