Framework for supporting custom signaling between a wireless device and a cellular network
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.
1. An apparatus, comprising:
a processor configured to:
determine to trigger secondary cell group (SCG) failure; and
in response to the determination to trigger SCG failure, instruct a radio operably coupled to the processor to transmit, to a cellular network, signaling including:
a physical cell identity (PCI) field with a value of 0; and
a measurement results field, the measurement results field being empty.
2. The apparatus of claim 1 , wherein the signaling further includes an absolute radio frequency channel number (ARFCN) field with a value of 0.
3. The apparatus of claim 1 , further comprising the radio operably coupled to the processor, the radio configured to transmit the signaling.
4. The apparatus of claim 1 , wherein the signaling indicates to initiate SCG failure without counting the SCG failure towards key performance indicators (KPIs) for a base station.
5. The apparatus of claim 1 , wherein the signaling comprises a first entry of a measResultFreqListNR-r15 information element (IE).
6. An apparatus, comprising:
a processor configured to cause a user equipment (UE) to:
establish a wireless link with a cellular network;
determine to initiate secondary cell group (SCG) failure; and
transmit, to the cellular network, custom signaling, the custom signaling including a unique signature indicating to initiate the SCG failure.
7. The apparatus of claim 6 , wherein the custom signaling is identifiable as being associated with a custom signaling framework based on inclusion of one or more specified values or fields of abstract syntax notation (ASN1) messages.
8. The apparatus of claim 7 , wherein the one or more specified values or fields of ASN1 messages include a physical cell identity (PCI) field with a value of 0.
9. The apparatus of claim 7 , wherein the one or more specified values or fields of ASN1 messages include a measurement results field being empty.
10. The apparatus of claim 7 , wherein the one or more specified values or fields of ASN1 messages include an absolute radio frequency channel number (ARFCN) field with a value of 0.
11. The apparatus of claim 6 , wherein the custom signaling indicates to initiate SCG failure without counting the SCG failure towards key performance indicators (KPIs) for a base station.
12. The apparatus of claim 6 , wherein the determination to trigger SCG failure is based on a thermal constraint.
13. The apparatus of claim 6 , wherein the determination to trigger SCG failure is based on power saving.
14. The apparatus of claim 6 , further comprising a radio operably coupled to the processor.
15. A method, comprising:
at a cellular network:
establishing a wireless link with a user equipment (UE); and
receiving, from the UE, a message according to a first custom signaling framework, the message including:
a physical cell identity (PCI) field with a value of 0; and
a measurement results field, the measurement results field being empty.
16. The method of claim 15 , wherein the message is identifiable as being associated with the first custom signaling framework based on inclusion of one or more specified values or fields of abstract syntax notation (ASN1) messages.
17. The method of claim 16 , wherein the one or more specified values or fields of ASN1 messages include the measurement results field being empty.
18. The method of claim 16 , wherein the one or more specified values or fields of ASN1 messages include the PCI field with the value of 0.
19. The method of claim 15 , wherein the message comprises a first entry of a measResultFreqListNR-r15 information element (IE).
20. The method of claim 15 , wherein the message indicates to initiate secondary cell group (SCG) failure without counting the SCG failure towards key performance indicators (KPIs) for a base station.
