Title:
METHOD FOR TRANSMITTING AND RECEIVING SIDELINK DATA IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/090938
Kind Code:
A1
Abstract:
A method by which first user equipment performs sidelink communication in a wireless communication system, according to an embodiment of the present specification, comprises the steps of: generating a sidelink grant related to a resource allocation mode 2; transmitting a PSCCH to second user equipment; and transmitting a PSSCH to the second user equipment. 1) The second user equipment operates on the basis of a sidelink discontinuous reception (SL DRX) configuration, and 2) on the basis that at least one time duration related to the PSCCH for transmission of a medium access control protocol data unit (MAC PDU) based on the sidelink grant and second stage SCI related to the PSSCH are not in an SL DRX active time of the second user equipment, reselection of a resource based on the resource allocation mode 2 is triggered.
