Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an uplink grant that includes multiple total downlink assignment indexes (DAIs) corresponding to multiple DAI groups associated with the UE, wherein each of the multiple DAI groups is associated with a different set of component carriers used by the UE for carrier aggregation; and transmit (ACK/NACK) feedback for the multiple DAI groups based at least in part on the multiple total DAIs included in the uplink grant. In some aspects, a base station may determine multiple total DAIs corresponding to multiple DAI groups associated with a UE, wherein each of the multiple DAI groups is associated with a different set of component carriers used by the UE for carrier aggregation; and transmit the multiple total DAIs to the UE in an uplink grant. Numerous other aspects are provided.
