Feedback for beam changes

A method of wireless communication at a base station, comprising:

• transmitting, to a user equipment (UE), a downlink transmission on a downlink data channel including data and an indication of a beam switch;
• receiving first acknowledgement (ACK) feedback from the UE in response to transmitting the data;
• and
• receiving, on a same beam set as the first ACK feedback, second ACK feedback from the UE in response to transmitting the indication of the beam switch, the second ACK feedback being separate from the first ACK feedback.

An apparatus for wireless communication by a user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive, from a base station, a downlink transmission on a downlink data channel including data and an indication of a beam switch;
• transmit first acknowledgement (ACK) feedback to the base station in response to reception of the data;
• and
• transmit, on a same beam set as the first ACK feedback, second ACK feedback to the base station in response to reception of the indication of the beam switch, the second ACK feedback being separate from the first ACK feedback.
