<P>PROBLEM TO BE SOLVED: To suppress increase in interference noises caused when relaying signal transmission by a relay station. <P>SOLUTION: In a transmission destination station 3, a transmission path, having a minimum total of required transmission power values of respective stations on a transmission path, is selected form among candidates for the transmission path from a transmission source station 1 to the station 3, and a pilot signal including identification information about the respective stations on the transmission path and required transmission power values is transmitted to the station 1 and a relay station 2. In this way, the stations 1 and 2 which have received this pilot signal can determined the transmission path having the minimum total of required transmission power values in signal transmission thereafter, by using the identification information included in the received pilot signal, and signals can be transmitted by transmission power defined by the required transmission power values included in the received pilot signal. <P>COPYRIGHT: (C)2003,JPO |
