Multiplexing unicast and multicast control information

A user equipment (UE) comprising:

• a transceiver configured to receive a downlink control information (DCI) format scheduling transmission of a physical uplink shared channel (PUSCH), wherein the DCI format includes a downlink assignment indicator (DAI) bit associated with first hybrid automatic repeat request acknowledgement (HARQ-ACK) information and with second HARQ-ACK information;
• and
• a processor operably coupled to the transceiver, the processor configured to determine to provide:
• the first HARQ-ACK information based on a value of the DAI bit, wherein the first HARQ-ACK information is associated with a first set of radio network temporary identifiers (RNTIs), and
• the second HARQ-ACK information based on the value of the DAI bit, wherein the second HARQ-ACK information is associated with a second set of RNTIs,
• wherein the transceiver is further configured to transmit the PUSCH, wherein:
• the PUSCH includes the first HARQ-ACK information and the second HARQ-ACK information, and
• the first HARQ-ACK information and the second HARQ-ACK information are associated with a Type-1 HARQ-ACK codebook, and
• wherein the processor is further configured to determine the Type-1 HARQ-ACK codebook based on:
• a union of first and second sets of slot timing values for physical uplink control channel (PUCCH) transmissions associated with the first and second HARQ-ACK information, respectively, and
• a union of first and second sets of time domain resource allocation (TDRA) values for receptions of physical downlink shared channels (PDSCHs) associated with the first and second HARQ-ACK information, respectively.

A base station comprising:

• a transceiver configured to:
• transmit a downlink control information (DCI) format scheduling reception of a physical uplink shared channel (PUSCH), wherein the DCI format includes a downlink assignment indicator (DAI) bit associated with first hybrid automatic repeat request acknowledgement (HARQ-ACK) information and with second HARQ-ACK information, and
• receive the PUSCH, wherein:
• the PUSCH includes the first HARQ-ACK information and the second HARQ-ACK information, and
• the first HARQ-ACK information and the second HARQ-ACK information are associated with a Type-1 HARQ-ACK codebook;
• and
• a processor operably coupled to the transceiver, the processor configured to determine:
• the first HARQ-ACK information based on a value of the DAI bit, wherein the first HARQ-ACK information is associated with a first set of radio network temporary identifiers (RNTIs), and
• the second HARQ-ACK information based on the value of the DAI bit, wherein the second HARQ-ACK information is associated with a second set of RNTIs,
• wherein the Type-1 HARQ-ACK codebook is based on:
• a union of first and second sets of slot timing values for physical uplink control channel (PUCCH) transmissions associated with the first and second HARQ-ACK information, respectively, and
• a union of first and second sets of time domain resource allocation (TDRA) values for receptions of physical downlink shared channels (PDSCHs) associated with the first and second HARQ-ACK information, respectively.
