Abstract
A network node causes transmission of DCI that includes information for scheduling two or more TBs over two or more communication slots. The two or more TBs are associated with two or more HARQ process IDs. The information includes one or more of: a PUCCH resource indicator configured to indicate at least one resource for use for transmitting HARQ feedback related to the two or more TBs; a DAI configured to indicate a position of HARQ feedback related to the two or more TBs, in a HARQ codebook; a HARQ process ID indicator indicating two or more HARQ process IDs; and one or more NDIs configured to indicate whether at least one of the two or more TBs is a retransmission.
Claims22
A wireless device comprising processing circuitry configured to:
- receive downlink control information (DCI), the DCI including information for scheduling two or more transport blocks (TBs) over two or more communication slots, the two or more transport blocks are associated with two or more Hybrid Automatic Repeat Request (HARQ) process identifiers (IDs), the information for scheduling including one or more of:
- a PUCCH resource indicator configured to indicate at least one resource for the wireless device to use for transmitting HARQ feedback related to the two or more TBs;
- a Downlink Assignment Indicator (DAI) configured to indicate a position of HARQ feedback related to the two or more TBs, in a HARQ codebook;
- a HARQ process ID indicator indicating the two or more HARQ process IDs;
- one or more New Data Indicators (NDIs) configured to indicate whether at least one of the two or more TBs is a retransmission;
- and
- communicate using the two or more TBs based at least in part on the DCI.
A method implemented by a wireless device, the method comprising:
- receiving downlink control information (DCI), the DCI including information for scheduling two or more transport blocks (TBs) over two or more communication slots, the two or more transport blocks are associated with two or more Hybrid Automatic Repeat Request (HARQ) process identifiers (IDs), the information for scheduling includes one or more of:
- a PUCCH resource indicator configured to indicate at least one resource for the wireless device to use for transmitting HARQ feedback related to the two or more TBs;
- a Downlink Assignment Indicator (DAI) configured to indicate a position of HARQ feedback related to the two or more TBs, in a HARQ codebook;
- a HARQ process ID indicator indicating the two or more HARQ process IDs;
- one or more New Data Indicators (NDIs) configured to indicate whether at least one of the two or more TBs is a retransmission;
- and
- communicating using the two or more TBs based at least in part on the DCI.
