Symposium to Promote Safe and Secure Radio Usagein Medical Institutions
The Ministry of Internal Affairs and Communications (MIC) and the Electromagnetic
Compatibility Conference Japan (EMCC), for which ARIB works as secretariat, held a
Symposium to Promote Safe and Secure Radio Usage in Medical Institutions on 8 March
2021, and delivered it in an on-demand style.
In this symposium, MIC and EMCC introduced the possibility of using new radio wave
applications, such as 5G, in medical institutions and usage examples of radio wave andICT applications contributing to measures against novel coronavirus infections. At thesame time, MIC and EMCC held a panel discussion on management systems for the safe
and secure use of radio waves, including practical examples.
The symposium was participated by 1052 audiences, 54% of whom are engaged in medicalcare and 16% were involved in the manufacture of medical equipment.
The program of the Symposium was as follows.

The 27th Meeting of APT Wireless Group (AWG-27)
The 27th Meeting of APT Wireless Group (AWG-27) 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 telecommunication of wireless communication systems in the
Asia-Pacific region. The meeting has been held usually about twice a year, and theexperts of the wireless technology of each country in this region join the meeting.
Mr. Le Van Tuan (Vietnam) served as a chairperson.
 Outline of the Meeting•Schedule: 22 - 30 March 2021
•Meeting: Online•Participants: 520 people from administrations, private organizations andinternational organizations in the Asia-Pacific region,
67 people as the Japanese delegation headed by Mr. SATO Tsukasa(Deputy Director of International Frequency Policy Office, MIC)
including 5 from ARIB Main results
In AWG, three working groups (WG: Frequency, Technology and Service/Application)
were set, in each of which sub working groups or task groups have been established forthe issues.
The main results of the meeting from each WG were as follows.
(1) WG Spectrum Aspects• Drafting Groups were created for two of the study items : ① Study of frequency
sharing between IMT and MSS (Mobile-satellite service) in 1.5GHz and 2.1GHz
band, ② Study of measures enabling frequency sharing between 4G-LTE and5G-NR system in 3.3GHz and around 3.6GHz band, for which working documents
were revised.
(2) WG Technology Aspects• Test method under the OTA (Over the Air) condition was set as a new study item,and working plan was created.
• Work on the Report on Cellular V2X and Application of millimeter wave on ITS were
undergoing respectively, the former of which reflected ITS technologies in 5.9GHz
band and status in each member country, and the latter reflected the example of new
application of millimeter wave radar with communications.
(3) WG Service and Applications• The new report "Railway radio communication system for passenger access toinformation and internet services in some APT countries" was completed.

3 Future meeting schedule
It was announced from APT secretariat that the next AWG-28 meeting would be plannedin September and that probably be held online.

 Main results
At this meeting, APT Preliminary Views were drafted, as base of APT Common
Proposals for each Agenda Item (AI) in WRC-23. AIs under discussion were as follows.
(1) AI 1.1: Revision of PFD (Power Flux Density) applied to IMT station in 4800 4990MHz band(2) AI 1.2: Study on identification of following frequency bands to IMT service
3300 - 3400MHz, 3600-3800MHz, 6425-7025MHz, 7025-7125MHz and10.0-10.5GHz(3) AI 1.4: Use of HIBS (HAPS as IMT Base Stations) in IMT identified bands below
2.7GHz Future meeting schedule
Although details of the schedule have not be announced yet, next meeting is likely to set
within the year 2021 for 6 - 7 days. Further, two meetings are planned in 2020.

<Achievement>
The Task Force for Next-generation Digital Terrestrial Television has shared know-how
gained in relation to the next-generation digital terrestrial television broadcasting being
developed in Japan, with those countries that have adopted ISDB-T (Integrated ServicesDigital Broadcasting - Terrestrial, originally developed in Japan) system in order to assist
them in the study of their next-generation systems. The group has contributed tostrengthening technological collaboration between Japan and these countries as well as todevelopment in the area of broadcasting in these countries, and the group's continued
contributions are anticipated.

Radio Day Memorial Lecture"Radio Day Memorial Lecture" was held online on 4 June 2021, organized by ARIB,
