Radio link failure report for connection failure during random access
A wireless device may receive, from a base station, radio resource control (RRC) configuration parameters of a cell comprising a bandwidth part (BWP). A wireless device may transmit a radio link failure report indicating a connection failure during a random access procedure of the wireless device. The radio link failure report may comprises a cell identifier of the cell and a subcarrier spacing parameter indicating a subcarrier spacing of the BWP associated with the connection failure.
1. 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 a radio link failure report indicating a connection failure during a random access procedure of the wireless device, wherein the radio link failure report comprises:
a cell identifier of the cell; and
a subcarrier spacing parameter indicating a subcarrier spacing of the BWP associated with the connection failure.
2. The wireless device of claim 1 , wherein the radio link failure report further comprises a radio link failure cause parameter indicating a cause of the connection failure is a random access problem.
3. The wireless device of claim 1 , wherein the radio link failure report further comprises a parameter indicating a bandwidth of the BWP associated with the connection failure.
4. The wireless device of claim 1 , wherein the radio link failure report is transmitted to the base station.
5. The wireless device of claim 1 , wherein:
the base station is a first base station; and
the radio link failure report is transmitted to a second base station.
6. The wireless device of claim 1 , wherein the radio link failure report further comprises a measurement result of a last serving cell.
7. The wireless device of claim 1 , wherein the radio link failure report further comprises at least one of:
a time value indicating an elapsed time since the connection failure; or
a cell radio network temporary identifier (C-RNTI) of the wireless device for the cell.
8. 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 a base station, radio resource control (RRC) configuration parameters of a cell comprising a bandwidth part (BWP); and
transmit a radio link failure report indicating a connection failure during a random access procedure of the wireless device, wherein the radio link failure report comprises:
a cell identifier of the cell; and
a parameter indicating a bandwidth of the BWP associated with the connection failure.
9. The wireless device of claim 8 , wherein the radio link failure report further comprises a radio link failure cause parameter indicating a cause of the connection failure is a random access problem.
10. The wireless device of claim 8 , wherein the radio link failure report further comprises a subcarrier spacing parameter indicating a subcarrier spacing of the BWP associated with the connection failure.
11. The wireless device of claim 8 , wherein the radio link failure report is transmitted to the base station.
12. The wireless device of claim 8 , wherein:
the base station is a first base station; and
the radio link failure report is transmitted to a second base station.
13. The wireless device of claim 8 , wherein the radio link failure report further comprises a measurement result of a last serving cell.
14. The wireless device of claim 8 , wherein the radio link failure report further comprises at least one of:
a time value indicating an elapsed time since the connection failure; or
a cell radio network temporary identifier (C-RNTI) of the wireless device for the cell.
15. A method comprising:
receiving, by a wireless device from a base station, radio resource control (RRC) configuration parameters of a cell comprising a bandwidth part (BWP); and
transmitting a radio link failure report indicating a connection failure during a random access procedure of the wireless device, wherein the radio link failure report comprises:
a cell identifier of the cell; and
a subcarrier spacing parameter indicating a subcarrier spacing of the BWP associated with the connection failure.
16. The method of claim 15 , wherein the radio link failure report further comprises a radio link failure cause parameter indicating a cause of the connection failure is a random access problem.
17. The method of claim 15 , wherein the radio link failure report further comprises a parameter indicating a bandwidth of the BWP associated with the connection failure.
18. The method of claim 15 , wherein the radio link failure report is transmitted to the base station.
19. The method of claim 15 , wherein:
