Abstract: A method for measuring beams includes determining a measurement period duration in accordance with periods of one or more periodic beam failure detection (BFD) reference signals (RSs) of a BFD RS set, wherein the BFD RSs of the one or more BFD RSs of the BFD RS set have a quasi-co-located (QCL) relationship with demodulation RSs (DMRSs) of PDCCH receptions monitored by a user equipment (UE), monitoring a subset of the one or more BFD RSs having the QCL relationship with the DMRSs of PDCCH receptions monitored by the UE that occur during a measurement period, and determining that measures of all BFD RSs in the subset of the one or more BFD RSs do not meet a specified threshold, and based thereon, reporting a beam failure (BF) instance.

Abstract: Embodiments of the present disclosure provide an apparatus and method for beam failure recovery between a UE and a base station operating in a discontinuous reception (DRX) mode. In an embodiment, the UE receives a frame from a base station for determining a radio link quality of a physical downlink control channel (PDCCH). The UE determines whether the frame is received only during the DRX ON state of the DRX mode and that the radio link quality of the PDCCH is less than an acceptable quality threshold. In response, the UE transmits a recovery message to the base station indicating a change to a communication beam used to receive the frame.
