1. A method for wireless communications by a user equipment (UE), comprising:
obtaining a configuration, from a downlink control information (DCI) in a first signal from a base station (BS), comprising at least one first pattern of beams to monitor when performing a beam recovery procedure;
sending a first acknowledgment of the DCI to the BS;
communicating using beamforming, with the BS, via an active transmit and receive beam pair;
determining a beam failure of the active transmit and receive beam pair; and
monitoring the beams according to the first pattern in response to determining the beam failure.
