General Assembly of ITSF
ITSF (The ITS Info-communications Forum) was established to promote evolution of theroadway, transportation and automotive fields using highly advanced intelligent transportsystems (ITS), with a special focus placed on research and development and standardizationof information - communications technologies. The Forum consists of nearly 100 members
from industrial and governmental sectors, and ARIB act as a secretariat for it.
General Assembly of ITSF was held on 29 June 2023 at Meiji Kinenkan hall in Tokyo, asaround 60 members participated. Business report and financial statements for FY 2022 aswell as business plan and budget for FY 2023 were approved. Board members andManagement Committee members for 2023 were selected as well.
In the business report for FY2022, it was reported that activities were conducted for thepractical application and promotion of ITS wireless systems that contribute to safety,security, and convenience, as well as for the study of wireless communication methods
required for automated driving. The details of the report include: creation of "future visionand action plan" for changes in mobility and social issues, study of communication protocols
for V2X systems and ARIB standardization proposals for ITS platform extensions, and theproposals for the report "ITU-R M.[CAV] - Connected Automated Vehicles" and AWG (APTWireless Group) "Millimeter Wave ITS Applications in APT Member Countries". As activities
for international cooperation and promotion, the exhibition and support for MIC (Ministry ofInternal Affairs and Communications) sessions at the ITS World Congress Los Angeles,
reports on international trends and discussions in the ITSF on ITS radio systems,
automated driving and safe driving support at the "VSC seminar" held every year, werereported. In addition, the ITS radiocommunication experts meeting inviting ITS experts
from the U.S. and Europe, were also reported.
Regarding a business plan for FY2023, activities such as technical studies andstandardization proposals in cooperation with related parties for cooperative automateddriving, promotion of international standards on automated driving and wireless systems for
ITS and fostering the collaboration with overseas ITS experts were presented. New activities
in accordance with Vision and Action Plan was also revealed.

1Mr. Keiji Yamamoto, Senior Fellow of Toyota Motor Corporation, has been appointed as thechairman of the forum from 2023, taking after Mr. Sasaki.

The Fiscal 2023 General Assembly of 5GMF
The fiscal 2023 General Assembly of the 5GMF (The Fifth Generation Mobile
Communications Promotion Forum) was held on 5 July at Meiji Kinenkan hall in Tokyo.
About 165 members from telecommunication operators, equipment vendors, research
institutions such as universities and MIC (Ministry of Internal Affairs and Communications)participated in the Assembly.
All the agenda: (1) The business report and financial statements for fiscal year 2022, (2) The
business plan and budget for fiscal 2023 and (3) The candidates for officers were approved asproposed.
5GMF had conducted activities for the realization, dissemination and deployment of 5G
since its establishment in September 2014, and it has generally achieved its desiredobjectives. Considering this achievement, decision was made to review its organization andintegration of 5G promotion activities with that for 6G in line with changes in theenvironment.
The study of new promotion scheme which is expected to start on 1 April 2024 will be begun
after the Assembly, and additional General Assembly is planned before the end of march tovote on the scheme.

