Abstract:
A user equipment (UE) and a method for wireless communication are provided. The method includes receiving a first radio resource control (RRC) configuration, the first RRC configuration configuring a radio link monitoring configuration that includes a beam failure detection (BFD) timer and a beam failure indication (BFI) count threshold; starting or restarting the BFD timer by a medium access control (MAC) entity of the UE each time a BFI is received from a lower layer; counting a number of the received BFIs using a BFI counter; initiating a beam failure recovery (BFR) procedure upon determining that the BFI counter indicates a value greater than or equal to the BFI count threshold; and setting the BFI counter to zero when receiving a second RRC configuration that reconfigures the radio link monitoring configuration.
