Claim 0:
1. A user equipment for use in a 3rd generation partnership project (3GPP)-based wireless communication system, the user equipment comprising:
a communication module; and
a processor configured to control the communication module,
wherein the processor is configured to:
receive a plurality of physical downlink control channels (PDCCHs), wherein each of the plurality of PDCCHs is associated with a respective reception time and a respective cell index; and
transmit a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook on a physical uplink control channel (PUCCH) resource associated with a last PDCCH among the plurality of the PDCCHs,
wherein the plurality of the PDCCHs is ordered based on a reception time and a cell index associated with each of the plurality of the PDCCHs, and
wherein, among the plurality of PDCCHs, at least two PDCCHs associated with a same reception time and a same cell index are ordered further based on a control resource set (CORESET) index associated with each of the at least two PDCCHs.
