Abstract
Apparatus and methods are provided for connection establishment and bearer mapping for L2-based sidelink UE-to-Network relay. In one novel aspect, the connection establishment is triggered by a Uu RRC message or a PC5 RRC message of the Sidelink Relay Channel Configuration Request. In one embodiment, the establishing of one or more sidelink relay channels is triggered by a resource control (RRC) message of Sidelink Relay Channel Configuration Request. In one embodiment, the relay UE sends a PC5 RRC message of Sidelink Relay Channel Configuration Request to the remote UE based on a Uu RRC message from the gNB. In another embodiment, the relay UE sends a sidelink UE information (SUI) to the gNB with UE information for the relay and remote UEs. In another embodiment, the bearer mapping is based on a mapping between a relay channel ID and a Uu bearer ID of a mapped relay radio bearer.
