Transmission structures and formats for DL control channels

A user equipment (UE) comprising:

• a transceiver configured to receive a physical downlink control channel (PDCCH) that provides a downlink control information (DCI) format, wherein the DCI format:
• schedules a reception of a physical downlink shared channel (PDSCH) that provides a transport block, and
• includes a channel state information (CSI) report request field with a value that triggers a CSI report;
• a processor operably coupled to the transceiver, the processor configured to determine:
• a first slot for transmission of a first physical uplink control channel (PUCCH) with hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with the transport block, and
• a second slot for transmission of a second PUCCH with the CSI report;
• wherein the transceiver is further configured to transmit:
• the first PUCCH in the first slot, and
• the second PUCCH in the second slot.

A base station comprising:

• a transceiver configured to transmit a physical downlink control channel (PDCCH) that provides a downlink control information (DCI) format, wherein the DCI format:
• schedules a reception of a physical downlink shared channel (PDSCH) that provides a transport block, and
• includes a channel state information (CSI) report request field with a value that triggers a CSI report;
• a processor operably coupled to the transceiver, the processor configured to determine:
• a first slot for reception of a first physical uplink control channel (PUCCH) with hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with the transport block, and
• a second slot for reception of a second PUCCH with the CSI report;
• wherein the transceiver is further configured to receive:
• the first PUCCH in the first slot, and
• the second PUCCH in the second slot.
