Seminar and Exhibition on Digital Terrestrial TV in Bolivia
Since Bolivia decided to adopt ISDB-T in July 2010 as its national digital TV standard,
digital terrestrial TV service has already been put in service by Bolivia TV (BTV) in
several major cities, including La Paz. With the Supreme Decree No.3152 issued by the
Bolivian government as of 19 April 2017, it is expected that the implementation of digitalterrestrial TV service in Bolivia would be accelerated.
Under such situation, expecting that the Bolivian broadcasters would get better
acquainted with the latest progress of digital terrestrial TV technologies for theirimplementation, and also to introduce the technical and engineering capabilities of theJapanese companies on their transmission equipment and systems, there was a seminarand exhibition on digital terrestrial TV held on 30 January 2018 in La Paz, Bolivia,
organized by the Vice Ministry of Telecommunications of Bolivia, co-hosted by Ministry ofInternal Affairs and Communications of Japan (MIC).
At this opportunity of being requested by MIC to participate together, ARIB/DiBEG
decided to dispatch its representative for this seminar and technical demonstration.

5G Experience

2. Main results(1) Initial description templates related to the proposal of candidate IMT-2020 radio
interfaces were received from 3GPP Individual Member, Korea and China, and new
IMT-2020 documents (IMT-2020/3, 4 and 5) describing the input history were created.
The liaison statement notifying these inputs were issued to the proponents andindependent evaluation groups. In addition, an input history of evaluation reports
from independent evaluation groups was also decided to be created. Independent
evaluation groups other than ITU members can also view these history documents.
(2) With regard to the evaluation of the IMT - 2020 radio interface, the source code for thesimulation from TTA and the source code for IMT-2020 channel model simulation from
Beijing Post and Telecommunications University, were provided. These are to beshared on the website of “IMT-2020 submission and evaluation process in future.
(3) For 1427-1518MHz, frequency arrangements for FDD and TDD that did not use
1512-1518MHz were proposed by ESOA (EMEA Satellite Operator's Association) with
the intention of protecting MSS (mobile satellite service).
Japan, Brazil, Finland, etc. opposed this proposal because the large number ofarrangements had been already proposed, and also it lacked compatibility with the G2
6

arrangement for FDD proposed by Japan etc.
On the other hand, Russia and Egypt supported the addition of arrangements,
insisting that their proposal should be taken into consideration in a situation wheresharing studies with MSS had not been completed. As a result of that, the proposedarrangements were added to the working document as G6 and G7.
For notes on this frequency arrangement, there was confrontation between two
parties. Japan, Germany, Brazil, and Finland argued that description indicating
frequency usage restriction should be avoided, while Russia, Inmarsat, and ESOA
insisted protection of the existing services provided on the frequencies below
1427MHz and above 1518MHz. It was decided that argument on the notes would becontinued.
(4) With regard to compatibility study of IMT L-band and BSS (WRC-19 AI 9.1, Issue
9.1.2), France, Japan and Korea proposed that a PFD (Power Flux Density) limitation
should be set, whereas China suggested that the conventional adjustment procedure
should be maintained due to fears that derived PFD limitation interferes with BSS
operation. In addition, the United States asserted that this study should be limited to
Regions 1 and 3, and all these claims were reflected in the working document of thepreliminary draft new report on the compatibility study, and the working document of
the draft CPM text for WRC-19 issue 9.1.2.
(5) Regarding the preliminary draft new report on MTC (Machine Type Communication),a background section was made on the basis of the Japanese contribution, andforecast information on MTC connection number by 2020 was added. In addition, theinformation was added to the preliminary draft new report showing use cases,transmission speed, coverage area where the device is deployed, battery life, and eventhe relationship between narrowband and broadband MTC.
(6) Tours to experience 5G, "SK Telecom 5G Experience" and "LG U+5G & Home Media
Experience" were offered at lunchtime or on the weekend during the meeting period,and many participants joined the Tours.

2. Major results
At this meeting, the draft APT proposal documents which are the basis for continuing
the previous meeting has been updated, for formulating the APT joint proposal in each
Agenda Item (AI) of WRC-19. The results of discussion on the main agenda are shown
below.
(1) AI 1.11: To facilitate global or regional harmonized frequency bands to support
railway radiocommunication systems between train and trackside within existing
mobile service allocations
Currently, the study is underway at the ITU-R for harmonization of frequency
usage. At this meeting, the following were agreed.
13 Supporting the study at ITU-R would be continued.
 It would be a provisional view that frequency harmonization of RSTT would not
restrict other primary work, that the study of RSTT in ITU-R would not be not
restricted to a specific technology, and that the study of frequency harmonizationof RSTT would support railway operation at the border..
In addition, it was agreed on a correction proposal of the draft CPM text (adding an
option to clarify that the revision of ITU-R Recommendation M.[RSTT_FRQ] is
included in the new decision) to WP5A
(2) AI 1.12: To consider possible global or regional harmonized frequency bands, to the
maximum extent possible, for the implementation of evolving Intelligent Transport
Systems (ITS) under existing mobile-service allocations
Currently, the study is underway at the ITU-R for harmonization of frequency
usage. At this meeting, the following were agreed.
 Supporting the study at ITU-R would be continued.
 It would be a provisional view that the development of ITS is not limited or
excluded by specific technologies including LTE based V2X, that frequency
utilization by ITS does not further restrict the primary work already being used
elsewhere, and that appropriate consideration should be given to theinterference from other primary work including mobile satellite service earth
station uplink.
(3) AI 1.13: To consider identification of frequency bands for the future development ofInternational Mobile Telecommunications (IMT), including possible additional
allocations to the mobile service on a primary basis
This AI is about the study of IMT system allocation for eleven candidate bands from24.25GHz to 86GHz.
Currently, the study is underway at the ITU-R for harmonization of frequency
usage. At this meeting, the following were agreed.
 Supporting the study at ITU-R would be continued.
 It would be a provisional view that priority should be given to 24.25-27.5 GHz for
identifying IMT on premises that the frequency sharing is possible, and thatoverlapping of frequencies with other services should be discussed on the basis of
the proposal at WRC-19.
Also, as a key point for future discussion, the priorities for each frequency band to
be studied for sharing and candidate for IMT identification of each country weresummarized. (Shown below)
