Abstract

Architectures and techniques are described that can provide interference mitigation techniques by leveraging rApps the execute on a non-real time radio access network intelligent controller (non-RT RIC). One or more rApps can operate to assist in interference detection as well as interference avoidance. The interference detection rApp can determine a recommended threshold based on longer term trends or patterns, which can be used by an associated xApp executing on a near-real time radio access network intelligent controller (near-RT RIC) that typically lacks such capability. The interference avoidance rApp can determine a recommended slot to ban based on longer term trends or patterns, which can be used by an associated xApp or scheduler. For instance, the scheduler can use the slot banning recommendation from either the rApp or the xApp.

Dependent claims

A device, comprising:

at least one processor;
and
at least one memory that stores executable instructions that, when executed by the at least one processor, facilitate performance of operations, comprising:
receiving, via a threshold rApp of a non-real time radio access network intelligent controller (non-RT RIC), history data comprising cell history data indicative of cell status information for a cell over a configurable period of time greater than one second and user equipment (UE) history data indicative of UE measurements reported to the cell over at least a portion of the configurable period of time;
based on at least the history data, determining, via the threshold rApp, a threshold update for a threshold determined by an interference detection xApp executing on a near-real time radio access network intelligent controller (near-RT RIC);
and
transmitting the threshold update to the interference detection xApp,
wherein the determining of the threshold update comprises determining at least two Eigenvectors from at least two metrics of the UE history data.

A device, comprising:

at least one processor;
and
at least one memory that stores executable instructions that, when executed by the at least one processor, facilitate performance of operations, comprising:
receiving, via a slot rApp of a non-real time radio access network intelligent controller (non-RT RIC), history data comprising UE continuous quality improvement (CQI) measurements reported to a cell over intervals of a defined period of time;
determining, via the slot rApp, respective CQI scores for respective time slots, wherein a CQI score of the respective CQI scores is indicative of measured CQIs across different frequency sub bands over an interval of the intervals;
determining, via the slot rApp, a recommended slot to ban during the interval based on the CQI score being the lowest among the respective CQI scores;
and
transmitting the recommended slot to an interference detection xApp or a scheduler executing on a near-real time radio access network intelligent controller (near-RT RIC).
