Title:
METHOD FOR CARRYING OUT CHANNEL ACCESS PROCEDURE, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/154406
Kind Code:
A1
Abstract:
The present disclosure discloses a method by which user equipment transmits an uplink signal in a wireless communication system. In particular, the method is characterized by: receiving first information related to an uplink (UL) transmission beam; determining a listen-before-talk (LBT) beam on the basis of the first information; and transmitting the uplink signal via the UL transmission beam, on the basis of LBT, which is based on the LBT beam, having succeeded.
