A Long Term Evolution (LTE) access node to serve User Equipment (UEs) with a wireless Carrier Aggregation (CA) data communication service. A data processing system schedules CA Primary Component Carriers (PCCs), CA intra-band Secondary Component Carriers (SCCs) and CA inter-band SCCs for the UEs. A wireless transceiver wirelessly exchanges user data with the UEs based on the scheduling to serve the UEs with the CA PCCs, the CA intra-band SCCs, and the CA inter-band SCCs. The data processing system detects that a number of the UEs exceeds a UE threshold, and in response, identifies the UEs that use an LTE channel for their CA inter-band SCCs but not for their CA PCCs. The data processing system disables the LTE channel for the UEs that use the LTE channel for their CA inter-band SCCs but not for their CA PCCs.
