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

Abstract

A frequency spectrum management device includes a processor configures to: adjust, in response to a coexistence management request from one or more secondary system apparatuses, current grouping of the one or more secondary system apparatuses according to a predetermined performance requirement, wherein the coexistence management request comprises at least information about available spectrum resources requested from a geographic location database by the one or more secondary system apparatuses according to the current grouping; determine, according to a result of the adjustment, regrouping information of the one or more secondary system apparatuses, so that the one or more secondary system apparatuses re-request the geographic location database for available spectrum resources according to the regrouping information; 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.

1 . A spectrum management device comprising:
 a memory configured to store a predetermined spectrum resource calculation manner and a processor configured to:   adjust, in response to a coexistence management request from each of a plurality of secondary system apparatuses and according to primary system interference reference point information, current grouping of the plurality of secondary system apparatuses according to a predetermined performance requirement, wherein the coexistence management request comprises at least information about available spectrum resources requested from a geographic location database by each of the plurality of secondary system apparatuses according to the current grouping;   determine regrouping information of the plurality of secondary system apparatuses;   sending, to the plurality of secondary system apparatuses, the regrouping information, so that the plurality of secondary system apparatuses re-request the geographic location database for available spectrum resources according to the regrouping information;   wherein the primary system interference reference point information is comprised in the coexistence management requests of the plurality of secondary system apparatuses or is obtained from the geographic location database; and   wherein the processor is further configured to calculate, according to the primary system interference reference point information, available spectrum resources for the plurality of secondary system apparatuses, and adjust, according to the calculated available spectrum resources and the predetermined performance request, the current grouping of the plurality of secondary system apparatuses.
