RADIO SYSTEM, RADIO BASE STATION, AND MANAGEMENT APPARATUS
First Claim
1. A radio system comprising:
- a plurality of radio base stations for performing radio communications by using a channel among a plurality of channels;
a plurality of terminal devices for performing the radio communications with the radio base stations;
a retrieving unit for retrieving a terminal device which is closest to one of the radio base stations for each of one or more of the channels when determining a channel to be used by said one of the radio base stations; and
an instruction unit for instructing the terminal device retrieved by the retrieving unit to transmit a notification signal, andwherein said one of the radio base stations includes a channel determining unit configured to determine the channel to be used based on a reception state of the notification signal from the terminal device.

Abstract
A new base station transmits position information to a TVWSDB device and receives channel information of TV white space from the TVWSDB device. The TVWSDB apparatus instructs existing base stations to arrange that the respective CPE terminals that are the nearest in distance to the new base station perform CBP bursts for channels reported to the new base station. The CPE terminals then perform the CBP bursts according to a schedule established for the existing base stations. The new base station searches for and finds a cell having the same standard as itself on the basis of the burst signals of the CPE terminals and shares the channel of the cell having the same standard as itself with the existing base stations.
