    • The present invention enables assignment to a terminal a sub-band having satisfactory communication quality. A reference-signal reception unit receives from a terminal a reference signal spreading over sub-bands. A communication-quality measurement unit measures the communication quality of each of the sub-bands on the basis of the reference signal. A sub-band assignment unit assigns one of the sub-bands to the terminal on the basis of the communication quality, for the terminal to perform wireless communication with the communication device. A reference-signal transmission unit transmits to the communication device a reference signal spreading over the sub-bands. A sub-band-assignment-information reception unit receives information on one of the sub-bands which is assigned to the terminal by the communication device on the basis of the reference signal. A data transmission unit transmits data to the communication device through the sub-band assigned to the terminal.
    • 本发明能够使终端具有令人满意的通信质量的子带。 参考信号接收单元从终端接收在子频带上扩展的参考信号。 通信质量测量单元基于参考信号来测量每个子带的通信质量。 子带分配单元根据通信质量将一个子带分配给终端,以使终端与通信设备进行无线通信。 参考信号发送单元向通信设备发送在子频带上扩展的参考信号。 子带分配信息接收单元基于参考信号从通信设备接收分配给终端的子频带之一的信息。 数据发送单元通过分配给终端的子带向通信设备发送数据。
