Uplink control channel beam switch procedure

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.
