A first DCI format can configure the parameters for a channel transmission and a second DCI format can trigger the channel transmission and indicate respective one or more transmission time intervals. ## Claims ### Claim 1 A method for a user equipment (UE) to provide hybrid automatic repeat request acknowledgment (HARQ-ACK) information, the method comprising: receiving: information for a number of groups wherein, for each group from the number of groups, the information includes a set of cells and a set of hybrid automatic repeat request (HARQ) processes for each cell from the set of cells, and a physical downlink control channel (PDCCH) that provides a downlink control information (DCI) format; determining: a request to provide HARQ-ACK information based on a first field of the DCI format, and an indication for a group from the number of groups based on a second field of the DCI format; and transmitting a first channel that includes first HARQ-ACK information corresponding to the set of HARQ processes for each cell from the set of cells of the group. ### Claim 2 (depends on 1) The method of claim 1, wherein the first field includes one bit. ### Claim 3 (depends on 1) The method of claim 1, wherein a number of bits for the second field is determined based on the number of groups. ### Claim 4 (depends on 1) The method of claim 1, wherein the DCI format schedules reception or transmission of a channel. ### Claim 5 (depends on 1) The method of claim 1, wherein: the first HARQ-ACK information includes second HARQ-ACK information, and the second HARQ-ACK information is included in a second channel scheduled for transmission prior to transmission of the first channel. ### Claim 6 (depends on 5) The method of claim 5, wherein the second channel is transmitted. ### Claim 7 (depends on 5) The method of claim 5, wherein the second channel is not transmitted. ### Claim 8 A user equipment (UE), comprising: a transceiver configured to receive: information for a number of groups wherein, for each group from the number of groups, the information includes a set of cells and a set of hybrid automatic repeat request (HARQ) processes for each cell from the set of cells, and a physical downlink control channel (PDCCH) that provides a downlink control information (DCI) format; and a processor, operably connected to the transceiver, the processor configured to determine: a request to provide hybrid automatic repeat request acknowledgment (HARQ-ACK) information based on a first field of the DCI format, and an indication for a group from the number of groups based on a second field of the DCI format, wherein the transceiver is further configured to transmit a first channel that includes first HARQ-ACK information corresponding to the set of HARQ processes for each cell from the set of cells of the group. ### Claim 9 (depends on 8) The UE of claim 8, wherein the first field includes one bit. ### Claim 10 (depends on 8) The UE of claim 8, wherein a number of bits for the second field is determined based on the number of groups. ### Claim 11 (depends on 8) The UE of claim 8, wherein the DCI format schedules reception or transmission of a channel. ### Claim 12 (depends on 8) The UE of claim 8, wherein: the first HARQ-ACK information includes second HARQ-ACK information, and the second HARQ-ACK information is included in a second channel scheduled for transmission prior to transmission of the first channel. ### Claim 13 (depends on 12) The UE of claim 12, wherein the transceiver is further configured to transmit the second channel. ### Claim 14 (depends on 12) The UE of claim 12, wherein the transceiver is further configured to drop transmission of the second channel. ### Claim 15 A base station, comprising: a transceiver configured to transmit: information for a number of groups wherein, for each group from the number of groups, the information includes a set of cells and a set of hybrid automatic repeat request (HARQ) processes for each cell from the set of cells, and a physical downlink control channel (PDCCH) that provides a downlink control information (DCI) format; and a processor, operably connected to the transceiver, the processor configured to determine: a request for hybrid automatic repeat request acknowledgment (HARQ-ACK) information based on a first field of the DCI format, and an indication for a group from the number of groups based on a second field of the DCI format, wherein the transceiver is further configured to receive a first channel that includes first HARQ-ACK information corresponding to the set of HARQ processes for each cell from the set of cells of the group. ### Claim 16 (depends on 15) The base station of claim 15, wherein the first field includes one bit. ### Claim 17 (depends on 15) The base station of claim 15, wherein a number of bits for the second field is determined based on the number of groups. ### Claim 18 (depends on 15) The base station of claim 15, wherein the DCI format schedules reception or transmission of a channel. ### Claim 19 (depends on 15) The base station of claim 15, wherein: the first HARQ-ACK information includes second HARQ-ACK information, and the second HARQ-ACK information is included in a second channel scheduled for reception prior to reception of the first channel. ### Claim 20 (depends on 19) The base station of claim 19, wherein the transceiver is further configured to receive the second channel.
