1. About the COSPAS-SARSATCOSPAS-SARSAT is the system mainly founded by USA, France, Russia and Canada,
which receives the warning of aircraft or marine accidents and distribute them to theworld using the satellites. Transformation of the systems to the middle-orbit-satellites
including global positioning satellites such as Galileo is underway, aiming to achieve
IOC (Initial Operational Capability) in October 2019.
2. Outline of the Meeting
Schedule

From 5 to 11 June 2018

Venue

GSA (Global Navigation Satellite Systems Agency) (Prague, Czech)

Participants

78 people from 16 countries including USA, France, Russia, Canada,
and 1 organization
4 people of Maritime Safety Agency or ARIB participated from Japan.

3. Main results
Purpose of this meeting was to develop documents on operation and settle remaining
technical issues regarding land systems.

・ Problem of possible error alerts
It has been reported that there has been alerts that was normal in format but received
only once. America reported that this alerts were reduced by 80% by deleting the alert
which needed error correction 3 times or more.
・ The issue of slowly moving beacon
Russia and France proposed method to tackle the issue of large degradation of
accuracy in identifying the position of moving beacon at low speed, and positioning
accuracy for every speed classification was provisionally defined as a result.
Definitive conclusion was not reached because of the intention of the satellite providing
country, the result of which will be reported to JC-32 (32nd Meeting of the Joint
Committee) in October.

The 30th WP5D Meeting
2. Main results(1) 3GPP and China gave updates of proposal for IMT-2020 radio interface, and IMT-2020
documents (IMT-2020/3, 4 and 5) describing the input history were revised reflecting
the updates. (No update from Korea) Since ETSI / DECT Forum and TSDSI (India)
also made inputs for the initial proposal, IMT-2020 documents (IMT-2020/6 and 7) werecreated in the same way. In addition, a liaison statement was created to inform the
proponents and the independent evaluation groups about the inputs at this meeting.
(2) As the chairperson of AH-WORKPLAN proposed to hold workshop on IMT-2020
Terrestrial Radio Interface evaluation during the 32nd WP 5D meeting in July 2019, it
was decided that workshop should be compiled at the 31st WP 5D meeting in October.
(3) With regard to the evaluation of the IMT-2020 radio interface, information was
updated for the simulator from TTA and for the channel model related informationfrom Beijing Post and Telecommunications University and others, and they agreed to
be shared on the website for IMT-2020 evaluation.
(4) The draft CPM text on the compatibility study of IMT L-band and BSS (WRC-19 AI 9.1,
Issue 9.1.2), summarizes regulatory actions to be discussed in WRC-19. France andJapan jointly proposed the configuration change of the assumed regulatory actions in
the CPM text, which was deliberated at the meeting. After that, compromise wasreached by adding the two actions suggested by China : ((1) action to set the PFD(Power Flux Density) limitation values both for satellite and IMT, (2) action to specify
threshold to adjust satellite and IMT), while keeping all the actions described in the
joint proposal unchanged. The draft CPM texts for which WP 5D was responsible were
finalized, and liaison statement was sent to WP 4A where the same agenda was being
deliberated from the viewpoint of BSS (sound) receiver protection.
(5) Regarding the study on co-existence and compatibility of terrestrial and satellite
component of IMT (WRC-19 AI9.1, Issue9.1.1), America and other sector members
disagreed in various points such as description about MTC (Machine Type
Communication), about interference mitigation factors, about conclusion related to24

regulatory matter. The draft CPM texts for which WP5D was responsible were
finalized with the opinions from both sides described in them, and by adding the text
requesting resolution at the CPM19-2 (The 2nd Conference Preparatory Meeting forWRC-19). Liaison statement was sent to WP4C.
(6) Regarding the commencement of drafting the recommendation / report on the technicaland operational guidance on using HAPS (High Altitude Platform Station) as IMT basestations proposed from Japan, America expressed concern that it should be discussed
in an appropriate meeting if it is proposed as a new WRC (World Radiocommunication
Conference) agenda item. America and Iran etc. also suggested beginning with revisionof the recommendation related to existing HAPS.
(7) Although it had been agreed on the point that MTC could be introduced flexibly within
the existing IMT identified frequency bands, UAE suggested specifying the frequency
bands (3MHz-width-band x2 around 700MHz), whereas India insisted not to specify
them. After the deliberation, compromise was reached by adding text referring to thereport M.[IMT.MTC] under development, the draft CPM text was finalized, and liaison
statement was sent to WP 1B and WP 5A.
(8) In response to the liaison statement from WP 7A inquiring about the influence of thechange of UTC (Coordinated Universal Time) on IMT system, a reply liaison statement
was created based on the contribution from experts from Japan and America, andissued to WP 7A.
3. Next meeting schedule
The next 31st meeting is scheduled to be held in Japan from 9 to 16 October 2018.

The 3rd Study Group Meeting on Terahertz wave
