Abstract
Methods and apparatus for beam failure recovery in a wireless communication system. A method of operating a user equipment (UE) is includes receiving, in a radio resource control (RRC) signaling, a pool of one or more reference signal (RS) resource indexes for a beam failure detection RS (BFD-RS) configuration; receiving a medium access control control element (MAC CE) command for BFD-RS activation; and receiving a control resource set (CORESET) with one or two transmission configuration information (TCI) states. The method further includes determining, based on the MAC CE command, a first set of one or more RS resource indexes for beam failure detection and determining, based on the one or two TCI states for the CORESET, one or more RS resource indexes in a second set of one or more RS resource indexes for beam failure detection.
