Title:
MANAGING BEAM FAILURE RECOVERY UPDATES
Document Type and Number:
WIPO Patent Application WO/2021/237558
Kind Code:
A1
Abstract:
In various embodiments, methods that may be performed by a processor of a wireless device for managing beam failure recovery may include determining that a contention based random access (CBRA) -based beam failure recovery (BFR) procedure has been completed, determining whether a new candidate beam reference signal identifier was identified and included in a BFR media access control-control element (MAC-CE), updating beam information based on the new candidate beam reference signal identifier in response to determining that the new candidate beam reference signal identifier (RS ID) was identified and included in a BFR MAC-CE in a message to the base station, and updating the beam information based on a synchronization signal block selected during the CBRA-based BFR procedure in response to determining that the new candidate beam RS ID was not identified and included in the BFR MAC-CE in the message to the base station.
