US Patent 12107654 Beam recovery techniques in beamformed wireless communications

Methods, systems, and devices for wireless communications are described that provide for measurement and recovery of beamformed transmission beams in which an uplink beam and a downlink beam may be decoupled beams that use different beamforming parameters. In the event that a user equipment (UE) detects a failure of the downlink beam, an indication may be provided to a base station, and the downlink beam may be switched to correspond to the uplink beam. In the event that the UE detects a failure of the uplink beam the UE may identify a candidate beam and transmit a beam recovery message to the base station. The downlink beam may have an associated first set of reference signals, and the uplink beam may have an associated second set of reference signals, and beam failure may be determined based on the different sets of reference signals.
