Abstract

The invention provides a frequency spectrum management device and method, an electronic device and a wireless communication system. The frequency spectrum management device comprises a processor, wherein the processor is configured to adjust current grouping of one or more subsystem devices according to a predetermined performance requirement in response to a coexistence management request from the one or more subsystem devices, wherein the coexistence management request at least comprises information about an available frequency spectrum resource requested by the one or more subsystem devices from a geographic position database according to the current grouping, adjust re-grouping information about the one or more subsystem devices according to a result of the adjustment so as to enable the one or more subsystem devices to re-request an available frequency spectrum resource from the geographic position database according to the re-grouping information, and optimize the frequency spectrum usage of the one or more subsystem devices according to the available frequency spectrum resource re-requested by the one or more subsystem devices. According to the embodiment of the invention, the frequency spectrum utilization rate can be optimized, and the system performance can be improved.

Description

technical field [0001] The present disclosure generally relates to the technical field of wireless communication, and more particularly, to a spectrum management device and method, an electronic device and method, and a wireless communication system, which optimize the grouping of secondary system devices so that the secondary system devices request available spectrum resources to optimize spectrum utilization efficiency. Background technique [0002] With the development of wireless communication technology, spectrum resources are becoming more and more tense, and existing research shows that the utilization rate of allocated licensed spectrum resources is generally not high. Cognitive radio technology, as an intelligent evolution of software radio technology, is a A key technology to improve the actual utilization of spectrum. Although the introduction of cognitive radio technology can improve the problem of limited spectrum resources, since different modulation signals a...
