FREQUENCY SPECTRUM MANAGEMENT DEVICE AND METHOD, ELECTRONIC DEVICE AND METHOD, AND WIRELESS COMMUNICATION SYSTEM

摘要

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.
