Title:
METHOD AND APPARATUS FOR MANAGING LBT FAILURE WITH BEAM GROUP IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/132540
Kind Code:
A1
Abstract:
The present disclosure relates to a method for managing LBT (Listen before Talk) failure with a beam group in a wireless communication system. In particular, the method includes the steps of: receiving information related to a first beam group including a first beam and a at least one second beam; and performing a data transmission via the at least one second beam based on a Listen before talk (LBT) failure being detected for the first beam, wherein, based on the LBT failure being detected for both the first beam and the at least one second beam, a LBT failure recovery procedure for the first beam group is performed.
