For claim 1, WANG teaches a hybrid automatic repeat request acknowledgement (HARQ-ACK) transmission method, comprising:
receiving, by a terminal, scheduling information sent by a network-side device (WANG, Fig. 5 step 504 and paragraph 210 teach the UE receives a first DCI format that schedules a first PDSCH and a second DCI format that schedules a second PDSCH.); and
in a case that the terminal determines, based on the scheduling information, that a first HARQ-ACK is triggered and that a second HARQ-ACK and the first HARQ-ACK are fed back within a same time unit, feeding back, by the terminal, the first HARQ-ACK and/or the second HARQ-ACK to the network-side device, wherein the second HARQ-ACK is a HARQ-ACK of one or more physical downlink shared channels (PDSCHs) and/or physical downlink control channels (PDCCHs) (WANG, Fig. 5 steps 506-508 and paragraph 210 teach in action 506, the UE determines a first PUCCH for a first HARQ-ACK codebook corresponding to the first PDSCH according to the first PUCCH resource configuration and determines a second PUCCH for a second HARQ-ACK codebook corresponding to the second PDSCH according to the second PUCCH resource configuration.

Upon receiving the triggering DCI, the UE shall transmit the HARQ-ACK information bits for all HARQ processes in one HARQ-ACK codebook. In this way, not only the postponed HARQ-ACK feedback for PDSCHs in the earlier COT or current COT can be triggered for transmission, but also the previous HARQ-ACK feedback which are not transmitted due to LBT failure at UE side or not correctly received at gNB side due to burst interference can be triggered for retransmission.).

For claim 17, WANG and Lei further teach the HARQ-ACK transmission method according to claim 15, wherein a first target PUCCH comprises a second PUCCH and a third PUCCH, wherein the second PUCCH is used to feed back the first HARQ-ACK, and the third PUCCH is used to feed back the second HARQ-ACK (WANG, Fig. 5 steps 506-508 and paragraph 210 teach in action 506, the UE determines a first PUCCH for a first HARQ-ACK codebook corresponding to the first PDSCH according to the first PUCCH resource configuration and determines a second PUCCH for a second HARQ-ACK codebook corresponding to the second PDSCH according to the second PUCCH resource configuration. In action 508, the UE transmits the first PUCCH when the first PUCCH overlaps the second PUCCH in a time domain, the first HARQ-ACK codebook and the second HARQ-ACK codebook multiplexed in the first PUCCH. Lei, Fig. 10 and paragraph 92 teach in step 1002, for each of the plurality of DL HARQ processes, the UE generates the HARQ-ACK feedback based on associated NDI bit and HARQ-ACK information bit. In step 1003, the UE transmits, to the BS, a HARQ-ACK codebook including the HARQ-ACK feedback for each of the plurality of DL HARQ processes. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method taught in WANG with Lei to have wherein a first target PUCCH comprises a second PUCCH and a third PUCCH, wherein the second PUCCH is used to feed back the first HARQ-ACK, and the third PUCCH is used to feed back the second HARQ-ACK. The motivation to combine is to improve the transmission efficiency.).
For claim 18, WANG and Lei further teach the HARQ-ACK transmission method according to claim 15, wherein the first HARQ-ACK is retransmission of the historical HARQ-ACK before the network-side device receives the first HARQ-ACK and/or the second HARQ-ACK (WANG, Fig. 5 steps 506-508 and paragraph 210 teach in action 506, the UE determines a first PUCCH for a first HARQ-ACK codebook corresponding to the first PDSCH according to the first PUCCH resource configuration and determines a second PUCCH for a second HARQ-ACK codebook corresponding to the second PDSCH according to the second PUCCH resource configuration. In action 508, the UE transmits the first PUCCH when the first PUCCH overlaps the second PUCCH in a time domain, the first HARQ-ACK codebook and the second HARQ-ACK codebook multiplexed in the first PUCCH. Lei, Fig. 10 and paragraph 92 teach in step 1002, for each of the plurality of DL HARQ processes, the UE generates the HARQ-ACK feedback based on associated NDI bit and HARQ-ACK information bit. In step 1003, the UE transmits, to the BS, a HARQ-ACK codebook including the HARQ-ACK feedback for each of the plurality of DL HARQ processes. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method taught in WANG with Lei to have wherein the first HARQ-ACK is retransmission of the historical HARQ-ACK before the network-side device receives the first HARQ-ACK and/or the second HARQ-ACK. The motivation to combine is to improve the transmission efficiency.).
