摘要： A frequency spectrum management device includes a processing circuit and is configured so that: a first subsystem manages the frequency spectrum management device, an allocation coefficient between other subsystems and the first subsystem is determined on the basis of the distances from the first subsystem and the other subsystems to a main system, the allocation coefficient expresses the degree of interference of aggregated interference that the other subsystems and the first subsystem produce with respect to the main system; and a frequency spectrum resource is allocated to the first subsystem on the basis of the allocation coefficient. The use of the frequency spectrum management device, the electronic device, and the method executed thereby of the present disclosure increases the degree of rationality of frequency spectrum resource allocation for the subsystems.
