1. A method for wireless communication at a user equipment (UE), comprising:
receiving a plurality of downlink control information messages scheduling a plurality of downlink data channels, the plurality of downlink control information messages including at least a first downlink control information message and a second downlink control information message, the first downlink control information message scheduling a first downlink data channel of a first component carrier and a second downlink data channel of a second component carrier, and the second downlink control information message scheduling a third downlink data channel;
identifying a set of downlink assignment indices in the received plurality of downlink control information messages, each downlink control information message of the plurality of downlink control information messages including a unique downlink assignment index of the set of downlink assignment indices;
generating a set of feedback bits of an acknowledgement codebook, the set of feedback bits including a same number of feedback bits for each downlink assignment index of the set of downlink assignment indices, wherein the set of feedback bits are ordered within the acknowledgement codebook based at least in part on a control channel occasion associated with each respective downlink control information message of the plurality of downlink control information messages; and
transmitting the generated set of feedback bits on an uplink control channel.
