Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A wireless communication device operable as a base station (BS), 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:
transmit to a user equipment (UE), 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 Nis greater than M;
transmit K downlink transmissions forming a downlink message to the UE via the one or more transceivers, wherein K is greater than N; and
receive, 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, via the one or more transceivers;
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.
