Title:
METHOD FOR TRANSMITTING AND RECEIVING SIDELINK DATA AND DEVICE FOR SAME IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/033591
Kind Code:
A1
Abstract:
A method for a second terminal to receive sidelink data in a wireless communication system according to an embodiment disclosed herein comprises the steps of: receiving, from a base station, configuration information related to a resource pool for sidelink communication; receiving sidelink control information (SCI) from a first terminal; and receiving sidelink data from the first terminal on the basis of the SCI. The SCI is received on the basis of monitoring related to the SCI. An active time related to SL discontinuous reception (SL DRX) is determined on the basis of the slot in which the SCI was received. Whether to perform an operation related to the SL DRX is determined on the basis of a resource pool including the slot in which the SCI was received.
