Title:
METHOD AND DEVICE FOR PERFORMING SIDELINK COMMUNICATION IN UNLICENSED BAND
Document Type and Number:
WIPO Patent Application WO/2024/080677
Kind Code:
A1
Abstract:
Provided are a method performed by a first device in a wireless communication system, and a device supporting same. The method may comprise the steps of: obtaining configuration information related to a resource pool; obtaining configuration information related to sidelink (SL) listen before talk (LBT) failure recovery, including information related to the maximum number of SL LBT failures; performing LBT before SL transmission on a resource block (RB) set in the resource pool; increasing an LBT counter by 1 on the basis of the SL transmission not being performed; triggering a consistent SL LBT failure on the basis of the LBT counter reaching the maximum number of SL LBT failures; and on the basis of the triggered consistent SL LBT failure, transmitting information related to the consistent SL LBT failure to a base station, and releasing a sidelink grant related to the consistent SL LBT failure.
