Abstract

This disclosure relates to techniques for providing a framework for supporting custom signaling between a wireless device and a cellular network. A wireless device and a cellular base station may establish a wireless link. The wireless device and the cellular base station may perform custom signaling in accordance with the custom signaling framework.

Claims (66)

1. A base station, comprising:

an antenna;

a radio operably coupled to the antenna; and

a processor operably coupled to the radio;

wherein the base station is configured to:

decode signaling received from a wireless device; and

determine that the signaling received from the wireless device includes a trigger for secondary cell group (SCG) failure based on the signaling including an absolute radio frequency channel number (ARFCN) field with a value of 0, a physical cell identity (PCI) field with a value of 0, and a measurement results field being empty.

2. The base station of claim 1 , wherein the base station is further configured to:

perform a SCG failure procedure for the wireless device based on the signaling received from the wireless device.

3. The base station of claim 1 ,

wherein the SCG failure is not counted toward key performance indicator (KPI) processing for the network element based on the signaling received from the wireless device.

4. The base station of claim 1 ,

wherein the ARFCN field with a value of 0, the PCI field with a value of 0, and the measurement results field being empty form a custom signature configured to indicate to initiate SCG failure without counting the SCG failure towards key performance indicators (KPIs) for the base station.

5. The base station of claim 1 ,

wherein a first entry of a measResultFreqListNR-r15 information element (IE) received from the wireless device includes the signaling including the ARFCN field with a value of 0, the PCI field with a value of 0, and the measurement results field being empty.

6. A method, comprising:

by a base station:

decoding signaling received from a wireless device; and

determining that the signaling received from the wireless device includes a trigger for secondary cell group (SCG) failure based on the signaling including an absolute radio frequency channel number (ARFCN) field with a value of 0, a physical cell identity (PCI) field with a value of 0, and a measurement results field being empty.

7. The method of claim 6 , wherein the method further comprises:

performing a SCG failure procedure for the wireless device based on the signaling received from the wireless device.

8. The method of claim 6 ,

wherein the SCG failure is not counted toward key performance indicator (KPI) processing for the network element based on the signaling received from the wireless device.

9. The method of claim 6 ,

wherein the ARFCN field with a value of 0, the PCI field with a value of 0, and the measurement results field being empty form a custom signature configured to indicate to initiate SCG failure without counting the SCG failure towards key performance indicators (KPIs) for the base station.

10. The method of claim 6 ,

wherein a first entry of a measResultFreqListNR-r15 information element (IE) received from the wireless device includes the signaling including the ARFCN field with a value of 0, the PCI field with a value of 0, and the measurement results field being empty.

11. A network element, comprising:

an antenna;

a radio operably coupled to the antenna; and

a processor operably coupled to the radio;

wherein the network element is configured to:

establish a wireless link with a wireless device;

receive signaling from the wireless device; and

determine that the signaling received from the wireless device includes custom signaling based on inclusion of one or more specified values and fields of abstract syntax notation (ASN1) messages,

wherein the one or more specified values and fields of ASN1messages include an absolute radio frequency channel number (ARFCN) field with a value of 0.

12. The network element of claim 11 ,

wherein the custom signaling includes a request to trigger secondary cell group (SCG) failure for the wireless device.

13. The network element of claim 12 , wherein the network element is further configured to:

perform a SCG failure procedure based on the signaling received from the wireless device.

14. The network element of claim 13 ,

wherein the SCG failure is not counted toward key performance indicator (KPI) processing for the network element based on the signaling received from the wireless device.

15. The network element of claim 11 ,

wherein the one or more specified values and fields of ASN1messages include a physical cell identity (PCI) field with a value of 0.

16. The network element of claim 11 ,

wherein the one or more specified values and fields of ASN1messages include a measurement results field being empty.

17. The network element of claim 11 ,

wherein the network element includes a cellular base station.

18. A mobile device, comprising:

an antenna;

a radio operably coupled to the antenna; and

a processor operably coupled to the radio;

wherein the mobile device is configured to:

transmit signaling to a cellular base station, wherein the signaling transmitted to the cellular base station includes a trigger for secondary cell group (SCG) failure based on the signaling including an absolute radio frequency channel number (ARFCN) field with a value of 0, a physical cell identity (PCI) field with a value of 0, and a measurement results field being empty.

19. The mobile device of claim 18 ,

wherein the signaling transmitted to the cellular base station indicates to not count the. SCG failure toward key performance indicator (KPI) processing for the cellular base station.

20. The mobile device of claim 18 ,

wherein the ARFCN field with a value of 0, the PCI field with a value of 0, and the measurement results field being empty form a custom signature configured to indicate to initiate SCG failure without counting the SCG failure towards key performance indicators (KPIs) for the cellular base station.

21. The mobile device of claim 18 , wherein the mobile device is further configured to:

determine to trigger the SCG failure based at least in part on one or more reasons internal to the mobile device.

22. The mobile device of claim 21 ,

wherein the one or more reasons internal to the mobile device include one or more mobile device thermal constraints.

23. The mobile device of claim 21 ,

wherein the one or more reasons internal to the mobile device include power saving.

24. The mobile device of claim 18 ,

wherein a first entry of a measResultFreqListNR-r15 information element (IE) transmitted to the cellular base station includes the signaling including the ARFCN field with a value of 0, the PCI field with a value of 0, and the measurement results field being empty.
