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.
