5G International Symposium 2020 in TokyoJapan’s Ministry of Internal Affairs and Communications (MIC) hosted an international
symposium in February entitled “5G International Symposium 2020: Creating the Futurewith 5G”. This symposium, co-hosted by the Fifth Generation Mobile Communications
Promotion Forum (5GMF) and ARIB, and supported by the Telecommunication
Technology Committee (TTC), was held in order to present the results of the MIC
organized 5G Field Trials by participants from a diverse range of use fields as part of
MIC’s activities towards the realization of 5G in 2020.
Participants at the symposium were able to experience a future where 5G is realized
through exhibitions and demonstrations of the 5G Field Trials, which helped to facilitate
the dissemination of the results of this year’s trials both domestically and internationally.
Presentations and panel discussions with key stakeholders in the world of 5G were also
held, in which ideas were discussed and opinions were exchanged that will assist inaccelerating the realization of 5G.
Lively discussions were held over the two days of the symposium among the almost 1000
participants in attendance, including those from three countries and regions in Asia
(Turkey, Indonesia, and South Korea) and 5G stakeholders from both universities andprivate industries.
Measures were also put into place to counter the spread of the novel coronavirus. These
measures included emails sent to registered participations to bring attention to thesituation as well as precautionary measures participants could take, the placement of
alcohol based hand sanitizers at the venue along with posters explaining how to properly
use them, as well as a manual created and kept on hand to provide information andprotocols as to what should be done in case participants fell ill during the event.

2. Main results(1) General Aspects① On Research Subject Q262/5 (Usage of the terrestrial component of IMT systems for
specific applications), it was agreed that preparation of ITU-R report on the use of
C-V2X (Cellular V2X) be started and would be completed by June 2021.
(2) Spectrum Aspects & WRC-23 Preparation① It was decided to establish SWGs for each of the following WRC-23 agenda items forwhich WP5D will be responsible, and to promote future study of frequency sharing
and preparation of CPM texts.
 AI 1.1: to consider, based on the results of the ITU-R studies, possible measures
to address, in the frequency band 4800-4990MHz, protection of stations of theaeronautical and maritime mobile services located in international airspace andwaters from other stations located within national territories, and to review thePFD criteria in No. 5.441B in accordance with Resolution 223 (Rev.WRC-19)
 AI 1.2: to consider identification of the frequency bands 3 300-3 400 MHz, 3
600-3 800 MHz, 6 425-7 025 MHz, 7 025-7 125 MHz and 10.0-10.5 GHz forInternational Mobile Telecommunications (IMT), including possible additional
allocations to the mobile service on a primary basis, in accordance with
Resolution 245 (WRC-19)
 AI 1.4: to consider, in accordance with Resolution 247 (WRC-19), the use ofhigh-altitude platform stations as IMT base stations (HIBS) in the mobile
service in certain frequency bands below 2.7 GHz already identified for IMT, on a
global or regional level② Regarding the frequency assignments in the band identified for IMT in WRC-19(24.25-27.5 GHz, 37-43.5 GHz, 45.5-47 GHz, 47.2-48.2 GHz and 66-71 GHz),
existing recommendation on frequency assignment ITU-R M.1036-6 was agreed tobe revised by June 2020.
(3) Technology Aspects① A document (IMT-2020/38) summarizing the evaluation for the wireless interface
results proposed by an evaluation group outside ITU-R has been created.
② As a first step toward future wireless technology development, it was agreed that
ITU-R report on technology trends toward 2030 (Tentative title: IMT futuretechnology Trend) would be made and completed by June 2022.
