US 10,952,080 B2 · Spectrum management device and method, geographic location database and subsystem

Abstract

Provided in the present disclosure are a spectrum management device and method, a geographic location database, a coexistence discovery device, and subsystems for use in a radio communication system comprising a main system and subsystems. The spectrum management device comprises: a processing circuit, which is configured to: acquire spectrum usage information and spectrum adjustment capability information of subsystems managed by the spectrum management device, the spectrum usage information corresponding to information related to used spectrums assigned to and used by each subsystem, the spectrum adjustment capability information corresponding to information related to whether the subsystems support a spectrum adjustment operation, and an adjustment of the spectrums of the subsystems managed by the spectrum management device is determined on the basis of the spectrum usage information and the spectrum adjustment capability information, thus the interference caused by the subsystems as a result of spectrum usage to the main system is limited within a permissible range of the main system. The spectrum management device and method, the geographic location database, the coexistence discovery device, and the subsystems of the present disclosure achieve highly efficient use of spectrum resources.

Dependent claims

A spectrum management device for a wireless communication system comprising a primary system and a cognitive radio system, the spectrum management device comprising:

a processing circuit configured to:
acquire spectrum usage information and spectrum transition capability information of the cognitive radio system managed by the spectrum management device, wherein the spectrum usage information corresponds to information on a usage spectrum allocated for use by each cognitive radio system, and the spectrum transition capability information comprises information on whether the cognitive radio system supports a spectrum transition operation, wherein a value of the spectrum transition capability information is indicated by a Boolean value;
and
determine spectrum transition to each cognitive radio system managed by the spectrum management device based on the spectrum usage information and the spectrum transition capability information, so that interference caused by spectrum usage of cognitive radio system to the primary system falls within a permissible range of the primary system.
