DCI timing for triggered scheduling in a wireless device

1. A method comprising:

receiving, by a wireless device, during a first transmission time interval (TTI), a first downlink control information (DCI) of a first triggered scheduling via first radio resources;

receiving, during a second TTI, a second DCI of a second triggered scheduling via second radio resources;

receiving, during a third TTI, a third DCI indicating a trigger;

selecting the first DCI or the second DCI based on a first start time of the first TTI and a second start time of the second TTI; and

transmitting, in response to the trigger, a transport block based on the selected DCI.

2. The method of claim 1 , wherein:

the first radio resources and the second radio resources are for a cell; and

the cell operates according to a frame structure type 3.

3. The method of claim 1 , wherein the first DCI comprises a field indicating that the first DCI is for the first triggered scheduling.

4. The method of claim 1 , wherein the second DCI comprises a field indicating that the second DCI is for the second triggered scheduling.

5. The method of claim 1 , wherein the selecting selects the first DCI based on the timing of the first TTI being earlier than the timing of the second TTI.

6. The method of claim 1 , wherein the first DCI comprises a first timing offset field indicating a first transmission timing offset.

7. The method of claim 1 , wherein the second DCI comprises a second timing offset field indicating a second transmission timing offset.

8. The method of claim 1 , wherein the third DCI is received in a common search space of the wireless device.

9. The method of claim 8 , further comprising monitoring the common control search space.

10. The method of claim 1 , wherein a transmission timing of the transport block is based on the third DCI.

11. A wireless device comprising:

one or more processors;

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

receive, during a first transmission time interval (TTI), a first downlink control information (DCI) of a first triggered scheduling via first radio resources;

receive, during a second TTI, a second DCI of a second triggered scheduling via second radio resources;

receive, during a third TTI, a third DCI indicating a trigger;

select the first DCI or the second DCI based on a first start time of the first TTI and a second start time of the second TTI; and

transmit, in response to the trigger, a transport block based on the selected DCI.

12. The wireless device of claim 11 , wherein:

the first radio resources and the second radio resources are for a cell; and

the cell operates according to a frame structure type 3.

13. The wireless device of claim 11 , wherein the first DCI comprises a field indicating that the first DCI is for the first triggered scheduling.

14. The wireless device of claim 11 , wherein the second DCI comprises a field indicating that the second DCI is for the second triggered scheduling.

15. The wireless device of claim 11 , wherein the first DCI is selected based on the timing of the first TTI being earlier than the timing of the second TTI.

16. The wireless device of claim 11 , wherein the first DCI comprises a first timing offset field indicating a first transmission timing offset.

17. The wireless device of claim 11 , wherein the second DCI comprises a second timing offset field indicating a second transmission timing offset.

18. The wireless device of claim 11 , wherein the third DCI is received in a common search space of the wireless device.

19. The wireless device of claim 18 , wherein the instructions, when executed, further cause the wireless device to monitor a common control search space.

20. The wireless device of claim 11 , wherein a transmission timing of the transport block is based on the third DCI.
