<p>In a radio communication system performing bidirectional communication between a base station having plural transmitting and receiving antennas and plural terminals using the same frequency via a relay station having plural transmitting and receiving antennas, the base station and terminals transmit signals to the relay station simultaneously in a first time frame, the relay station which receives the transmitted signals in the first time frame transmits signals generated by multiplying the received signals by a relay station transmission weight, to the base station and the plural terminals in a second time frame. With this, it is possible to provide a communication system and the like, which can realize MU-MIMO bidirectional communication between a base station including plural antennas and plural terminals, with a lower amount resources when the communication is performed via a relay station.</p> |
