Claim 0:
1. A method of reporting, by a user equipment (UE), hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information in a wireless communication system, the method comprising:
receiving i) a first Physical Downlink Control Channel (PDCCH) based on a first control resource set (CORESET) and ii) a second PDCCH based on a second CORESET;
receiving i) a first Physical Downlink Shared Channel (PDSCH) scheduled based on the first PDCCH and ii) a second PDSCH scheduled based on the second PDCCH; and
reporting the HARQ-ACK information related to the first PDSCH and the second PDSCH, based on a Physical Uplink Control Channel (PUCCH),
wherein, based on an index of a first CORESET group for the first CORESET and an index of a second CORESET group for the second CORESET being based on different values:
i) a first HARQ-ACK codebook related to the first CORESET group and ii) a second HARQ-ACK codebook related to the second CORESET group are separately generated,
a priority index associated with one of the first HARQ-ACK codebook and the second HARQ-ACK codebook is higher than a priority index associated with remaining one of the first HARQ-ACK codebook and the second HARQ-ACK codebook, and
the HARQ-ACK information is reported based on the first HARQ-ACK codebook and the second HARQ-ACK codebook.
