Timer parameter handling with sidelink downlink control information

1. A method comprising:

receiving, by a wireless device and before a scheduled sidelink transmission via a resource of one or more resources of a sidelink resource pool of a cell, a downlink control information (DCI) indicating switching from a first bandwidth part of the cell to a second bandwidth part of the cell as an active bandwidth part; and

in response to the DCI:

activating the second bandwidth part after a delay from the receiving the DCI;

dropping the scheduled sidelink transmission via the resource of the one or more resources; and

skipping monitoring physical sidelink control channels for sidelink control information during the delay.

2. The method of claim 1 , wherein the scheduled sidelink transmission:

overlaps with a time duration of the delay; or

is after the delay from reception of the DCI.

3. The method of claim 1 , wherein the physical sidelink control channels are transmitted by one or more second wireless devices.

4. The method of claim 1 , further comprising determining to exclude a set of resources based on one or more sidelink slots during the delay.

5. The method of claim 4 , wherein the set of resources comprise:

a sidelink slot based on a periodicity of one or more periodicities configured for the sidelink resource pool; and

a first sidelink slot of the one or more sidelink slots.

6. The method of claim 4 , further comprising excluding the set of resources from being selected for a sidelink transmission.

7. The method of claim 1 , wherein the sidelink resource pool overlaps with frequency resources of the cell.

8. The method of claim 1 , wherein the cell is time domain division (TDD) multiplexed, and wherein frequency resources of an uplink carrier of the cell overlap with frequency resource of a downlink carrier of the cell.

9. The method of claim 1 , further comprising determining, based on a bandwidth part inactivity timer of the cell, to switch to a third bandwidth part of the cell as an active bandwidth part.

10. The method of claim 9 , in response to the determining to switch to the third bandwidth part of the cell:

activating the third bandwidth part after a second delay from the determining; and

skipping monitoring physical sidelink control channels for sidelink control information during the second delay.

11. 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, before a scheduled sidelink transmission via a resource of one or more resources of a sidelink resource pool of a cell, a downlink control information (DCI) indicating switching from a first bandwidth part of the cell to a second bandwidth part of the cell as an active bandwidth part; and

in response to the DCI:

activate the second bandwidth part after a delay from the reception of the DCI;

drop the scheduled sidelink transmission via the resource of the one or more resources; and

skip monitoring physical sidelink control channels for sidelink control information during the delay.

12. The wireless device of claim 11 , wherein the scheduled sidelink transmission:

overlaps with a time duration of the delay; or

is after the delay from reception of the DCI.

13. The wireless device of claim 11 , wherein the physical sidelink control channels are transmitted by one or more second wireless devices.

14. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to determine to exclude a set of resources based on one or more sidelink slots during the delay.

15. The wireless device of claim 14 , wherein the set of resources comprise:

a sidelink slot based on a periodicity of one or more periodicities configured for the sidelink resource pool; and

a first sidelink slot of the one or more sidelink slots.

16. The wireless device of claim 14 , wherein the the instructions, when executed by the one or more processors, further cause the wireless device to exclude the set of resources from being selected for a sidelink transmission.

17. The wireless device of claim 11 , wherein the sidelink resource pool overlaps with frequency resources of the cell.

18. The wireless device of claim 11 , wherein the cell is time domain division (TDD) multiplexed, and wherein frequency resources of an uplink carrier of the cell overlap with frequency resource of a downlink carrier of the cell.

19. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to determine, based on a bandwidth part inactivity timer of the cell, to switch to a third bandwidth part of the cell as an active bandwidth part.

20. 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, before a scheduled sidelink transmission via a resource of one or more resources of a sidelink resource pool of a cell, a downlink control information (DCI) indicating switching from a first bandwidth part of the cell to a second bandwidth part of the cell as an active bandwidth part; 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 DCI; and

in response to the DCI:

activate the second bandwidth part after a delay from the reception of the DCI;

drop the scheduled sidelink transmission via the resource of the one or more resources; and

skip monitoring physical sidelink control channels for sidelink control information during the delay.
