Certain aspects of the present disclosure provide techniques for enhancing coverage while transmitting an acknowledgment (ACK) to a base station to acknowledge a beam change instruction. Such aspects of the present disclosure may increase the reliability of control information transmitted on a control channel by a user equipment (UE), such as ACK feedback transmitted on a physical uplink control channel by a UE to a base station. In certain aspects, a UE may receive, from a base station, information indicating a beam switch from a first beam via which the UE communicates with the base station to a second beam. The UE may further transmit, based on the information indicating the beam switch, two or more ACK messages to the base station on a control channel, and the two or more ACK messages may acknowledge receipt of the information indicating the beam switch from the base station.
