1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, a system information block (SIB) for a sidelink communication, wherein the received SIB includes an area scope parameter;
determining a validity of a stored SIB for a sidelink communication, based on the received SIB, wherein the stored SIB is determined as invalid in case that a value of an area scope parameter associated with the stored SIB is not the same as a value of the area scope parameter in the received SIB;
in case that the stored SIB is determined as invalid, receiving, from the base station, system information including resource configuration information for the sidelink communication; and
autonomously determining a sidelink resource, based on the resource configuration information in case that the UE is inside a coverage area of the base station,
wherein the sidelink resource is determined based on preconfigured resource information in case that the UE is outside the coverage area of the base station.
