Abstract

Claims (60)

1. A network node configured to communicate with a wireless device, the network node comprising processing circuitry configured to:

transmit a downlink control information (DCI) to the wireless device, the DCI configured to schedule a plurality of transport blocks (TBs), the DCI including at least one parameter that is configured to be applied to the plurality of TBs, the at least one parameter including:

a number of subframe repetitions corresponding to each TB scheduled for transmission on a physical downlink channel; and

perform communications based on the DCI.

2. The network node of claim 1 , wherein each of the plurality of TBs map to a respective hybrid automatic repeat request (HARQ) process.

3. The network node of claim 1 , wherein the processing circuitry is further configured to determine whether to enable DCI that is configured to schedule the plurality of TBs based on an amount of data in a buffer of the network node.

4. The network node of claim 1 , wherein the at least one parameter is configured to be applied to a hybrid automatic repeat request (HARQ) processes associated with retransmissions.

5. The network node of claim 1 , wherein the at least one parameter further includes at least one of:

precoding information;

downlink assignment index; and

physical uplink control channel (PUCCH) power control.

6. The network node of claim 1 , wherein the at least one parameter further includes:

demodulation reference signal (DM-RS) scrambling.

7. A wireless device configured to communicate with a network node, the wireless device comprising processing circuitry configured to:

receive a downlink control information (DCI) that is configured to schedule a plurality of transport blocks (TBs), the DCI including at least one parameter that is configured to be applied to the plurality of TBs, the at least one parameter including:

a number of subframe repetitions corresponding to each TB scheduled for transmission on a physical downlink channel; and

perform communications based on the DCI.

8. The wireless device of claim 7 , wherein each of the plurality of TBs map to a respective hybrid automatic repeat request (HARQ) process.

9. The wireless device of claim 7 , wherein the at least one parameter is configured to be applied to a hybrid automatic repeat request (HARQ) processes associated with retransmissions.

10. The wireless device of claim 7 , wherein the processing circuitry is configured to receive radio resource control (RRC) signaling that configures the wireless device to receive the DCI in a predefined format; and

the DCI in the predefined format being specific to the wireless device.

11. The wireless device of claim 7 , wherein the at least one parameter further includes at least one of:

precoding information;

downlink assignment index; and

physical uplink control channel (PUCCH) power control.

12. The wireless device of claim 7 , wherein the at least one parameter further includes:

demodulation reference signal (DM-RS) scrambling.

13. A method for a network node configured to communicate with a wireless device, the method comprising:

a number of subframe repetitions corresponding to each TB scheduled for transmission on a physical downlink channel; and

performing communications based on the DCI.

14. The method of claim 13 , wherein each of the plurality of TBs map to a respective hybrid automatic repeat request (HARQ) process.

15. The method of claim 13 , further comprising determining whether to enable DCI that is configured to schedule the plurality of TBs based on an amount of data in a buffer of the network node.

16. The method of claim 13 , wherein the at least one parameter is configured to be applied to a hybrid automatic repeat request (HARQ) processes associated with retransmissions.

17. The method of claim 13 , wherein the plurality of TBs correspond to at least one uplink TB and at least one downlink TB.

18. The method of claim 13 , further comprising causing transmission of radio resource control (RRC) signaling to configure the wireless device to receive the DCI in a predefined format; and

the DCI in the predefined format being specific to the wireless device.

19. The method of claim 13 , wherein the at least one parameter further includes at least one of:

precoding information;

downlink assignment index; and
