Electronic device and method for wireless communication, and computer readable storage medium

An electronic apparatus for wireless communications, comprising:

• processing circuitry, configured to
• determine, based on information of interference relationship among secondary systems within a specific region, a second secondary system in a second coexistence group which has an interference relationship with a first secondary system in a first coexistence group, wherein the first coexistence group comprises secondary systems managed by a first spectrum management device, and the second coexistence, group comprises secondary systems managed by a second spectrum management device,
• determine, according to an interference relationship map, a spectrum utilization freedom degree of the first secondary system, wherein the spectrum utilization freedom degree of the first secondary system indicates a degree to which the first secondary system is capable of freely selecting spectrum resources among the spectrum resources allocated to the first coexistence group, and
• generate a spectrum coordination request to be provided to the second spectrum management device, the spectrum coordination request indicating that the first spectrum management device expects to coordinate utilization of spectrum resources with the second spectrum management device.
