    摘要: The present disclosure relates to an electronic device, a spectrum management method, and a control method. According to one embodiment, an electronic device used for spectrum management comprises a processing circuit. The processing circuit is configured to acquire the interference relationships between radio access nodes managed by a first level spectrum management device, said radio access nodes comprising radio access nodes managed respectively by different second level spectrum management devices. The processing circuit is further configured to allocate, based on the acquired interference relationships, multiplex spectrum resources to radio access nodes that do not interfere with each other, and orthogonal spectrum resources to radio access nodes that do interfere with each other.
