Zusammenfassung:Methods and systems are described for reducing interference on radio units from passive intermodulation (PIM) distortion. Base station radio units can have multiple antennas, each receiving and sending communications over various frequencies. Embodiments under the present disclosure can identify the source of PIM and then reduce power of the aggressor downlink carriers on the impacted antennas. This can reduce the PIM that desensitizes the uplink receivers.
