Claim 21:
22. A method of wireless communication operable by a base station (BS), the method comprising:
transmitting to a user equipment (UE) 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;
transmitting K downlink transmissions forming a downlink message to the UE, wherein K is greater than N;
receiving, as feedback information, N-M bits of compressed feedback information for K-M of the K downlink transmissions and M bits of uncompressed feedback information for M of the K downlink transmissions, the M bits transmitted using an unbundled HARQ-ACK codebook;
wherein the N-M bits of compressed feedback information is a first portion of the feedback information in compressed form and indicates whether a first portion of the downlink message was successfully decoded by the UE; and
wherein the M bits of uncompressed feedback information is a second portion of the feedback information and indicates whether a second portion of the downlink message that differs from the first portion of the downlink message was successfully decoded by the UE.
