Abstract:
1. A wireless communication system for a multi-hop connection, which performs signal transmission between a source station, a plurality of relay stations and a destination station, comprising: the source station, including a transmission unit configured to transmit a pilot signal including identification information of the source station; a relay station of the plurality of relay stations including: the transmission unit of the relay station transmits a relay pilot signal at a transmission power prescribed in respective transmission power values, respectively, the reception unit includes a received SIR measurement unit configured to measure a received SIR obtained when receiving the received pilot signal, the required transmission power total calculation units include a power value calculation sub-unit configured to calculate a required transmission power value in an immediately preceding station, from which the at least one of the received pilot signal and the relay pilot signal is transmitted, by use of at least one of a transmission power value of the immediately preceding station, the measured received SIR and a desired received SIR, and a total calculation sub-unit configured to calculate a total of required transmission power values of respective stations on the transmission path by use of required transmission power values included in the at least one of the received pilot signal and the relay pilot signal and the required transmission power value calculated by the power value calculation sub-unit.
