Claim 13:
14. A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause a wireless user device to:
receive, from a first serving cell and via a first Physical Downlink Control Channel (PDCCH) in a first subframe, a first downlink grant comprising a first accumulated downlink assignment indicator (A-DAI) field and a first total DAI (T-DAI) field;
receive, from a second serving cell and via a second PDCCH in the first subframe, a second downlink grant comprising a second A-DAI field and a second T-DAI field;
receive, from a third serving cell and via a third PDCCH in a second subframe, a third downlink grant comprising a third A-DAI field and a third T-DAI field;
receive, from a fourth serving cell and via a fourth PDCCH in the second subframe, a fourth downlink grant comprising a fourth A-DAI field and a fourth T-DAI field;
determine a value of the first A-DAI field and a value of the first T-DAI field, wherein the value of the first T-DAI field indicates an integer T1, and wherein the value of the first A-DAI field indicates an integer A smaller than or equal to the integer T1;
determine a value of the second A-DAI field and a value of the second T-DAI field, wherein the value of the second T-DAI field indicates the integer T1, and wherein the value of the second A-DAI field indicates an integer B smaller than or equal to the integer T1;
determine a value of the third A-DAI field and a value of the third T-DAI field, wherein the value of the third T-DAI field indicates an integer T2, and wherein the value of the third A-DAI field indicates an integer C larger than the integer T1 and smaller than or equal to the integer T2;
determine a value of the fourth A-DAI field and a value of the fourth T-DAI field, wherein the value of the fourth T-DAI field indicates the integer T2, and wherein the value of the fourth A-DAI field indicates an integer D larger than the integer T1 and smaller than or equal to the integer T2
receive a first PDSCH indicated by the first PDCCH and receive a second PDSCH indicated by the second PDCCH;
receive an uplink grant indicating a transmission of a Physical Uplink Shared Channel (PUSCH);
determine a size of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook to which an HARQ-ACK associated with the first PDSCH and an HARQ-ACK associated with the second PDSCH are to be mapped; and
transmit, via the PUSCH, the HARQ-ACK associated with the first PDSCH and the HARQ-ACK associated with the second PDSCH,
wherein the first T-DAI field and the second T-DAI field indicate that total T1 number of downlink channels, comprising PDSCHs indicated by PDCCHs and comprising PDCCH indicating downlink semi persistent scheduling (SPS) release, are scheduled for the wireless user device in the first subframe, and
wherein PDCCHs comprising values of A-DAI and T-DAI are transmitted, in the first subframe, from total T1 number of different serving cells.
