Abstract
For scheduling transmissions of data channels, control channels, or random access channels using downlink control information (DCI) formats, a DCI format can configure a transmission of one or multiple data channels over respective one or multiple transmission time intervals. 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.
Claims20
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.
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.
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.
