Validation of a DCI format

1. A method comprising:

receiving, by a wireless device, a downlink control information (DCI) comprising:

a hybrid automatic repeat request process number field comprising one or more first bits; and

a redundancy version field comprising one or more second bits;

validating the DCI, wherein the validating is:

based on the one or more second bits;

based on comparing the one or more first bits with a first sequence of one or more bits, determined using a first configuration parameter, in response to:

the one or more first bits not indicating a configuration index; and

the DCI having a first format; and

not based on comparing the one or more first bits with the first sequence in response to the DCI having a second format; and

activating or deactivating resources.

2. The method of claim 1 , further comprising receiving configured grant configuration parameters of an uplink configured grant configuration, wherein the resources are associated with the uplink configured grant configuration.

3. The method of claim 1 , further comprising receiving semi-persistent scheduling (SPS) configuration parameters of a downlink SPS configuration, wherein the resources are associated with the downlink SPS configuration.

4. The method of claim 1 , wherein the DCI is associated with a configured scheduling radio network temporary identifier.

5. The method of claim 4 , wherein:

the DCI further comprises a new data indicator field; and

the validating the DCI is further based on the DCI being associated with the configured scheduling radio network temporary identifier and based on a value of the new data indicator field being zero.

6. The method of claim 1 , wherein the first configuration parameter indicates a first number of bits in the first sequence of the one or more bits.

7. The method of claim 6 , wherein the first sequence of one or more bits are all zeros.

8. The method of claim 1 , wherein the validating the DCI is based on comparing the one or more second bits with a second sequence of one or more bits determined using a second configuration parameter.

9. The method of claim 8 , wherein the second configuration parameter indicates a second number of bits in the second sequence of the one or more bits.

10. The method of claim 9 , wherein the second sequence of one or more bits are all zeros.

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 a downlink control information (DCI) comprising:

a hybrid automatic repeat request process number field comprising one or more first bits; and

a redundancy version field comprising one or more second bits;

validate the DCI, wherein the validating is:

based on the one or more second bits;

based on comparing the one or more first bits with a first sequence of one or more bits, determined using a first configuration parameter, in response to:

the one or more first bits not indicating a configuration index; and

the DCI having a first format; and

not based on comparing the one or more first bits with the first sequence in response to the DCI having a second format; and

activate or deactivate resources.

12. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive configured grant configuration parameters of an uplink configured grant configuration, wherein the resources are associated with the uplink configured grant configuration.

13. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive semi-persistent scheduling (SPS) configuration parameters of a downlink SPS configuration, wherein the resources are associated with the downlink SPS configuration.

14. The wireless device of claim 11 , wherein:

the DCI further comprises a new data indicator field; and

the validating the DCI is further based on the DCI being associated with a configured scheduling radio network temporary identifier and based on a value of the new data indicator field being zero.

15. The wireless device of claim 11 , wherein the first configuration parameter indicates a first number of bits in the first sequence of the one or more bits.

16. The wireless device of claim 15 , wherein the first sequence of one or more bits are all zeros.

17. The wireless device of claim 11 , wherein the validating the DCI is based on comparing the one or more second bits with a second sequence of one or more bits determined using a second configuration parameter.

18. The wireless device of claim 17 , wherein the second configuration parameter indicates a second number of bits in the second sequence of the one or more bits.

19. The wireless device of claim 18 , wherein the second sequence of one or more bits are all zeros.

20. A system comprising:

a base station; and

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, from the base station, a downlink control information (DCI) comprising: a hybrid automatic repeat request process number field comprising one or more first bits; and a redundancy version field comprising one or more second bits; validate the DCI, wherein the validating: is based on the one or more second bits; is based on comparing the one or more first bits with a first sequence of one or more bits, determined using a first configuration parameter, in response to: the one or more first bits not indicating a configuration index; and the DCI having a first format; and is not based on comparing the one or more first bits with the first sequence in response to the DCI having a second format; and activate or deactivate resources.
