<P>PROBLEM TO BE SOLVED: To enable use of a unidirectional link in a radio communication system using white space. <P>SOLUTION: A radio communication system 1 includes a transmission station (10) for transmitting data by radio communication and reception stations (21, 22) for receiving transmitted data, so as to perform radio communication using white space. Each reception station (21, 22) detects that data can be received at a particular frequency, and transmits the detected result, that is communication quality information, to the transmission station (10). The transmission station (10) receives and retains the communication quality information. When starting data reception by radio communication, the reception station (21, 22) transmits requested quality, which is a condition when receiving data, to the transmission station (10). By referring to the communication quality information, the transmission station (10) determines a frequency that satisfies the requested quality, and allocates the frequency to be a frequency when transmitting data to the reception station (21, 22). <P>COPYRIGHT: (C)2013,JPO&INPIT |
