1. A wireless communication device operable as user equipment (a UE), comprising:
one or more processors;
one or more transceivers coupled to the one or more processors; and
one or more memories coupled to the one or more processors, wherein the one or more processors are individually or collectively configured to cause the wireless communication device to:
receive, via the one or more transceivers, an unbundled hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook size M and a maximum HARQ-ACK codebook size N, wherein N is greater than M;
receive, via the one or more transceivers, K downlink transmissions forming a downlink message, wherein K is greater than N;
transmit, via the one or more transceivers, N-M bits of compressed feedback information for K-M of the K downlink transmissions, wherein the compressed feedback information that is a first portion of feedback information in compressed form, the feedback information indicating whether the K downlink transmissions were successfully decoded by the UE; and
transmit, via the one or more transceivers, M bits of uncompressed feedback information for M of the K downlink transmissions using an unbundled HARQ-ACK codebook, wherein the uncompressed feedback information is a second portion of the feedback information that is different from the first portion of the feedback information.
