  • Patent number: 11172385
    Abstract: Apparatuses, methods, and systems are disclosed for the handling of beam failure. One apparatus includes a processor and a transceiver that that communicates with a base unit using a first set of beams. The processor detects beam failure for each beam in the first set of beams and initiates both a beam revival procedure and a beam recovery procedure in parallel. The processor terminates the beam recovery procedure in response to successful beam revival and prior to receiving a beam failure recovery response from the base unit. Additionally, the processor re-starts communication with the base unit using the first set of beams in response to successful beam revival.
