Title:
FREQUENCY MANAGEMENT DEVICE AND FREQUENCY MANAGEMENT METHOD FOR WIRELESS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/161280
Kind Code:
A1
Abstract:
[Problem] To provide a frequency management method and device, and a wireless system, with which it is possible to efficiently determine the allowable transmission power for a transmission station in a system on the interference-imparting side. [Solution] A frequency management device (50) receives a change notification for frequency-use conditions from a secondary transmission station (20_0) for changing the frequency-use conditions (S101, S102), and sets the allowable transmission power for the secondary transmission station (20_0) and for other secondary transmission stations (20_1, 20_3), for which at least a portion of the interference-attaining ranges thereof overlaps (S103, S104).
