5. A user equipment (UE), comprising:
processing circuitry;
a transceiver coupled to the processing circuitry; and
a non-transitory computer-readable medium coupled to the processing circuitry and storing one or more computer-executable instructions that, when executed by the processing circuitry, cause the UE to:
receive, through the transceiver, at least one first Downlink Control Information (DCI) format for scheduling at least one Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) codebook in at least one first Physical Uplink Control CHannel (PUCCH) in at least one first slot;
receive, through the transceiver, a second DCI format for scheduling a retransmission of a first HARQ-ACK codebook of the at least one HARQ-ACK codebook in a second PUCCH, the second DCI format being received in a second slot and indicating a first slot offset;
determine one of the at least one first slot; and
transmit, through the transceiver, the first HARQ-ACK codebook scheduled in the one of the at least one first slot via the second PUCCH, wherein:
in a case that the first slot offset includes a positive value, the one of the at least one first slot is determined by counting backward, from the second slot, a number of slots indicated by the first slot offset, and
in a case that the first slot offset includes a negative value, the one of the at least one first slot is determined by counting forward, from the second slot, the number of slots indicated by the first slot offset.
