The method includes: selecting a plurality of relay stations for transmitting a plurality of backhaul signals, and transmitting the plurality of backhaul signals to the selected respective relay stations by using different radio resources, wherein each of the selected relay stations configures a subframe for receiving each of the plurality of backhaul signals as the MBSFN subframe. Accordingly, the backhaul signal can be transmitted between the base station and the plurality of relay stations by effectively using the radio resources.