2The 6th APG23 (APG23-6) meeting
APG23 (Asia-Pacific Telecommunity Conference Preparatory Group for WRC-23) is
responsible for developing APT Common Proposal for the World Radiocommunication
Conference 2023 (WRC-23).
The 6th meeting of APG23 (APG23-6) which was final one before the WRC-23 was held
chaired by Dr. Kyu-Jin Wee (South Korea).
1. Outline of the meeting•Date: 14-19 August 2023
•Location: Brisbane, Australia (Online participation available)•Participants:
921 participants from 33 countries and regions, 136 participants as the Japanesedelegation headed by MIC, including 4 participants from ARIB.
2. Main results
At the meeting, Preliminary APT Common Proposals (PACPs) and the documents
including APT Views for each agenda item of WRC-23 were created. The results ofdeliberations on the main agenda items related to IMT (AI 1.1, 1.2, 1.4, and 10) areshown below.
(1) AI 1.1: Protection in the frequency band 4800-4990 MHz of stations of theaeronautical and maritime mobile services and review of PFD (power-flux density)
criteria
This Agenda, pursuant to ARC-19 Resolution 223, is to consider measures to protect
aeronautical and maritime mobile service stations operating in international
airspace and waters near the territory of the country operating the IMT station in
the 4800-4990 MHz band, and to reconsider the PFD limits imposed on IMT stations
in Footnote 5.441B of the Radio Regulations.
Japan has input a view to review the current regulations to promote the introductionof IMT while protecting the aeronautical and maritime mobile service stations.
As a result of the conflict between the assertion that the PFD limits are necessary
and the argument that they are unnecessary for the protection of aeronautical andmaritime mobile service stations, the PACP was not drafted at the meeting, and it
will continue to be discussed at WRC-23.
(2) AI 1.2: Identification of the following frequency bands 3300-3400 MHz, 3600-3800
MHz, 6425-7025 MHz, 7025-7125 MHz, and 10.0-10.5 GHz for IMTThis agenda item is to study, pursuant to WRC-19 Resolution 245, the identificationof IMT in the 3300-3400 MHz (revision of Region I footnote and Region II),
3600-3800 MHz (Region II), 6425-7025 MHz (Region I), 7025-7125 MHz (all regions)and 10.0-10.5 GHz bands (Region II).
Japan submitted a contribution to support the global identification of the 7025- 7125
MHz frequency band as terrestrial IMT on the condition that the protection ofexisting primary services is ensured and no additional restrictions are imposed, on3

the premise that the sharing and compatibility of IMT and existing services can berealized, and to support the identification of 3600-3800 MHz and 6425-7025 MHz,
which are the targets for consideration in other regions.
As a result of the discussion, PACP was drafted to support the possibility of global
IMT identification for frequencies between 7025 and 7125 MHz, revising thesupplementary draft resolution that define method for protecting existing
Fixed-satellite service.
On the other hand, it was concluded that PACPs for 3600-3800 MHz and 6425-7025
MHz should not be prepared, mainly because they are on the agenda of other regions.
Instead, the APT View was agreed on which stated that IMT identification in otherregion should not interfere with existing 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 2.7 GHz already identified for IMTThis Agenda is to study the use of High Altitude Platform Stations (HAPS) as IMTbase stations in mobile operations in the frequency band below 2.7 GHz alreadyspecified in IMT globally or regionally in accordance with WRC-19 Resolution 247.
Japan submitted a joint contribution with Papua New Guinea, Samoa, Tonga andVanuatu supporting the identification of all IMT frequency bands underconsideration (694 to 960 MHz, 1.7 GHz band, 2 GHz band, and 2.5 GHz band) as
HIBS on the condition that the protection of existing primary services are ensured.
After discussion, it was agreed to identify all the frequency bands except for 694-960
MHz as HIBS, and a PACP was drafted. With regard to 694-960 MHz, a PACP was
not agreed upon because some countries raised concerns about interference toexisting broadcasting operations.
(4) AI 10 (related to the Agenda Items of WRC-27): Identification of additionalfrequency bands for IMTRegarding the identification of additional IMT frequencies, Japan proposed
12.75-12.95 GHz as a frequency to be studied. Various candidate frequencies such as4400-4800 MHz, 6425-7025 MHz (Region 3), 7.125-8.5 GHz, 14.5-15.35 GHz were
proposed by other countries. However, concerns were raised in most frequency bands,
and a PACP was not drafted. Instead, the APT View that supports study of theidentification of IMT for 4.4-15.35 GHz was agreed upon.
3. Future meeting schedule
The agreed PACP will continue to be voted on by the APT countries for approval andwill be submitted to WRC-23 (held from 20 November – 15 December 2023) as a formal
APT Common Proposal (ACP).
