The ALIX project aims at supporting active participation in the 3GPP standardisation process to define the 5G satellite component and its interfaces with other networks as well as the creation of a critical mass to influence this standardisation process.
The proposed activity is to support standardisation actions, help develop contributions and advocate positions favourable to the SatCom sector within the 3GPP standardisation process such that they result in tangible industrial opportunities.
Once 3GPP 5G compatible satellite products are available the customer will benefit from a global eco systems and a multi-vendor supply chain
This two year projects started on January 2018. Project objectives will be refined after each 3GPP plenaries on a quarterly basis
The project has established a SSIG which gathers 38 participants (Airbus, Avanti, CNES, CTTC, Dish, DLR, ESA, Echostar, ESOA, ETRI, Eutelsat, Fraunhofer IIS, Fraunhofer Fokus, Gilat, iDirect, Hispasat, HNS, Inmarsat, Intelsat, Ligado, MERCE, Newtec, NICT, Nomor Research, Satellite Application Catapult, Satixfy, SES, SnT, STMicroelectronics, Univ Luxembourg, Telesat, Telespazio, Thales Alenia Space, TNO, Univ Bologna, Univ Roma, University of Surrey, Univ Napoli, VTT Technical Research Centre of Finland) of which 28 are 3GPP members.
This group has promoted successfully 3 study/work items to have satellite being addressed as part of the 3GPP release 16 (5G system phase 2 standardisation):
Every quarter, the progress of these 3 items will be monitored and reported to the 3GPP Plenaries and their prioritisation may be revisited against other terrestrial study items. It is therefore of the outmost importance that the satellite community contributes to the SSIG and participates to the 3GPP working group meetings.
Besides, the project has supported the preparation/review of more than 100 contributions in SA1 and RAN/RAN1 as part of the 3GPP release 15 (5G system phase 1 standardisation) for the completion of two Technical Reports:
Last, the project facilitates the review among satellite industry stakeholders of the ETSI 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”
