Frequency spectrum management device and method, electronic device and method, and wireless communication system

An electronic device in a secondary system apparatus, the electronic device comprising:

• a processor configured to:
• generate a coexistence management request to be sent to a spectrum management device, the coexistence management request comprising at least information about available spectrum resources requested from a geographic location database by the secondary system apparatus according to current grouping;
• re-request, according to regrouping information from the spectrum management device, the geographic location database for available spectrum resources, the regrouping information being generated by adjusting the current grouping of the secondary system apparatus by the spectrum management device in response to the coexistence management request according to a predetermined performance requirement;
• and
• control, based on spectrum utilization optimization process performed by the spectrum management device according to the available spectrum resources re-requested by the secondary system apparatus, the secondary system apparatus to operate in allocated spectrum resources.

An electronic device in a proxy apparatus, the electronic device comprising:

• a processor configured to:
• re-request, in response to a spectrum request from one or more secondary system apparatuses, a geographic location database for available spectrum resources for the one or more secondary system apparatuses in groups, wherein the one or more secondary system apparatuses are re-grouped by a spectrum management device according to a coexistence management request from the one or more secondary system apparatuses and a predetermined performance requirement, the coexistence management request comprising at least information about available spectrum resources requested from the geographic location database by the one or more secondary system apparatuses according to current grouping;
• and
• determine a spectrum response comprising the available spectrum resources re-requested from the geographic location database so as to notify the one or more secondary system apparatuses.

A wireless communication system comprising:

• a geographic location database;
• one or more secondary system apparatuses configured to:
• generate a coexistence management request to be sent to a spectrum management device, the coexistence management request comprising at least information about available spectrum resources requested from the geographic location database by the one or more secondary system apparatuses according to current grouping,
• re-request, according to regrouping information from the spectrum management device, the geographic location database for available spectrum resources, and
• operate in allocated spectrum resources based on spectrum utilization optimization process performed by the spectrum management device according to the available spectrum resources re-requested by the one or more secondary system apparatuses;
• and
• the spectrum management device configured to:
• adjust, in response to the coexistence management request, the current grouping of the one or more secondary system apparatuses according to a predetermined performance requirement,
• determine, according to a result of the adjustment, the regrouping information of the one or more secondary system apparatuses, and
• optimize, according to the available spectrum resources re-requested by the one or more secondary system apparatuses, spectrum utilization of the one or more secondary system apparatuses.
