The present invention relates to a method for allocating a resource which enables a relay node to transmit uplink control information to a base station in a wireless communication system. Specifically, the method for allocating the resource include the steps of: generating a control information sequence for a backhaul downlink sub-frame between a relay node and a base station; setting symbols for mapping the control information sequence when a plurality of symbols are punctured at a front end or a rear end of a backhaul uplink sub-frame between the relay node and the base station; and performing the time-first-mapping for the control information sequence with respect to resource elements corresponding to the set symbols in a descending order of sub-carrier indexes.
