1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station (BS), i) one or more first downlink control information (DCI) formats based on one or more first COntrol REsource SETs (CORESETs) related to a first CORESET pool and ii) one or more second DCI formats based on one or more second CORESETs related to a second CORESET pool;
receiving, from the BS, i) one or more first physical downlink shared channels (PDSCHs) scheduled based on the one or more first DCI formats and ii) one or more second PDSCHs scheduled based on the one or more second DCI formats;
determining a physical uplink control channel (PUCCH) resource for transmission of hybrid automatic repeat and reQuest-acknowledgement (HARQ-ACK) information which is related to at least one of the one or more first PDSCHs and the one or more second PDSCHs; and
transmitting, to the BS, the HARQ-ACK information based on the determined PUCCH resource,
wherein each of the one or more first DCI formats and the one or more second DCI formats includes a PUCCH resource indicator field,
wherein, based on a feedback mode of the HARQ-ACK information being configured as a separate mode:
the one or more first DCI formats are indexed based on (i) a serving cell index and (ii) an index of a physical downlink control channel (PDCCH) monitoring occasion, and the one or more second DCI formats are indexed based on (i) the serving cell index and (ii) the index of the PDCCH monitoring occasion,
the first HARQ-ACK information associated with the first CORESET pool is transmitted based on a first PUCCH resource which is determined based on a first DCI format with a last index among the first DCI formats, and
the second HARQ-ACK information associated with the second CORESET pool is transmitted based on a second PUCCH resource which is determined based on a second DCI format with a last index among the second DCI formats,
wherein, based on the feedback mode of the HARQ-ACK information being configured as a joint mode:
the one or more first DCI formats and the one or more second DCI formats are indexed based on (i) the cell index, (ii) the index of the PDCCH monitoring occasion, and (iii) an index of each CORESET pool,
a third PUCCH resource is determined based on a last DCI format which is a DCI format with a last index among the one or more first DCI formats and the one or more second DCI formats, and
information in which the first HARQ-ACK information and the second HARQ-ACK information are concatenated, is transmitted based on the third PUCCH resource.
