Method for performing sidelink communication in unlicensed band by UE in wireless communication system and apparatus therefor

Abstract

Disclosed are a method of transmitting a signal in an unlicensed band in a wireless communication system for supporting sidelink communication and an apparatus therefor. The method includes randomly selecting a value of a back-off counter within a contention window related to an unlicensed band, and transmitting a first signal in the unlicensed band based on the back-off counter, wherein, based on that the first signal is a sidelink signal in which a Hybrid Automatic Repeat and request (HARQ) feedback is activated, a size of the contention window is updated based on a feedback signal including Acknowledgement (ACK) among feedback signals for the first signal received from a plurality of UEs.
