Abstract
Apparatus and methods are provided for sidelink configuration and traffic forwarding for L2 UE-to-UE relay. In one novel aspect, the relay UE configures sidelink configuration for both direct PC5 link between the relay UE and the remote UE and indirect PC5 link between two remote UEs. The relay UE performs traffic forwarding for remote UEs based on the adaptation information included within the SL-SCH sub-header of PC5 MAC sub-PDU. In one embodiment, the UE establishes sidelinks, configures end-to-end SLRB, activates the end-to-end SLRB, and forwards data packets between the remote UEs based on bearer mapping. The end-to-end SLRBs are activated automatically or are activated by a PC5 MAC control element (CE) or RRC message between the remote UEs. In another embodiment, the bearer mapping correlates the end-to-end SLRB ID with a plurality of sidelink relay channel IDs.
