METHOD AND DEVICE FOR DETERMINING MULTIPLE CANDIDATE TRANSMISSION TIME POINTS WITHIN SLOT IN UNLICENSED BAND

Title:

METHOD AND DEVICE FOR DETERMINING MULTIPLE CANDIDATE TRANSMISSION TIME POINTS WITHIN SLOT IN UNLICENSED BAND

Document Type and Number:

WIPO Patent Application WO/2024/072169

Kind Code:

A1

Abstract:

An operation method of a first device (100) in a wireless communication system is proposed. The method may comprise the steps of: acquiring information on a first candidate start symbol and a second candidate start symbol; with respect to the first candidate start symbol, performing first channel sensing for a channel access procedure (CAP); and on the basis of a first slot, performing physical sidelink shared channel (PSSCH) transmission to a second device.
