Radio communication system, menagement device and base station menagement method

Abstract

In a radio communication system of the embodiment, a base station (2) comprises a UL interference information supply part (24) for sending the UL interference information of an uplink signal from a terminal (1) to the base station (2), the terminal (1) comprises a DL interference information supply part (12) for sending the DL interference information of a downlink signal from the base station (2) to the terminal (1). A management device (3) comprises lists (34, 35, 37) possessing an operation frequency of the base station (2), a frequency band width and the sending output, an interference information obtaining part (32) for obtaining the UL interference information and the DL interference information, a frequency / sending outputting control part (33) for distributing the operation frequency, the frequency band width and the sending output based on the UL interference information, the DL interference information and the lists (34, 35, 37).

Description

[0001] This application is based on Japanese Patent Application No. 2012-163121 (filing date: July 23, 2012), and enjoys the priority of this application. This application contains the entire contents of this application by reference to this application. technical field [0002] Embodiments of the present invention relate to a wireless communication system, a management apparatus, and a base station management method for managing a plurality of base stations. Background technique [0003] With the popularization of smartphones and tablet terminals, it is expected that mobile data traffic will gradually increase in the future. As a measure against indoor traffic, it is considered to install a femtocell base station or a small cell base station. However, the coverage area of ​​one base station is small, a large number of base stations need to be installed, and the burden of station design and installation engineering is large. Important setting values ​​determined in the sta...

AI Technical Summary

Problems solved by technology

When an indoor area such as a building is assumed, in this method, different operating frequencies are selected for base stations with the same longitude and latitude but different heights, and the frequency utilization efficiency may deteriorate.

In addition, the transmission environment may change due to the environment such as indoor occluders

Therefore, it is impossible to set an appropriate operation frequency and transmission output only by information of longitude and latitude, and there is a problem that frequency utilization efficiency deteriorates.
