Title:
METHOD AND DEVICE FOR USER EQUIPMENT REPORTING SL HARQ-ACK INFORMATION IN UNLICENSED BAND
Document Type and Number:
WIPO Patent Application WO/2024/035187
Kind Code:
A1
Abstract:
Provided are a method for a first device carrying out wireless communication, and a device supporting same. The method may comprise the steps of: acquiring information related to a plurality of physical sidelink feedback channel (PSFCH) occasions; acquiring information related to a slot offset between PSFCH-physical uplink control channel (PUCCH); transmitting, to a second device via a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for scheduling second SCI and a physical sidelink shared channel (PSSCH); transmitting the second SCI and data to the second device via the PSSCH; generating HARQ feedback information for the plurality of PSFCH occasions; and reporting the HARQ feedback information to a base station on the basis of a PUCCH resource.
