Abstract: A method and corresponding system to help manage carrier-aggregation service in view of possible intermodulation distortion between component carriers. When a base station is serving a UE with carrier aggregation service on at least two component carriers, the base station determines that uplink communication on the two component carriers is likely to combine to produce an intermodulation product that falls within the downlink channel of one of the component carriers, and that the power level of that intermodulation product is likely to be threshold high. In response, the base station then modifies the set of component carriers on which the base station provides the UE with carrier aggregation service, to help reduce or avoid associated intermodulation distortion.
