1. A method for a relay User Equipment (UE), comprising:
the relay UE establishes a first PC5 Radio Resource Control (RRC) connection with a source remote UE and establishes a second PC5 RRC connection with a target remote UE;
the relay UE receives a PC5 Quality of Service (QoS) flow-to-Sidelink Radio Bearer (SLRB) mapping from the source remote UE after the first PC5 RRC connection between the relay UE and the source remote UE has been established, wherein the PC5 QoS flow-to-SLRB mapping includes a configuration index of an End-to-End (E2E) SLRB and at least one sidelink QoS flow identity (ID);
the relay UE transmits a configuration of a PC5 Relay Radio Link Control (RLC) channel to the target remote UE after the second PC5 RRC connection between the relay UE and the target remote UE has been established, wherein the E2E SLRB is associated with the PC5 Relay RLC channel;
the relay UE receives first information, indicating release of the PC5 QoS flow-to-SLRB mapping, from the source remote UE; and
the relay UE transmits second information, indicating release of the PC5 Relay RLC channel, to the target remote UE when there is no other E2E SLRB associated with the PC5 Relay RLC channel.