For claim 19, WANG and Lei further teach the HARQ-ACK transmission method according to claim 15, wherein the scheduling information comprises a first information field, and the first information field is used to instruct to trigger retransmission of the historical HARQ-ACK corresponding to a target priority; or
the scheduling information comprises a second information field, and the second information field is used to indicate a priority of the first HARQ-ACK (WANG, Fig. 1 paragraph 34 teach the UE generates two HARQ-ACK codebooks, a first HARQ-ACK codebook is associated with a PUCCH of priority index 0 (e.g., low priority) and a second HARQ-ACK codebook is associated with a PUCCH of priority index 1 (e.g., high priority). Lei, Fig. 10 and paragraph 92 teach in step 1002, for each of the plurality of DL HARQ processes, the UE generates the HARQ-ACK feedback based on associated NDI bit and HARQ-ACK information bit. In step 1003, the UE transmits, to the BS, a HARQ-ACK codebook including the HARQ-ACK feedback for each of the plurality of DL HARQ processes. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method taught in WANG with Lei to have wherein the scheduling information comprises a first information field, and the first information field is used to instruct to trigger retransmission of the historical HARQ-ACK corresponding to a target priority; or the scheduling information comprises a second information field, and the second information field is used to indicate a priority of the first HARQ-ACK. The motivation to combine is to improve the transmission efficiency.).
For claim 20, WANG teaches a terminal (WANG, Fig. 5), comprising a processor (WANG, Fig. 5 item 626), a memory (WANG, Fig. 5 item 628), and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, causes the terminal to perform:
receiving scheduling information sent by a network-side device (WANG, Fig. 5 step 504 and paragraph 210 teach the UE receives a first DCI format that schedules a first PDSCH and a second DCI format that schedules a second PDSCH.); and
in a case that the terminal determines, based on the scheduling information, that a first HARQ-ACK is triggered and that a second HARQ-ACK and the first HARQ-ACK are fed back within a same time unit, feeding back the first HARQ-ACK and/or the second HARQ-ACK to the network-side device, wherein the second HARQ-ACK is a first feedback of a HARQ-ACK of one or more physical downlink shared channels (PDSCHs) and/or physical downlink control channels (PDCCHs) (WANG, Fig. 5 steps 506-508 and paragraph 210 teach in action 506, the UE determines a first PUCCH for a first HARQ-ACK codebook corresponding to the first PDSCH according to the first PUCCH resource configuration and determines a second PUCCH for a second HARQ-ACK codebook corresponding to the second PDSCH according to the second PUCCH resource configuration. In action 508, the UE transmits the first PUCCH when the first PUCCH overlaps the second PUCCH in a time domain, the first HARQ-ACK codebook and the second HARQ-ACK codebook multiplexed in the first PUCCH.),
Lei further teaches retransmission of a historical HARQ-ACK (Lei, Fig. 10 and paragraph 41 teach the main intention is to use one DCI to trigger the HARQ-ACK feedback for all the configured downlink HARQ processes. Upon receiving the triggering DCI, the UE shall transmit the HARQ-ACK information bits for all HARQ processes in one HARQ-ACK codebook. In this way, not only the postponed HARQ-ACK feedback for PDSCHs in the earlier COT or current COT can be triggered for transmission, but also the previous HARQ-ACK feedback which are not transmitted due to LBT failure at UE side or not correctly received at gNB side due to burst interference can be triggered for retransmission.).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method taught in WANG with retransmission of a historical HARQ-ACK taught in Lei to have method of receiving, by a terminal, scheduling information sent by a network-side device; and in a case that the terminal determines, based on the scheduling information, that a first HARQ-ACK is triggered and that a second HARQ-ACK and the first HARQ-ACK are fed back within a same time unit, feeding back, by the terminal, the first HARQ-ACK and/or the second HARQ-ACK to the network-side device, wherein the second HARQ-ACK is a first feedback of a HARQ-ACK of one or more physical downlink shared channels (PDSCHs) and/or physical downlink control channels (PDCCHs), and the first HARQ-ACK comprises retransmission of a historical HARQ-ACK. Because both WANG and Lei teach HARQ-ACK transmission method, Lei explicitly teach retransmission of a historical HARQ-ACK to improve the transmission efficiency.
