Title:
METHOD FOR A TRANSMISSION/RECEPTION POINT (TRP) SPECIFIC BEAM FAILURE RECOVERY (BFR) FOR A SINGLE DOWNLINK CONTROL INFORMATION (DCI) MODE
Document Type and Number:
WIPO Patent Application WO/2022/236708
Kind Code:
A1
Abstract:
Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a first transmission/reception point (TRP) and a second TRP and a processor communicatively coupled to the transceiver. The UE is in a multi-TRP mode. The processor is configured to perform a first beam failure detection (BFD) procedure for the first TRP and a second BFD procedure for the second TRP. The processor is further configured to perform a first beam failure recovery (BFR) procedure for the first TRP responsive to a result of the first BFD procedure and a second BFR for the second TRP responsive to a result of the second BFD procedure. The processor is further configured to receive a configuration message, a BFD configuration, and a BFR configuration. The UE switches to a single-TRP mode upon receiving the configuration message. The processor is further configured to update the first BFD procedure based on the BFD configuration and update the first BFR procedure based on the BFR configuration. Finally, the processor is configured to perform the updated first BFD procedure and the updated first BFR procedure for the first TRP responsive to a result of the updated first BFD procedure.
