Title:

METHOD AND APPARATUS FOR PAIRING BEAMS IN WIRELESS COMMUNICATION SYSTEM SUPPORTING SIDELINK COMMUNICATION

Document Type and Number:

WIPO Patent Application WO/2023/243984

Kind Code:

A1

Abstract:

A method for a first user equipment (UE), according to the present disclosure, comprises the steps of: beam sweeping a first physical sidelink control channel (PSCCH) including beam identification information and physical sidelink feedback channel (PSFCH) resource information, and transmitting same to a second UE; receiving the PSFCH from the second UE on the basis of the PSFCH resource information; pairing beams by determining, on the basis of transmission beam indication information included in the received PSFCH and a beam by which the PSFCH is received, a transmission beam and a reception beam to be used for sidelink communication; and sidelink-communicating with the second UE through the paired beams.
