1. A device operating as an aerial base station in a radio access network (RAN), comprising:
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
receiving a handover request from a terrestrial base station that is configured to communicate with user equipment (UE) in an additional coverage zone, wherein the additional coverage zone at least partially overlaps a first coverage zone of the aerial base station;
determining an action to reduce potential interference between the device and the terrestrial base station, wherein the action includes selecting a downlink frequency for the device, changing an altitude of the device, changing a latitude or longitude of the device, changing a transmit power of the device, modifying the first coverage zone, or any combination thereof;
performing the action to reduce potential interference between the device and the terrestrial base station; and
accepting the handover request.
