On the other hand, a transmission side radio station has a notification signal measurerwhich measures a reception power level of the notification signal and detects the frequency notified by the signal, and a frequency band controllerwhich determines an assignable frequency band for a radio link between the transmission side radio station and the reception side radio station based on the radio signal data and the notification signal.
