Abstract: A method of a second user equipment (UE) for receiving sidelink data in a wireless communication system comprises receiving configuration information related to a resource pool for sidelink communication from a base station, receiving sidelink control information (SCI) from a first UE, and receiving the sidelink data from the first UE based on the SCI. The SCI is received based on a monitoring related to the SCI. Based on a slot in which the SCI is received, an active time related to sidelink (SL) discontinuous reception (DRX) is determined. Based on a resource pool including the slot in which the SCI is received, whether to perform an operation related to the SL DRX is determined.
