Claim 3:
4. A method for a second User Equipment (UE), comprising:
establishing a Sidelink (SL) Data Radio Bearer (DRB) for reception from a first UE directly or via a relay UE, wherein a configuration of the SL DRB is identified by a configuration index, and the SL DRB is mapped to a SL Radio Link Control (RLC) channel established between the first UE and the second UE or between the second UE and the relay UE, and wherein the SL RLC channel is identified by a logical channel identity (LCID);
deciphering, using at least the LCID as input to deciphering algorithm, a sidelink packet received from the first UE on the SL DRB if the SL DRB is established for reception from the first UE directly; and
deciphering, using at least the configuration index as input to deciphering algorithm, the sidelink packet received from the first UE on the SL DRB if the SL DRB is established for reception from the first UE via the relay UE.
