Methods, systems, and devices are described for wireless communication. A method may include maintaining a plurality of conflict entries, each conflict entry indicating a first frequency range associated with interference by a first radio access technology (RAT) and a second frequency range associated with interference by a second RAT. Each conflict entry may indicate a first frequency range of component carriers of a RAT operating in carrier aggregation mode. Active coexistence conflicts may be identified between the first and second RATs based in part on the conflict entries and current radio conditions. The method may also include selecting one of the active coexistence conflicts for conflict mitigation. In some examples, a subset of the conflict entries are organized into an intermodulation group. The method may also include determining a conflict priority for each conflict entry associated with an active coexistence conflict. In some examples, conflict priorities may be aggregated.
