Abstract: Methods, systems, and devices for wireless communications are described. One method may include receiving, by a user equipment (UE) in a downlink shared data channel, a beam switch command instructing the UE to switch from a first uplink control beam to a second uplink control beam. The UE may select an uplink control beam to transmit acknowledgment feedback based on whether decoding the beam switch command is successful, and transmit, in an uplink control channel via the selected uplink control beam, the acknowledgment feedback indicating whether decoding the beam switch command was successful.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a signal identifying a first beam configuration and a second beam configuration to be used for performing a beamformed transmission of a physical uplink control channel (PUCCH) signal. The UE may determine, for a first PUCCH transmission occasion associated with the first beam configuration, that a communication metric associated with performing the beamformed transmission of the PUCCH signal using the first beam configuration fails to satisfy a threshold. The UE may perform, at a second PUCCH transmission occasion and based at least in part on the determining, the beamformed transmission of the PUCCH signal according to the second beam configuration.
