Spectrum management device and method, geographic location database and secondary system

Abstract

The invention provides a spectrum management device and method, a geographic location database, a coexistence discovering device and a secondary system which are applied to a wireless communication system comprising a master system and the secondary systems. The spectrum management device comprises a processing circuit which is configured to obtain spectrum usage information and spectrum adjustment capability information of the secondary systems managed by the spectrum management device, wherein the spectrum usage information corresponds to related information of usage spectrums allocated to the secondary systems, and the spectrum adjustment capability information corresponds to the related information of whether the secondary systems support spectrum adjustment operation or not. The processing unit is also configured to determine spectrum adjustment for the secondary systems managed by the spectrum management device based on the spectrum usage information and the spectrum adjustment capability information, so the interference on the master system resulting from the spectrum usage of the secondary systems is controlled within an allowed range of the master system. According to the spectrum management device and method, the geographic location database, the coexistence discovering device and the secondary system provided by the invention, spectrum resources can utilized efficiently.

Description

technical field [0001] The present disclosure relates to the management of spectrum resources in wireless communication, and in particular to a spectrum management device, a spectrum management method, a geographic location database, a secondary system and a wireless communication method for a wireless communication system including a primary system and a secondary system. Background technique [0002] With the rapid development of computer and communication technology, the global information network is rapidly evolving to the next generation network (Next Generation Network, NGN) based on the interconnection protocol (IP) between networks. An important feature of the next generation network is that multiple wireless technologies coexist to form a heterogeneous wireless access network, where the heterogeneous wireless access networks have different priorities in using spectrum resources. Spectrum management involves two parts: a primary system (Primary System) and a secondar...

AI Technical Summary

Problems solved by technology

With the operation of the network, the status of each system is constantly changing, and the resource utilization rate of the spectrum resource allocation results is getting lower and lower, which leads to the inability to access more systems without reaching the capacity limit

In order to solve the above problems, a simple method is to re-allocate resources and system configurations for all subsystems, but this way of reconfiguring a large number of subsystems will bring very high overhead
