A method for allocating a downlink control channel in a fractional frequency reuse (FFR) system, includes: dividing a service frequency band of the system into a plurality of frequency partitions including a first frequency partition corresponding to a first frequency reuse factor, a second frequency partition corresponding Kth frequency reuse factor, and a third frequency partition; setting a transmission power level for each of the plurality of divided frequency partitions; allocating a downlink common control channel including non-user specific (NUS) control information common to every user to a particular frequency partition corresponding to the highest transmission power level among the set transmission power levels; and transmitting the NUS control information through the particular frequency partition.
