8. A user equipment (UE) comprising:
a transceiver configured to receive:
information for a set of physical uplink control channel (PUCCH) resources,
first physical downlink shared channels (PDSCHs) that provide first transport blocks (TBs), and
second PDSCHs that provide second TBs; and
a processor operably coupled to the transceiver, the processor configured to determine:
first hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits associated with the first TBs, wherein a value for each of the first HARQ-ACK information bits corresponds to positive acknowledgement (ACK),
second HARQ-ACK information bits associated with the second TBs, wherein one or more values of the second HARQ-ACK information bits correspond to a negative acknowledgement (NACK),
a first PUCCH resource from the set of PUCCH resources for transmission of a first PUCCH with the second HARQ-ACK information,
to provide the first HARQ-ACK information bits in a first slot when at least one PUCCH resource from the set of PUCCH resources overlaps in time with a transmission of a first physical uplink shared channel (PUSCH) in the first slot; and
to provide the second HARQ-ACK information bits in a second PUSCH in a second slot when the first PUCCH resource overlaps in time with a transmission of the second PUSCH in the second slot, and
to provide the second HARQ-ACK information bits in the first PUCCH in the second slot when the first PUCCH resource does not overlap in time with any PUSCH transmission in the second slot; and
wherein the transceiver is further configured to transmit:
the first PUSCH in the first slot, wherein the first PUSCH includes the first HARQ-ACK information bits when the at least one PUCCH resource overlaps in time with the first PUSCH, and
the second PUSCH in the second slot, wherein:
the second PUSCH includes the second HARQ-ACK information bits, and
the first PUCCH resource overlaps with the second PUSCH transmission, or
the first PUCCH in the second slot using the first PUCCH resource, wherein:
the first PUCCH includes the second HARQ-ACK information bits, and
the first PUCCH resource does not overlap in time with any PUSCH transmission in the second slot.
