Title:
METHOD AND APPARATUS FOR PERFORMING DRX OPERATION ON BASIS OF RESOURCE ALLOCATION INFORMATION IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2022/131732
Kind Code:
A1
Abstract:
Provided are a method by which a first apparatus performs wireless communication, and an apparatus for supporting same. The method may comprise the steps of: initiating a timer for an active time; receiving, from a second apparatus through a physical sidelink control channel (PSCCH) on the basis of a first sidelink (SL) resource, first sidelink control information (SCI) including information related to a time domain of a second SL resource and information related to a frequency domain of the second SL resource; receiving second SCI and data from the second apparatus through a physical sidelink shared channel (PSSCH) related to the PSCCH on the basis of the first SL resource; determining a value of an SL discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round trip time (RTT) timer, on the basis of a time interval between the first SL resource and the second SL resource; and initiating the SL DRX HARQ RTT timer.
