1. A user equipment (UE) comprising:
a transceiver configured to receive:
a configuration for first control resource sets (CORESETs) and second CORESETs,
physical downlink control channels (PDCCHs) in the first or second CORESETs, wherein the PDCCHs provide respective downlink control information (DCI) formats scheduling respective receptions of physical downlink shared channels (PDSCHs), and
the PDSCHs corresponding to the PDCCHs; and
a processor operably coupled to the transceiver, the processor configured to determine hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits in response to a PDSCH reception,
wherein:
when a PDCCH reception is in a CORESET from the first CORESETs, the HARQ-ACK information bits are in a first HARQ-ACK codebook,
when the PDCCH reception is in a CORESET from the second CORESETs, the HARQ-ACK information bits are in a second HARQ-ACK codebook, and
the transceiver is further configured to transmit a first physical uplink control channel (PUCCH) with the first HARQ-ACK codebook and a second PUCCH with the second HARQ-ACK codebook.
