Claim of US Patent No. 10,602,555

1. A method for a User Equipment (UE) operating in a wireless communication system, the method comprising:receiving a configuration information index of a configuration information set via a sidelink from the peer UE, wherein the UE is directly connected to the peer UE via the sidelink and, wherein the configuration information set corresponds to a sidelink radio bearer to be configured;
configuring the sidelink radio bearer according to the configuration information set indicated by the configuration information index;
establishing Radio Link Control (RLC) and Packet Data Convergence Protocol (PDCP) entities for the sidelink radio bearer based on the configuration information index of the configuration information set, wherein the configuration information set includes at least one parameter including a PDCP-SN-Size, a headerCompression, a SN-FieldLength and a T-Reordering; and
updating the RLC and PDCP entities for the sidelink radio bearer, when values of the PDCP-SN-Size, the headerCompression, the SN-FieldLength, and the T-Reordering are set to values in the configuration information set indicated by the configuration information index.
