Patent ID: 8320836

Claim:
A radio communications system including a network connecting radio station and a counterparty radio station, the network connecting radio station being a radio station connected to a network and the counterparty radio station being in radio communications with the network connecting radio station, wherein the network connecting radio station includes an information obtaining unit which obtains information indicating a radio communications condition of one or more radio stations surrounding the network connecting radio station from the one or more surrounding radio stations via the network, the information indicating the radio communications condition of the radio station including information on a frequency used by the radio station and information on a waveform feature amount which exhibits a statistical characteristic of a signal waveform transmitted by the radio station; an information reporting unit which reports, to the counterparty radio station, all or some of information indicating a radio communications condition obtained from the surrounding radio station; and a radio resource parameter determining unit which determines, based on the information indicating the radio communications condition of the surrounding radio station and information on a measured value of the waveform feature amount that is reported from the counterparty radio station, whether communications can be conducted between the network connecting radio station and the counterparty radio station, and a radio resource parameter to be used when the communications are permitted, wherein the counterparty radio station includes a waveform information extracting unit which calculates, for each of one or more waveform feature amounts reported from the network connecting radio station, the measured value of the waveform feature amount of a signal received from another of the radio stations; and a received status reporting unit which reports, to the network connecting radio station, a measured value of the waveform feature amount calculated at the waveform information extracting unit.
