SaT5G Achievements vs. Target KPIs in Standardisation

The following table illustrates the SaT5G standardisation related achievement vs. target KPIs defined in the DoW. As can be easily deduced, the SaT5G project has achieved and even exceeded the standardisation related target KPIs set in the DoW.

Cooperation with external stakeholders, both from satellite and terrestrial cellular communications industry

- Cooperation with external stakeholders outside the SaT5G project has been regular in the context of 3GPP as part of the on-going Rel-16 study items. These external stakeholders include both satellite and terrestrial cellular communications industry.
  - At 3GPP SA, RAN Plenaries #80 (11-15 June 2018, La Jolla, CA, USA), >60 3GPP member organisations, from both SatCom and non-SatCom industries, supported the proposed study/work items initiated by TAS on the integration of SatCom into 5G during Release 16.
  - During the 3GPP Rel-16, the satellite/non-terrestrial networks topic was prioritized among the candidate study items (pre standardisation phase) to be executed. This was made possible thanks to the support of 55 organisations as reflected in RP-190710 “Study on solutions for NR to support non-terrestrial networks (NTN)”. Among the supporters, one can notice that EBU and BBC provided their support. This study has been completed on 28 November 2019.
  - As per 3GPP Rel-17, the satellite/non-terrestrial networks topics is being prioritized among candidate work items (normative phase) in both TSG SA & RAN as per preliminary decisions of RAN#85 and SA#85 as reflected in SP-190949 & SP-190951. This was made possible with strong involvement of >25 organisations (most from cellular industry) in the Rel-16 studies.
- In the context of ETSI, it shall be noted that the ETSI/SES/SCN (Work Item: DTR/SES-00405 – TR 103 611: “Satellite Earth Stations and Systems (SES); Seamless integration of satellite and/or HAPS (High Altitude Platform Station) systems into 5G system and related architecture options” has been reviewed by at least 10 organisations among which HNS, Inmarsat, ESA, CNES which are not part of the SaT5G project. In ETSI TC-SES, this is quite unusual to have this amount of organizations involved in drafting/review the same document.

Thanks to partial support of SaT5G project, the SaT5G project partners attended a considerable amount of SDO meetings where a significant amount of contributions were submitted and presented by SaT5G project partners:
