Abstract:
A base station which is able to perform radio communications with a relay station and a mobile station, the base station includes a transmitter configured to transmit radio signals to the relay station in downlink backhaul subframes, and to limit transmission of radio signals to the relay station in subframes other than the downlink backhaul subframes; and a controller configured to allow, when performing a random access procedure to the relay station, the transmitter to transmit a message of the random access procedure even in the subframes other than the downlink backhaul subframes.
