Dynamic bundling for feedback

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

• transmitting, to a user equipment (UE), a downlink control information message comprising an indicator that dynamically indicates bundling of one or more feedback messages;
• transmitting, to the UE, a plurality of downlink data messages;
• and
• receiving, from the UE, a bundled feedback corresponding to a plurality of feedback messages for the plurality of downlink data messages based at least in part on bundling being enabled by the indicator, the bundled feedback comprising fewer feedback bits than a number of feedback bits included in the plurality of feedback messages.

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

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a base station, a downlink control information message comprising an indicator that dynamically indicates bundling of one or more feedback messages;
• determine, based at least in part on the indicator, a bundled feedback from a plurality of feedback messages corresponding to a plurality of downlink data messages, the bundled feedback comprising fewer feedback bits than a number of feedback bits included in the plurality of feedback messages;
• and
• transmit the bundled feedback based at least in part on bundling being enabled by the indicator.
