METHOD AND APPARATUS FOR PERFORMING CHANNEL ACCESS FOR PSFCH TRANSMISSION IN UNLICENSED BAND

Title:

METHOD AND APPARATUS FOR PERFORMING CHANNEL ACCESS FOR PSFCH TRANSMISSION IN UNLICENSED BAND

Document Type and Number:

WIPO Patent Application WO/2024/035154

Kind Code:

A1

Abstract:

A method for performing wireless communication by a first device, and an apparatus supporting same are provided. The method may comprise the steps of: receiving information related to channel occupancy time (COT) from a second device; receiving a first physical sidelink shared channel (PSSCH) from the second device; determining a first PSFCH resource for first physical sidelink feedback channel (PSFCH) transmission related to the first PSSCH; and performing second-type channel access for the first PSFCH transmission within the COT.
