A relay station transmits a message to a wireless base station which allocates an up direction channel to notify a demand frequency band when receiving one of a signal train out of a predetermined signal group from a terminal device and also allocates a transmitting frequency band to the terminal device in accordance with a frequency band notified by the terminal device. The relay station, which is provided with a transmitting unit for transmitting a specific signal train not included in the predetermined signal group, is characterized in that the transmitting frequency band is allocated from the wireless base station without the benefits of allocation of an up direction channel to notify the demand frequency band. |
