1. A user equipment (UE) for use in a wireless communication system, the UE comprising:
a processor; and
a communication module,
wherein the processor is configured to:
receive downlink control information (DCI) for downlink scheduling, wherein the DCI includes a sub-slot offset k, and k is an element of a set K: {k0, k1, . . . , km−1} (m>0);
for each element ki (ki>0) of the set K, perform one of:
if a first downlink (DL) slot corresponding to UL sub-slot #(nu−ki) is different from a second DL slot corresponding to UL sub-slot #(nu−ki−1), including hybrid automatic repeat request acknowledgement (HARQ-ACK) information for the first DL slot in a semi-static HARQ-ACK codebook, and
if the first DL slot is same as the second DL slot, skipping to include the HARQ-ACK information for the first DL slot in the semi-static HARQ-ACK codebook; and
transmit the semi-static HARQ-ACK codebook in UL sub-slot #nu,
wherein a generation of the HARQ-ACK information includes:
determining a set of valid physical downlink shared channel (PDSCH) candidates for the first DL slot, based on whether an end of a corresponding PDSCH candidate in the first DL slot is within any UL sub-slot #(nu-ko), where ko is at least part of the set K.
