A method of transmitting, performed by a user equipment , UE, hybrid automatic repeat and reQuest-acknowledgement, HARQ-ACK, information in a wireless communication system, the method comprising: receiving (S1410) configuration information related to a plurality of control resource sets, wherein the configuration information includes an index of a control resource set pool associated with each control resource set, wherein, based on the configuration information, an index of a control resource set pool associated with a first control resource set and an index of a control resource set pool associated with a second control resource set are determined as different values; receiving (S1420) first downlink control information, DCI, based on the first control resource set and second DCI based on the second control resource set via physical downlink control channels, PDCCHs; determining (S1430) a physical uplink control channel, PUCCH, resource for a transmission of the HARQ-ACK information; and transmitting (S1440) the HARQ-ACK information based on the determined PUCCH resource, characterized in that a feedback mode of the HARQ-ACK information is configured as a joint mode, wherein an order of the first DCI and the second DCI is determined based on (i) an index of a monitoring occasion related to the PDCCHs, (ii) a cell index, and (iii) an index of each control resource set pool, wherein the PUCCH resource is determined based on a PUCCH resource indicator field of a last DCI among the first DCI and the second DCI which are indexed based on the determined order, after a PUCCH resource set related to the PUCCH resource is determined, wherein the PUCCH resource set related to the PUCCH resource is determined based on a payload size, and wherein the payload size includes a payload size of the HARQ-ACK information in which a first HARQ-ACK codebook associated with the first control resource set and a second HARQ-ACK codebook associated with the second control resource set are concatenated. receiving (S1410) configuration information related to a plurality of control resource sets, wherein the configuration information includes an index of a control resource set pool associated with each control resource set, wherein, based on the configuration information, an index of a control resource set pool associated with a first control resource set and an index of a control resource set pool associated with a second control resource set are determined as different values; receiving (S1420) first downlink control information, DCI, based on the first control resource set and second DCI based on the second control resource set via physical downlink control channels, PDCCHs; determining (S1430) a physical uplink control channel, PUCCH, resource for a transmission of the HARQ-ACK information; and transmitting (S1440) the HARQ-ACK information based on the determined PUCCH resource, characterized in that a feedback mode of the HARQ-ACK information is configured as a joint mode, wherein an order of the first DCI and the second DCI is determined based on (i) an index of a monitoring occasion related to the PDCCHs, (ii) a cell index, and (iii) an index of each control resource set pool, wherein the PUCCH resource is determined based on a PUCCH resource indicator field of a last DCI among the first DCI and the second DCI which are indexed based on the determined order, after a PUCCH resource set related to the PUCCH resource is determined, wherein the PUCCH resource set related to the PUCCH resource is determined based on a payload size, and wherein the payload size includes a payload size of the HARQ-ACK information in which a first HARQ-ACK codebook associated with the first control resource set and a second HARQ-ACK codebook associated with the second control resource set are concatenated. <EOS>
