Timelines and conditions for transmission of acknowledgment information

A user equipment (UE) comprising:

• a transceiver configured to receive:
• a first physical downlink control channel (PDCCH) that schedules a transmission of a physical uplink shared channel (PUSCH) transmission in a slot, and
• PDCCHs that schedule receptions of first multicast physical downlink shared channels (PDSCHs), respectively, wherein:
• a first number of the PDCCHs is not received after the first PDCCH, and
• a second number of the PDCCHs is received after the first PDCCH;
• a processor operably coupled to the transceiver, the processor configured to determine that a transmission of a physical uplink control channel (PUCCH) to provide hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with receptions of multicast PDSCHs, that include the first multicast PDSCHs, would overlap in time with the PUSCH transmission in the slot,
• wherein the transceiver is further configured to transmit the PUSCH and wherein:
• the PUSCH includes first HARQ-ACK information associated with the first number of PDCCHs, and
• the PUSCH does not include second HARQ-ACK information associated with the second number of PDCCHs.

A base station comprising:

• a transceiver configured to transmit:
• a first physical downlink control channel (PDCCH) that schedules a reception of a physical uplink shared channel (PUSCH) in a slot, and
• PDCCHs that schedule transmissions of multicast physical downlink shared channels (PDSCHs), respectively, wherein:
• a first number of the PDCCHs is not transmitted after the first PDCCH, and
• a second number of the PDCCHs is transmitted after the first PDCCH;
• a processor operably coupled to the transceiver, the processor configured to determine that a reception of a physical uplink control channel (PUCCH) to provide hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with transmissions of multicast PDSCHs, that include the first multicast PDSCHs, would overlap in time with the PUSCH reception in the slot,
• wherein the transceiver is further configured to receive the PUSCH and wherein:
• the PUSCH includes first HARQ-ACK information associated with the first number of PDCCHs, and
• the PUSCH does not include second HARQ-ACK information associated with the second number of PDCCHs.
