1. A user equipment for use in a wireless communication system, the user equipment comprising:
a communication module; and
a processor that controls the communication module, wherein the processor is configured to:
receive a physical downlink control channel (PDCCH) having the following information:
index information indicating one entry in a time-domain resource allocation (TDRA) table for physical downlink shared channel (PDSCH) allocation, and
timing information indicating one value in a K1-set {K1i} (i represents an index of element) for PDSCH-to-hybrid automatic repeat and request (HARQ) slot timing;
determine a PDSCH candidate set of slot n-K1i for all K1 values in the K1-set, wherein slot n is indicated using the timing information; and
transmit a semi-static HARQ-ACK codebook in the slot n, based on the determined PDSCH candidate set of each slot,
wherein when determining the PDSCH candidate set, the K1-set is replaced by a union of ‘the K1-set {K1i;}+{dk}’ based on at least one entry in the TDRA table being associated with a plurality of PDCCH-to-PDSCH slot timing KO values, and
wherein, dk (k represents an index of element) corresponds to a slot index difference between a slot to which a last PDSCH can be allocated and a slot to which a k-th PDSCH can be allocated based on the plurality of PDCCH-to-PDSCH timing K0 values, across all entries in the TDRA table.
