Abstract

Claims (83)

1. A method comprising:

receiving, by a wireless device from a first base station, a radio resource control (RRC) release message comprising a suspend configuration, wherein:

the suspend configuration comprises a configuration of a small data transmission (SDT) procedure; and

the configuration indicates a radio bearer configured for the SDT procedure;

suspending, based on the suspend configuration, one or more radio bearers comprising the radio bearer configured for the SDT procedure;

based on initiating the SDT procedure:

resuming the radio bearer configured for the SDT procedure; and

transmitting, to a second base station, a radio resource control (RRC) resume request message;

communicating, with the second base station and during the SDT procedure, data associated with the SDT procedure;

transmitting, by the wireless device to the second base station and during the SDT procedure, a user equipment (UE) assistance information message comprising:

a non-SDT indication, wherein the non-SDT indication indicates availability of data mapped to a radio bearer which is not configured for the SDT procedure; and

a resume cause associated with the data; and

receiving, from the second base station and after transmitting the UE assistance information message, an RRC response message.

2. The method of claim 1 , wherein the RRC response message comprises at least one of:

an RRC resume message;

an RRC release message; or

an RRC setup message.

3. The method of claim 1 , wherein the suspend configuration comprises at least one of:

a resume identity;

a radio access network (RAN) paging cycle;

a RAN based notification area (RNA) configuration; or

network hop chaining count (NCC) value.

4. The method of claim 3 , wherein the RNA configuration comprises at least one of:

RNA notification area information; or

periodic RNA update timer value.

5. The method of claim 1 , wherein the first base station receives, from the second base station, a partial context of the wireless device.

6. The method of claim 5 , wherein the partial context is a context associated with a lower layer of the wireless device, a radio link control layer of the wireless device, a medium access control layer of the wireless device, and/or a physical layer of the wireless device.

7. The method of claim 1 , wherein the second base station comprises a last serving base station or an anchor base station.

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 first base station, a radio resource control (RRC) release message comprising a suspend configuration, wherein:

the suspend configuration comprises a configuration of a small data transmission (SDT) procedure; and

the configuration indicates a radio bearer configured for the SDT procedure;

suspend, based on the suspend configuration, one or more radio bearers comprising the radio bearer configured for the SDT procedure;

based on initiating the SDT procedure:

resume the radio bearer configured for the SDT procedure; and

transmit, to a second base station, a radio resource control (RRC) resume request message;

communicate, with the second base station and during the SDT procedure, data associated with the SDT procedure;

transmit, by the wireless device to the second base station and during the SDT procedure, a user equipment (UE) assistance information message comprising:

a non-SDT indication, wherein the non-SDT indication indicates availability of data mapped to a radio bearer which is not configured for the SDT procedure; and

a resume cause associated with the data; and

receive, from the second base station and after transmitting the UE assistance information message, an RRC response message.

9. The wireless device of claim 8 , wherein the RRC response message comprises at least one of:

an RRC resume message;

an RRC release message; or

an RRC setup message.

10. The wireless device of claim 8 , wherein the suspend configuration comprises at least one of:

a resume identity;

a radio access network (RAN) paging cycle;

a RAN based notification area (RNA) configuration; or

network hop chaining count (NCC) value.

11. The wireless device of claim 10 , wherein the RNA configuration comprises at least one of:

RNA notification area information; or

periodic RNA update timer value.

12. The wireless device of claim 8 , wherein the first base station receives, from the second base station, a partial context of the wireless device.

13. The wireless device of claim 12 , wherein the partial context is a context associated with a lower layer of the wireless device, a radio link control layer of the wireless device, a medium access control layer of the wireless device, and/or a physical layer of the wireless device.

14. The wireless device of claim 8 , wherein the second base station comprises a last serving base station or an anchor base station.

15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:

receive, from a first base station, a radio resource control (RRC) release message comprising a suspend configuration, wherein:

the suspend configuration comprises a configuration of a small data transmission (SDT) procedure; and

the configuration indicates a radio bearer configured for the SDT procedure;

suspend, based on the suspend configuration, one or more radio bearers comprising the radio bearer configured for the SDT procedure;

based on initiating the SDT procedure:

resume the radio bearer configured for the SDT procedure; and

transmit, to a second base station, a radio resource control (RRC) resume request message;

communicate, with the second base station and during the SDT procedure, data associated with the SDT procedure;

transmit, by the wireless device to the second base station and during the SDT procedure, a user equipment (UE) assistance information message comprising:

a non-SDT indication, wherein the non-SDT indication indicates availability of data mapped to a radio bearer which is not configured for the SDT procedure; and

a resume cause associated with the data; and

receive, from the second base station and after transmitting the UE assistance information message, an RRC response message.

16. The non-transitory computer-readable medium of claim 15 , wherein the RRC response message comprises at least one of:

an RRC resume message;

an RRC release message; or

an RRC setup message.

17. The non-transitory computer-readable medium of claim 15 , wherein the suspend configuration comprises at least one of:

a resume identity;

a radio access network (RAN) paging cycle;

a RAN based notification area (RNA) configuration; or

network hop chaining count (NCC) value.

18. The non-transitory computer-readable medium of claim 17 , wherein the RNA configuration comprises at least one of:

RNA notification area information; or

periodic RNA update timer value.

19. The non-transitory computer-readable medium of claim 15 , wherein the first base station receives, from the second base station, a partial context of the wireless device.

20. The non-transitory computer-readable medium of claim 19 , wherein the partial context is a context associated with a lower layer of the wireless device, a radio link control layer of the wireless device, a medium access control layer of the wireless device, and/or a physical layer of the wireless device.
