Title:
METHOD AND DEVICE FOR SELECTING RESOURCE IN CONSIDERATION OF PROCESSING TIME REQUIRED FOR CHANNEL ACCESS PROCEDURE IN UNLICENSED BAND
Document Type and Number:
WIPO Patent Application WO/2024/035205
Kind Code:
A1
Abstract:
A method of operating a first device (100) in a wireless communication system is proposed. The method may comprise the steps of: triggering resource selection; determining a resource selection window for the resource selection; determining a sensing window related to at least one candidate resource within the resource selection window; performing sensing on the sensing window; determining at least one idle resource among the at least one candidate resource on the basis of a result of the sensing; and selecting, from among the at least one idle resource, a transmission resource that is a resource reflecting a sensing section of channel sensing for a channel access procedure (CAP).
