Title:
METHOD AND APPARATUS FOR PERFORMING SIDELINK COMMUNICATION IN UNLICENSED BAND
Document Type and Number:
WIPO Patent Application WO/2024/071893
Kind Code:
A1
Abstract:
A method by which a terminal performs sidelink communication on the basis of an unlicensed band in a wireless communication system, may comprise the steps of: receiving, by the terminal from a base station, sidelink resource pool configuration information on the basis of higher layer signaling; generating SL grant if data is generated in LCH on the basis of the sidelink resource pool configuration information; selecting a slidelink resource pool according to whether HARQ feedback is configured in the data generated in the LCH on the basis of the sidelink resource pool configuration information; and performing sidelink transmission by selecting a sidelink transmission resource from the selected sidelink resource pool.
