1. A user equipment (UE) comprising:
a transceiver; and
a processor coupled to the transceiver, configured to:
receive, via the transceiver, one or more Channel State Information (CSI)-Reference Signals (RSs);
transmit, via the transceiver, Channel Quality Indicator (CQI) feedback corresponding to the one or more CSI-RSs received, wherein the CQI feedback is determined utilizing a time urgency type;
receive, via the transceiver, a single downlink control information (DCI) signal used to schedule multiple Physical Downlink Shared Channel (PDSCH) transmissions, wherein the multiple PDSCH transmissions are based at least on one modulation and coding scheme (MCS) corresponding to the CQI feedback;
construct a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) codebook based at least on the multiple PDSCH transmissions;
prune HARQ-ACK bits of the HARQ-ACK codebook;
allocate the pruned HARQ-ACK bits to X bundles, with M bits per bundle, where X and M are integers; and
perform an AND operation within a bundle of the X bundles.
