<P>PROBLEM TO BE SOLVED: To provide a radio communication method and a radio communication system that can curb the number of frequency channels in which frequency repetition is performed to effectively use frequency resources by establishing an uplink interference canceller technology feasible in an operation amount and a circuit scale. <P>SOLUTION: A radio communication method determines whether an interference component is large or small, and if the interference component is small, transmits an estimation signal to another control station, and if the interference component is large, stops transmitting as the estimation signal. The control station having received the estimation signal generates a replica of an interference signal from the estimation signal, and cancels it out from the received signal. Because the replica used for cancellation of the interference signal has only small interference components, it allows accurate interference cancellation. Furthermore, regarding a signal which has a large interference component, the interference cancellation makes the interference component smaller. By applying the same processing to a signal about which interference has been cancelled, and repeating the processing, interference cancellation using a replica signal including a large interference component is avoided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
