Radio link failure information for PDCP duplication

1. A method comprising:

receiving, by a wireless device from a first base station, a packet duplication activation command for duplication of one or more packet data convergence protocol (PDCP) packets associated with a first bearer;

transmitting, based on the packet duplication activation command, one or more duplicated PDCP packets associated with the first bearer;

determining a connection failure associated with a first cell of the first base station;

determining, based on the connection failure, a second cell of a second base station for a radio resource control connection to the second base station; and

transmitting, to the second base station, a radio resource control message comprising a radio link failure report comprising a first information element indicating that at least one of the one or more PDCP packets was duplicated at a time associated with the connection failure.

2. The method of claim 1 , further comprising receiving, from the first base station, an other radio resource control message comprising one or more PDCP packet duplication configuration parameters indicating that at least one of the one or more PDCP packets associated with the first bearer is duplicated.

3. The method of claim 1 , wherein the radio link failure report further comprises one or more of:

an indication that PDCP packet duplication was activated; or

an indication that PDCP packet duplication for one or more bearers was configured.

4. The method of claim 1 , wherein the connection failure comprises one or more of:

a radio link failure; or

a handover failure.

5. The method of claim 1 , wherein the determination of the connection failure is based on a number of radio link control retransmissions of one or more packets comprising the one or more duplicated PDCP packets associated with the first bearer.

6. The method of claim 1 , wherein the determination of the connection failure is based on one or more of:

a number of radio link control retransmissions;

one or more out-of-sync detections; or

one or more random access failures.

7. The method of claim 1 , wherein the first bearer is a signaling radio bearer.

8. A method comprising:

receiving, by a wireless device from a first base station, a first radio resource control message comprising one or more packet data convergence protocol (PDCP) packet duplication configuration parameters indicating that PDCP packets associated with a first bearer are duplicated;

receiving, from the first base station, a packet duplication activation command for the first bearer;

transmitting, based on the packet duplication activation command and the one or more PDCP packet duplication configuration parameters, one or more duplicated PDCP packets associated with the first bearer;

determining a connection failure associated with a first cell of the first base station;

determining, based on the connection failure, a second cell of a second base station for a radio resource control connection to the second base station; and

transmitting, to the second base station, a second radio resource control message comprising a radio link failure report comprising a first information element indicating that PDCP packets were duplicated at a time associated with the connection failure.

9. The method of claim 8 , wherein the packet duplication activation command comprises a packet duplication activation command for duplication of PDCP packets of a first bearer.

10. The method of claim 8 , wherein the radio link failure report further comprises one or more of:

an indication that PDCP packet duplication was activated; or

an indication that PDCP packet duplication for one or more bearers was configured.

11. The method of claim 8 , wherein the connection failure comprises one or more of:

a radio link failure; or

a handover failure.

12. The method of claim 8 , wherein the determination of the connection failure is based on a number of radio link control retransmissions of one or more packets comprising the one or more duplicated PDCP packets associated with the first bearer.

13. The method of claim 8 , wherein the determination of the connection failure is based on one or more of:

a number of radio link control retransmissions;

one or more out-of-sync detections; or

one or more random access failures.

14. The method of claim 8 , wherein the first bearer is a signaling radio bearer.

15. A method comprising:

transmitting, by a first base station to a wireless device, a first radio resource control message comprising one or more packet data convergence protocol (PDCP) packet duplication configuration parameters indicating that one or more PDCP packets associated with a first bearer are duplicated;

transmitting, to the wireless device, a packet duplication activation command for the first bearer;

receiving, from a second base station, a radio link failure report comprising a first information element indicating that at least one of the one or more PDCP packets were duplicated at a time associated with a connection failure associated with a first cell of the first base station; and

configuring, based on the first information element, one or more radio resource configuration parameters.

16. The method of claim 15 , wherein the radio link failure report further comprises one or more of:

an indication that PDCP packet duplication was activated; or

an indication that PDCP packet duplication for one or more bearers was configured.

17. The method of claim 15 , further comprising initiating, by the first base station, a handover of a second wireless device at least based on the one or more radio resource configuration parameters.

18. The method of claim 15 , wherein the one or more radio resource configuration parameters comprise one or more of:

a radio signal received quality threshold for a handover trigger; or

a radio signal received power threshold for a handover trigger.

19. The method of claim 15 , wherein the one or more radio resource configuration parameters comprise one or more PDCP duplication configuration parameters.

20. The method of claim 15 , further comprising determining, by the first base station, the connection failure.
