1. A user equipment (UE) for use in a wireless communication system, the UE comprising:
a communication module; and
a processor configured to control the communication module,
wherein the processor is configured to:
receive one or more physical downlink control channels (PDCCHs), wherein each of the one or more PDCCHs includes:
a sub-slot-level offset for physical downlink shared channel-to-hybrid automatic repeat and request (PDSCH-to-HARQ) feedback, and
an indicator related to HARQ-acknowledgement (HARQ-ACK) multiplexing, the indicator having one of 0 or 1;
generate a first HARQ-ACK codebook associated with a first value of the indicator, based on a semi-static HARQ-ACK codebook scheme; and
transmit the first HARQ-ACK codebook via a first physical uplink control channel (PUCCH) in a sub-slot n,
wherein the semi-static HARQ-ACK codebook scheme includes:
step A: for a set R including PDSCH candidates receivable in a slot, if an end time of an element of the set R is not within sub-slots associated with the sub-slot n, the set R is updated by removing the element, and
step B: in a slot level, a same HARQ-ACK bit position is assigned to both (i) a first element with a smallest last symbol index and (ii) zero or more second elements overlapped in time with the first element, and then the first element and the zero or more second elements are removed from the updated set R.
