METHOD AND DEVICE FOR PERFORMING SIDELINK COMMUNICATION IN UNLICENSED BAND

Document Type and Number:

WIPO Patent Application WO/2024/063630

Kind Code:

A1

Abstract:

Provided are a method performed by a first device in a wireless communication system, and a device supporting same. The method may comprise the steps of: acquiring configuration information related to a physical sidelink feedback channel (PSFCH); acquiring information related to a first maximum number of discontinuous transmissions (DTXs) for sidelink (SL) radio link failure (RLF) detection; acquiring information related to a second maximum number of DTXs for SL RLF detection in an unlicensed band; transmitting, 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 via the PSSCH; increasing the number of DTXs by 1 on the basis of failing to receive a PSFCH in a PSFCH reception occasion associated with the PSSCH; and detecting a SL RLF on the basis that the number of DTXs reaches the first maximum number of DTXs or the second maximum number of DTXs. For example, the information related to the second maximum number of DTXs may be configured independently from the information related to the first maximum number of DTXs.
