A 5G-MAG pre-alignment workshop on Non-Terrestrial Networks (NTN) and content delivery, ahead of the Rel-19 package decisions at the December 2023 3GPP TSG #102 SA and RAN plenaries.
| Event | 5G-MAG Workshop |
| Date | Tuesday 28 November 2023, 15:00 - 17:00 CET |
| Location | Online |
This workshop focused on discussions relevant to the Rel-19 package decisions for the upcoming 3GPP TSG #102 SA and RAN plenaries, in relation to 5G-MAG's input as a Market Representation Partner (MRP) to the 3GPP workshops organized at RAN and SA.
Agenda
Potential topics in scope for the session included:
- Study of NTN enhancements to support NGSO mobile base stations and broadcast to a specific geographical area, addressing the discrepancy with beam footprints
- NTN enhancements to support multicast in connected mode in NGSO, addressing mobility issues including hand-over in particular
- NTN enhancements on HARQ feedback/retransmission, applicable to both PTP and PTM transmission
- NTN enhancements to support multicast over a downlink-only NTN combined with a terrestrial network cell
- Study of the need for architectural enhancements for 5G multicast-broadcast services via NTN
- Enhancements to support multicast/broadcast over a downlink-only NTN and support for a heterogeneous return path (3GPP or non-3GPP access)
- Study of necessary architectural enhancements for 5G MBS via NTN
Topics were drawn from 5G-MAG's Members' Views on Standards.
Note
This 2023 session pre-dates and is distinct from the April 2026 webinar on NTN & Content Delivery, which revisits the topic in light of later Rel-19 progress.
