1. A user equipment (UE), comprising:
one or more memories storing code; and
one or more processors coupled with the one or more memories and operable to execute the code to cause the UE to:
receive a feedback trigger for communication of hybrid automatic repeat request (HARQ) feedback, wherein a HARQ acknowledgement (ACK) codebook size associated with the HARQ feedback is based at least in part on a quantity of configured HARQ processes; and
communicate the HARQ feedback in accordance with the HARQ ACK codebook size in a shared radio frequency spectrum band, wherein the feedback trigger is included in a downlink control information (DCI) message that is separate from a downlink grant and an uplink grant.
