Method and apparatus for determining hybrid automatic repeat request-acknowledgment harq-ack codebook, and terminal

A terminal, comprising a processor and a memory, wherein the memory stores a program or an instruction capable of running on the processor, wherein the program or instruction, when executed by the processor, causes the terminal to perform:

• determining a target HARQ-ACK codebook based on a HARQ-ACK codebook type and/or scenario type for a physical downlink channel;
• wherein
• the HARQ-ACK codebook type for the physical downlink channel comprises a type 1 HARQ-ACK codebook and a type 2 HARQ-ACK codebook;
• and
• the scenario type for the physical downlink channel comprises a first scenario and a second scenario, wherein the first scenario is that the terminal reports, on one PUCCH, only a HARQ-ACK corresponding to a specified physical downlink channel received within a candidate PDSCH reception occasion, and the second scenario is a scenario other than the first scenario.

A non-transitory readable storage medium, wherein the non-transitory readable storage medium stores a program or an instruction, wherein the program or instruction, when executed by a processor, causes the processor to perform:

• determining a target HARQ-ACK codebook based on a HARQ-ACK codebook type and/or scenario type for a physical downlink channel;
• wherein
• the HARQ-ACK codebook type for the physical downlink channel comprises a type 1 HARQ-ACK codebook and a type 2 HARQ-ACK codebook;
• and
• the scenario type for the physical downlink channel comprises a first scenario and a second scenario, wherein the first scenario is that the terminal reports, on one PUCCH, only a HARQ-ACK corresponding to a specified physical downlink channel received within a candidate PDSCH reception occasion, and the second scenario is a scenario other than the first scenario.
