ALIX - Support to Standardisation of Satellite 5G Component

Objectives

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.

Challenges

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.

Benefits

Once 3GPP 5G compatible satellite products are available the customer will benefit from a global eco systems and a multi-vendor supply chain

Plan

This project started on January 2018 and has been extended until mid-2021 to cover 3GPP Release 17 ending September 2021. Project objectives are refined after each 3GPP plenaries on a quarterly basis

Current status

To have satellite included in the 5G roadmap of 3GPP, the ALIX consortium has carried out successfully the following 3GPP standardisation activities.

As part of the Release 15 (April 2017 – June 2018), it has led the development of

As part of the Release 16 (August 2018 – December 2019), it has led the development of

 As part of the Release 17 (Jan 2020 – September 2021), it will lead the development of change requests as part of

 Last, the project led the development in ETSI of

In addition, the project has established a Satellite Standardisation Interest Group (SSIG) which gathers 38 participants (Airbus, Avanti, CNES, CTTC, Dish, DLR, ESA, Echostar, ESOA, ETRI, Eutelsat, Fraunhofer IIS, Fraunhofer Fokus, Gilat, iDirect, IIT-Hyderabad, Hispasat, HNS, Inmarsat, Intelsat, Ligado, MERCE, NBN, Newtec, NICT, Nomor Research, Reliance Jio, 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 most are 3GPP members, The SSIG is a platform where a broad range of stakeholders exchange information about such satellite-related standards activities, with the aim of improving mutual understanding and thus focus and effectiveness. The SSIG may also provide a platform to garner support from individual participants for specific actions they wish to pursue.
