Abstract

Apparatuses, methods, and systems are disclosed for model based predictive interference management. One method includes receiving at least one monitoring report from a device. The method includes determining a monitoring event report based on a subscription and the at least one monitoring report. The method includes providing the providing the monitoring event report to an application.

Claims (37)

1 . A method performed by a network function, the method comprising:

receiving, from a radio access network (RAN) intelligent controller (RIC), at least one monitoring report from a device, wherein the at least one monitoring report comprises one or more of radio resource utilization information, quality-of-service (QoS) information, or backhaul information;

determining a monitoring event report indicating that a performance metric for a user equipment (UE) or the device has changed, wherein the monitoring event report is determined based on a subscription and the at least one monitoring report; and

providing the monitoring event report to an application.

2 . The method of claim 1 , further comprising:

receiving a predictive inter-cell interference management policy from the application;

determining at least one radio parameter corresponding to the predictive inter-cell interference management policy; and

transmitting the at least one radio parameter based on the predictive inter-cell interference management policy to the device.

3 . The method of claim 2 , wherein the predictive inter-cell interference management policy comprises one or more of a cell identifier (ID), an application ID, a group of UE IDs, a network slice ID, a central unit (CU) ID, a distributed unit (DU) ID, a current policy ID, a new policy ID, a current traffic steering policy ID, a new traffic steering policy ID, a confidence level parameter, an enforcement flag, a time validity indicator, or an area indicator.

4 . The method of claim 2 , wherein the at least one radio parameter comprises one or more of an overload indication, a high interference indication, a relative narrowband transmit power, almost blank subframe pattern information, a coordinated multipoint coordination area, a coordinated multipoint scheme, a resource restriction, a handover request indication, a source cell ID, a target cell ID, a frequency selection indication, a radio access technology selection indication, a radio interface selection indication, a distributed unit selection indication, or a central unit (CU) selection indication.

5 . The method of claim 2 , wherein the predictive inter-cell interference management policy is provided to the device via an application exposure function.

6 . The method of claim 1 , further comprising receiving a subscription request for the subscription from the application.

7 . The method of claim 1 , wherein the monitoring event report comprises one or more of a cell identifier (ID), a UE ID, a network slice ID, a resource ID, a resource pool ID, a UE quality of experience downgrade indication, a UE quality of service downgrade indication, a high resource load indication, a high radio access network delay indication, a low backhaul resource availability indication, a quality of service fluctuation indication, a radio link failure indication, a bandwidth adaptation requirement, a radio resource adaptation requirement, or a traffic steering requirement.

8 . An apparatus for performing a network function, the apparatus comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the apparatus to:

receive, from a radio access network (RAN) intelligent controller (RIC), at least one monitoring report from a device, wherein the at least one monitoring report comprises one or more of radio resource utilization information, quality-of-service (QoS) information, or backhaul information;

determines a monitoring event report indicating that a performance metric for a user equipment (UE) or the device has changed, wherein the monitoring event report is determined based on a subscription and the at least one monitoring report; and

provides the monitoring event report to an application.

9 . A method performed by a network function, the method comprising:

receiving a predictive inter-cell interference management policy from at least one application, wherein the predictive inter-cell interference management policy comprises interference mitigation parameters comprising an enforcement flag, a time validity window, and priority information and associated enforcement conditions;

determining, based on the predictive inter-cell interference management policy and a radio resource condition, at least one radio parameter for configuring a radio access network (RAN) node, wherein determining comprises selecting resource allocation parameters from a set of pre-defined interference management schemes; and

transmitting the at least one radio parameter to a middleware function or to the RAN node, wherein the at least one radio parameter is used to configure the RAN node for interference mitigation over a time interval.

10 . The method of claim 9 , wherein the predictive inter-cell interference management policy comprises one or more of a cell identifier (ID), an application ID, a group of UE IDs, a network slice ID, a central unit (CU) ID, a distributed unit (DU) ID, a current policy ID, a new policy ID, a current traffic steering policy ID, a new traffic steering policy ID, a confidence level parameter, an enforcement flag, a time validity indicator, or an area indicator.

11 . The method of claim 9 , wherein the at least one radio parameter comprises one or more of an overload indication, a high interference indication, a relative narrowband transmit power, almost blank subframe pattern information, a coordinated multipoint coordination area, a coordinated multipoint scheme, a resource restriction, a handover request indication, a source cell ID, a target cell ID, a frequency selection indication, a radio access technology selection indication, a radio interface selection indication, a distributed unit selection indication, or a central unit (CU) selection indication.
