Title:
METHOD AND APPARATUS FOR PERFORMING BEAM RECOVERY IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/003352
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for performing beam recovery in a wireless communication system. A method for performing beam failure recovery (BFR) in a wireless communication system, according to an embodiment of the present disclosure, may comprise the steps of: identifying a first control resource set (CORESET) pool and a second CORESET pool, on the basis of configuration information; on the basis that beam failure regarding a spatial parameter associated with the first CORESET pool is detected, transmitting a physical random access channel (PRACH) for the BFR, on the basis of a spatial parameter associated with the second CORESET pool; receiving a response regarding the PRACH, on the basis of the spatial parameter associated with the second CORESET; transmitting MAC-CE for the BFR, on the basis of the spatial parameter associated with the second CORESET pool; and receiving a response regarding the MAC-CE, on the basis of the spatial parameter associated with the second CORESET pool.
