There is provided a method for allocating subframes in a radio communications system that performs communication by using a radio frame including a plurality of subframes, the method including: selecting a backhaul downlink subframe in which a base station is to transmit a signal to a relay station; and allocating the backhaul downlink subframe to a substitution subframe which is not limitation subframes, when the selected backhaul downlink subframe corresponds to one of the limitation subframes, wherein the limitation subframes are subframes in which the relay station is to transmit essential information to a relay user equipment. Therefore, it is possible to overcome a limitation that is present in a link between the base station and the relay station, perform an HARQ operation, and improve the efficiency of radio resource allocation. |
