Method for transmitting and receiving harq information in wireless communication system, and device therefor

A processing apparatus configured to control a user equipment (UE) to report hybrid automatic repeat and request-acknowledgment (HARQ-ACK) information in a wireless communication system, the processing apparatus comprising:

• at least one processor;
• and
• at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• receiving a first physical downlink control channel (PDCCH) related to a first CORESET group;
• receiving a second PDCCH related to a second CORESET group;
• receiving a first physical downlink shared channel (PDSCH) based on the first PDCCH;
• receiving a second PDSCH based on the second PDCCH;
• generating (i) a first HARQ-ACK codebook for the first PDSCH and (ii) a second HARQ-ACK codebook for the second PDSCH separately;
• concatenating the first HARQ-ACK codebook followed by the second HARQ-ACK codebook;
• and
• reporting the HARQ-ACK information based on the concatenated HARQ-ACK codebook.

A computer-readable storage medium storing at least one instruction that, based on being executed by at least one processor, allows the at least one processor to:

• control to receive a first physical downlink control channel (PDCCH) related to a first CORESET group;
• control to receive a second PDCCH related to a second CORESET group;
• control to receive a first physical downlink shared channel (PDSCH) based on the first PDCCH;
• control to receive a second PDSCH based on the second PDCCH;
• generate (i) a first hybrid automatic repeat and request-acknowledgment (HARQ-ACK) codebook for the first PDSCH and (ii) a second HARQ-ACK codebook for the second PDSCH separately;
• concatenate the first HARQ-ACK codebook followed by the second HARQ-ACK codebook;
• and
• control to reporting HARQ-ACK information based on the concatenated HARQ-ACK codebook.
