Study on system enhancement for Proximity based Services (ProSe) in the 5G System (5GS); Phase 3
The present document will study and identify potential enhancements to the 5G Proximity-based Services (5G ProSe) system defined in TS 23.304 [4] (beyond what has been specified in Rel-17 and Rel-18) considering the services requirements defined in TS 22.278 [5], TS 22.261 [6] and TS 22.115 [7].
The study will investigate potential 5GS enhancements in the following areas:
- Enhance ProSe to support multi-hop over NR PC5 reference point for UE-to-Network Relay for Layer-2 and Layer-3 Relays.
- Enhance ProSe to support multi-hop over NR PC5 reference point for UE-UE Relay for Layer-3 Relays.
