Configured grant processes in a wireless device

1. A method comprising:

receiving, by a wireless device, one or more messages comprising configuration parameters indicating a plurality of configured grant configurations for bandwidth parts (BWPs) of a cell;

receiving a downlink control information indicating activation or release of a first configured grant configuration, among the plurality of configured grant configurations, for a first BWP of the BWPs;

validating the downlink control information as a configured grant activation or a configured grant activation release based on one or more values of one or more fields of the downlink control information; and

based on the validating the downlink control information:

activating or releasing the first configured grant configuration; and

transmitting a confirmation indicating that the wireless device received the downlink control information indicating the activation or the release of the first configured grant configuration, wherein the confirmation comprises:

an identifier of the first BWP; and

an identifier of a sub-band of a plurality of sub-bands of the first BWP.

2. The method of claim 1 , wherein the first configured grant configuration is for the sub-band of the first BWP.

3. The method of claim 2 , wherein the sub-band is a listen-before-talk sub-band.

4. The method of claim 1 , wherein the confirmation further comprises an identifier of the cell.

5. The method of claim 1 , wherein the confirmation further comprises an identifier of the first configured grant configuration.

6. The method of claim 1 , wherein the confirmation is a medium-access control control element (MAC CE).

7. A wireless device comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the wireless device to:

receive one or more messages comprising configuration parameters indicating a plurality of configured grant configurations for bandwidth parts (BWPs) of a cell;

receive a downlink control information indicating activation or release of a first configured grant configuration, among the plurality of configured grant configurations, for a first BWP of the BWPs;

validate the downlink control information as a configured grant activation or a configured grant activation release based on one or more values of one or more fields of the downlink control information; and

based on validating the downlink control information:

activate or release the first configured grant configuration based on a validation of the downlink control information as a configured grant activation or a configured grant activation release; and

transmit a confirmation indicating that the wireless device received the downlink control information indicating the activation or the release of the first configured grant configuration, wherein the confirmation comprises:

an identifier of the first BWP; and

an identifier of a sub-band of a plurality of sub-bands of the first BWP.

8. The wireless device of claim 7 , wherein the first configured grant configuration is for the sub-band of the first BWP.

9. The wireless device of claim 8 , wherein the sub-band is a listen-before-talk sub-band.

10. The wireless device of claim 7 , wherein the confirmation further comprises an identifier of the cell.

11. The wireless device of claim 7 , wherein the confirmation further comprises an identifier of the first configured grant configuration.

12. The wireless device of claim 7 , wherein the confirmation is a medium-access control control element (MAC CE).

13. A system comprising:

a base station comprising;

one or more first processors; and

first memory storing first instructions that, when executed by the one or more first processors, cause the base station to:

transmit one or more messages comprising configuration parameters indicating a plurality of configured grant configurations for bandwidth parts (BWPs) of a cell; and

transmit a downlink control information indicating activation or release of a first configured grant configuration, among the plurality of configured grant configurations, for a first BWP of the BWPs; and

a wireless device comprising:

one or more second processors; and

second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:

receive the one or more messages and the downlink control information;

validate the downlink control information as a configured grant activation or a configured grant activation release based on one or more values of one or more fields of the downlink control information; and

based on validating the downlink control information:

activate or release the first configured grant configuration based on a validation of the downlink control information as a configured grant activation or a configured grant activation release; and

transmit, to the base station, a confirmation indicating that the wireless device received the downlink control information indicating the activation or the release of the first configured grant configuration, wherein the confirmation comprises:

 an identifier of the first BWP; and

 an identifier of a sub-band of a plurality of sub-bands of the first BWP.

14. The system of claim 13 , wherein the first configured grant configuration is for the sub-band of the first BWP.

15. The system of claim 14 , wherein the sub-band is a listen-before-talk sub-band.

16. The system of claim 13 , wherein the confirmation further comprises an identifier of the cell.

17. The system of claim 13 , wherein the confirmation further comprises an identifier of the first configured grant configuration.

18. The system of claim 13 , wherein the confirmation is a medium-access control control element (MAC CE).
