Title:
METHOD AND DEVICE FOR PERFORMING SIDELINK COMMUNICATION IN UNLICENSED SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2024/063631
Kind Code:
A1
Abstract:
Provided are a method performed by a first device and a device supporting same in a wireless communication system. The method may comprise the steps of: acquiring a resource pool; selecting one or more resources from the resource pool; receiving first sidelink control information (SCI) for scheduling second SCI and a physical sidelink shared channel (PSSCH) from a second device through a physical sidelink control channel (PSCCH); receiving the second SCI including information related to a channel occupancy time (COT) duration from the second device through the PSSCH; and triggering resource reselection on the basis that at least one of the one or more resources is outside the COT duration.
