A wireless access point wirelessly serves User Equipment (UEs) with a wireless communication service using carrier aggregation and intermodulation interference mitigation. The wireless access point transfers user data to the UEs using carrier aggregation over a primary Long Term Evolution (LTE) band that transports LTE primary component carriers, secondary LTE bands that transport LTE secondary component carriers, and secondary Fifth Generation New Radio (5GNR) bands that transport 5GNR secondary component carriers. The wireless access point measures intermodulation interference in the secondary 5GNR bands. The wireless access point terminates at least some of the LTE secondary component carriers in the secondary LTE bands when the intermodulation interference in the secondary 5GNR bands exceeds an interference threshold.
