Abstract: A controller of a RAN detects an interferer is present in a region covered by antenna array(s) that provide a 3D view of segments of a cell, using at least a mapping from the segments to corresponding anomaly signatures, and using radio measurements taken in the segments, to determine segment(s) affected by the interferer. The controller performs mitigation of interference in the segment(s). A base station controlling the antenna array(s) determines that an event has been detected because radio measurement(s) of the segments of the cell meet an event detection threshold, and performs and sends to the controller multiple symbol-level radio measurements. The controller also causes channel sensing and radio measurements to be performed by the base station for steady state and states of interest in the cell. The controller correlates these radio measurements to map from segments to anomaly signatures and uses the mapping to perform interference mitigation.
