1. A method comprising:

receiving, by a wireless device, one or more first radio resource control (RRC) messages comprising configuration parameters of a cell, wherein the configuration parameters indicate:

a minimum scheduling time-domain offset value of a bandwidth part (BWP) of the cell; and

receiving, by the wireless device, a first DCI comprising:

a BWP index indicating the BWP; and

a field indicating whether to apply the minimum scheduling time-domain offset value; and

receiving a second DCI indicating a scheduling time-domain offset value between the second DCI and a downlink data channel scheduled by the second DCI, wherein the scheduling time-domain offset value is greater than or equal to the minimum scheduling time-domain offset value based on the field indicating to apply the minimum scheduling time-domain offset value.

10. 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 first radio resource control (RRC) messages comprising configuration parameters of a cell, wherein the configuration parameters indicate:

a minimum scheduling time-domain offset value of a bandwidth part (BWP) of the cell; and

the minimum scheduling time-domain offset value is a minimum value of one or more scheduling time-domain offset values between downlink control information (DCI) and a corresponding downlink data channel schedulable by the DCI;

receive a first DCI comprising:

a BWP index indicating the BWP; and

a field indicating whether to apply the minimum scheduling time-domain offset value; and

receive a second DCI indicating a scheduling time-domain offset value between the second DCI and a downlink data channel scheduled by the second DCI, wherein the scheduling time-domain offset value is greater than or equal to the minimum scheduling time-domain offset value based on the field indicating to apply the minimum scheduling time-domain offset value.

11. The wireless device of claim 10 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive one or more second RRC messages comprising configuration parameters of a list of time-domain resource allocations.

12. The wireless device of claim 11 , wherein a time-domain resource allocation, in the list of time-domain resource allocations, comprises a time-domain offset value between a DCI and a corresponding downlink data scheduled by the DCI.

13. The wireless device of claim 11 , wherein the wireless device assumes that one or more time-domain resource allocations from the list of time-domain resource allocations are not indicated by the second DCI, wherein a time-domain offset value of each of the one or more time-domain resource allocations is smaller than the minimum scheduling time-domain offset value.

14. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive a third DCI comprising the BWP index indicating the BWP and a field indicating not to apply the minimum scheduling time-domain offset value.

15. The wireless device of claim 14 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive a fourth DCI indicating a second scheduling time-domain offset, wherein the second scheduling time-domain offset value is greater than or equal to zero based on the field in the third DCI indicating not to apply the minimum scheduling time-domain offset value.

16. The wireless device of claim 11 , wherein the one or more first RRC messages comprise a parameter of the minimum scheduling time-domain offset value of the BWP of the cell.
