Abstract

Claims (31)

1 . A method comprising:

starting, by a wireless device, a small data transmission (SDT) failure detection timer based on initiating an SDT procedure;

stopping, by the wireless device, the SDT failure detection timer based on non-SDT data arriving during the SDT procedure, wherein the stopping the SDT failure detection timer is based on transmitting a radio resource control (RRC) message for the non-SDT data arriving during the SDT procedure; and

receiving a response to the RRC message while an RRC timer is running.

2 . The method of claim 1 , wherein the transmitting the RRC message is a via an uplink dedicated control channel (UL DCCH).

3 . The method of claim 1 , further comprising starting, by the wireless device, an RRC timer based on the RRC message for the non-SDT data arriving during the SDT procedure.

4 . The method of claim 1 , further comprising starting, by the wireless device, an RRC timer based on the non-SDT data arriving during the SDT procedure.

5 . The method of claim 1 , further comprising receiving a response to the RRC message wherein the RRC message comprises an RRC resume request or an RRC early data request.

6 . The method of claim 1 , further comprising receiving a response to the RRC message while an RRC timer is running wherein the response comprises at least one of an RRC release message; an RRC early data complete message; an RRC setup message; an RRC resume message; or an RRC reject message.

7 . The method of claim 1 , further comprising transitioning, by the wireless device, to an RRC connected state based on the receiving the response to the RRC message.

8 . The method of claim 7 , further comprising transmitting, by the wireless device in the RRC connected state, the non-SDT data, based on the receiving the response to the RRC message.

9 . The method of claim 1 , further comprising transmitting, by the wireless device, the non-SDT data, based on the receiving the response to the RRC message.

10 . The method of claim 1 , further comprising stopping, by the wireless device, the RRC timer based on the receiving the response to the RRC message.

11 . An apparatus, comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the apparatus to perform:

starting, by a wireless device, a small data transmission (SDT) failure detection timer based on initiating an SDT procedure;

stopping, by the wireless device, the SDT failure detection timer based on non-SDT data arriving during the SDT procedure, wherein the stopping the SDT failure detection timer is based on transmitting a radio resource control (RRC) message for the non-SDT data arriving during the SDT procedure; and

receiving a response to the RRC message while an RRC timer is running.

12 . The apparatus of claim 11 , wherein the transmitting the RRC message is a via an uplink dedicated control channel (UL DCCH).

13 . The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus further to perform comprising starting, by the wireless device, an RRC timer based on the RRC message for the non-SDT data arriving during the SDT procedure.

14 . The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus further to perform starting, by the wireless device, an RRC timer based on the non-SDT data arriving during the SDT procedure.

15 . The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus further to perform receiving a response to the RRC message while the RRC timer is running wherein the RRC message comprises an RRC resume request.

16 . The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus further to perform transitioning, by the wireless device, to an RRC connected state based on the receiving the response to the RRC message.

17 . The apparatus of claim 16 , wherein the instructions, when executed by the one or more processors, cause the apparatus further to perform transmitting, by the wireless device in the RRC connected state, the non-SDT data, based on the receiving the response to the RRC message.

18 . The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus further to perform transmitting, by the wireless device, the non-SDT data, based on the receiving the response to the RRC message.

19 . The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, cause the apparatus further to perform stopping, by the wireless device, the RRC timer based on the receiving the response to the RRC message.

20 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to perform:

starting, by a wireless device, a small data transmission (SDT) failure detection timer based on initiating an SDT procedure;

stopping, by the wireless device, the SDT failure detection timer based on non-SDT data arriving during the SDT procedure, wherein the stopping the SDT failure detection timer is based on transmitting a radio resource control (RRC) message for the non-SDT data arriving during the SDT procedure; and

receiving a response to the RRC message while an RRC timer is running.
