1. A method for a relay user equipment (UE) comprising:
configuring a layer-2 (L2)-based sidelink (SL) relay path with the relay UE being a relay node between a remote UE and a gNB in a new radio (NR) wireless network, wherein the L2-based relay path includes one or more relay nodes;
establishing one or more sidelink relay channels with the remote UE by the relay UE;
activating an end-to-end sidelink relay data channel based on the configured L2-based SL relay path; and
performing bearer mappings, by the relay UE, for traffic forwarding between the remote UE and the gNB based on the configured L2-based SL relay path, wherein the bearer mapping associates an end-to-end Uu bearer ID of the end-to-end sidelink relay data channel with a relay channel ID.
