a report signal generation unit configured to collect information of the one or more characteristic data extracted from the received signal by the characteristic data extraction unit and to generate a report signal including the collected information; a control signal extraction unit configured to decode a control signal received from the opposing radio station and extract information of a characteristic data determined by the opposing radio station; a signal generation unit (204, 205) configured to convert any one of data signal and a signal for radio transmission including the report signal or both into a signal having a radio signal format of a radio access technique and to generate a transmission signal; wherein if the characteristic data has not been determined by the opposing radio station, then the radio signal format is a predetermined radio signal format; and the signal generation unit generates the transmission signal either by intentionally adding the statistical properties to the transmission signal so that the waveform of the transmission signal has a characteristic waveform based on a dedicated characteristic data indicating the transmission of the collected information, or by intentionally not adding the statistical properties of any characteristic data to the transmission signal; else the radio signal format corresponds to the characteristic data determined by the opposing radio station; and the signal generation unit generates the transmission signal by intentionally adding the statistical properties to the transmission signal so that the waveform of the transmission signal has a characteristic waveform based on the determined characteristic data;
