Title:
METHOD AND APPARATUS FOR DETECTING AND RECOVERING OF BEAM FAILURE
Document Type and Number:
WIPO Patent Application WO/2023/055169
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Methods and apparatuses for beam failure detection in a wireless communication system. A method for operating a user equipment (UE) includes receiving downlink control information (DCI) including a first TCI field indicating a first transmission configuration indication (TCI) state; receiving information about a type of the first TCI state; and determining, based on the first TCI state and the type of the first TCI state, a first set of beam failure detection (BFD) reference signal (RS) resource configuration indexes. The type of the first TCI state is a joint TCI state indicated by a DLorJointTCIState parameter, a separate downlink (DL) TCI state indicated by a DLorJointTCIState parameter, or a separate UL TCI state indicated by a UL-TCIState parameter. The BFD RS resource configuration indexes correspond to periodic CSI-RS resource configuration indexes.
