Abstract
A method executed by a relay UE is provided. The relay UE establishes a first Radio Link Control (RLC) channel between a first remote UE and the relay UE, in which the first RLC channel is associated with a first end-to-end identifier. The relay UE establishes a second RLC channel between a second remote UE and the relay UE, in which the second RLC channel is associated with the first end-to-end identifier or a second end-to-end identifier. The relay UE receives an incoming SideLink (SL) transmission from the first remote UE on the first RLC channel, in which the incoming SL transmission includes the first end-to-end identifier. The relay UE sends an outgoing SL transmission to the second remote UE on the second RLC channel, in which the outgoing SL transmission includes one of the first end-to-end identifier and the second end-to-end identifier.
