1. A method for wireless communication at a user equipment (UE) in a shared radio frequency spectrum band, comprising:
receiving, at the UE, a feedback trigger for transmission 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 number of configured HARQ processes and a corresponding quantity of downlink channel monitoring occasions; and
transmitting the HARQ feedback in accordance with the HARQ ACK codebook size wherein the feedback trigger is embedded in a downlink control information (DCI) message, which is separate from a downlink grant and an uplink grant.
