1. A user equipment (UE) for wireless communication, comprising:
memory; and
one or more processors, coupled to the memory, configured to:
select uplink communication resources to be used to transmit enhanced uplink control information (UCI) to a network node based at least in part on a size of a hybrid automatic repeat request (HARQ) codebook and an enhancement number; and
transmit the enhanced UCI using the selected uplink communication resources, wherein the enhanced UCI comprises a set of feedback bits and a set of enhancement bits, the set of feedback bits comprising at least one negative acknowledgement (NACK) bit, wherein the set of enhancement bits indicate information associated with the at least one NACK bit, and wherein:
one or more of the set of enhancement bits are omitted from the enhanced UCI during transmission of the enhanced UCI when a quantity of enhancement bits of the set of enhancement bits is greater than the enhancement number, or
the set of enhancement bits are transmitted using rate-matching based at least in part on the set of feedback bits when the quantity of enhancement bits of the set of enhancement bits is less than the enhancement number.
