Triggering a buffer status report

1. A method comprising:

transmitting, by a wireless device, one or more radio resource control (RRC) messages indicating assistance information, wherein the assistant information indicates:

an identifier indicating a logical channel; and

one or more periodicities associated with the logical channel;

receiving, in response to the assistance information, one or more second RRC messages indicating one or more configured grant configurations;

triggering, by the wireless device, a buffer status report in response to data of the logical channel becoming available; and

in response to receiving one or more activation commands indicating activation of the one or more configured grant configurations, canceling the buffer status report.

2. The method of claim 1 , wherein the canceling the buffer status report is based on a condition being met.

3. The method of claim 2 , wherein the condition is met when a priority associated with the logical channel is higher than or equal to a threshold.

4. The method of claim 2 , wherein the condition is met when a scheduling request (SR) configuration associated with the logical channel is configured to skip a buffer status reporting.

5. The method of claim 1 , further comprising:

transmitting a scheduling request (SR) in response to the triggering the buffer status report; and

receiving one or more third RRC messages comprising a SR configuration associated with the logical channel and a second logical channel.

6. The method of claim 5 , further comprising triggering a second SR based on data becoming available for the second logical channel.

7. The method of claim 6 , further comprising canceling the SR in response to the receiving the one or more activation commands.

8. The method of claim 6 , further comprising keeping the second SR in response to the receiving the one or more activation commands.

9. The method of claim 1 , wherein the assistance information further comprises a buffer size level of the logical channel, wherein the buffer size level indicates a nominal buffer status level associated with the logical channel.

10. The method of claim 9 , wherein the canceling the buffer status report is in response to a buffer status level with data being equal or smaller than the buffer size level indicated by the assistance information.

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:

transmit one or more radio resource control (RRC) messages indicating assistance information, wherein the assistant information indicates:

an identifier indicating a logical channel; and

one or more periodicities associated with the logical channel;

receive, in response to the assistance information, one or more second RRC messages indicating one or more configured grant configurations;

trigger a buffer status report in response to data of the logical channel becoming available; and

in response to receiving one or more activation commands indicating activation of the one or more configured grant configurations, cancel the buffer status report.

12. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to cancel the buffer status report is based on a condition being met.

13. The wireless device of claim 12 , wherein the condition is met when a priority associated with the logical channel is higher than or equal to a threshold.

14. The wireless device of claim 12 , wherein the condition is met when a scheduling request (SR) configuration associated with the logical channel is configured to skip a buffer status reporting.

15. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to: further comprising:

transmit a scheduling request (SR) in response to the triggering the buffer status report; and

receive one or more third RRC messages comprising a SR configuration associated with the logical channel and a second logical channel.

16. The wireless device of claim 15 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to trigger a second SR based on data becoming available for the second logical channel.

17. The wireless device of claim 16 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to cancel the SR in response to the receiving the one or more activation commands.

18. The wireless device of claim 16 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to keep the second SR in response to the receiving the one or more activation commands.

19. The wireless device of claim 11 , wherein the assistance information further comprises a buffer size level of the logical channel, wherein the buffer size level indicates a nominal buffer status level associated with the logical channel.

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:

transmit one or more radio resource control (RRC) messages indicating assistance information, wherein the assistant information indicates:

an identifier indicating a logical channel; and

one or more periodicities associated with the logical channel;

receive, in response to the assistance information, one or more second RRC messages indicating one or more configured grant configurations;

trigger a buffer status report in response to data of the logical channel becoming available; and

in response to receiving one or more activation commands indicating activation of the one or more configured grant configurations, cancel the buffer status report.
