Method and device for setting backhaul link subframe in wireless communication system having carrier aggregation technique applied thereto
Disclosed in the present invention is a method for a base station to set a backhaul link subframe for a relay node in a wireless communication system, to which a carrier aggregation technique is applied. More particularly, the present invention comprises the steps of: determining one of the plurality of subframe settings as a first subframe setting for a main component carrier allocated to the relay node; composing subframe setting candidates for one or more subcomponent carriers allocated to the relay node, on the basis of the determined first subframe setting; and determining a second subframe setting for each of the one or more subcomponent carriers, using the composed subframe setting candidates, wherein a subframe aggregation according to the first subframe setting and subframe aggregations according to each of the subframe setting candidates do not overlap when downlink subframes and uplink subframes of the different component carriers are identical, and a downlink subframe aggregation according to the second subframe setting is included in a downlink subframe aggregation according to the first subframe setting.
