A method of scheduling a subband is provided. The method includes determining whether the eNodeB is in an overload state according to a used amount of a first radio resource of the eNodeB, receiving information on a used amount of a second radio source of at least one neighbor eNodeB from the at least one neighbor eNodeB, determining whether the at least one neighbor eNodeB is in the overload state, setting a number of total subbands to be used for a subband scheduling to a number lower than a number of total subbands used by the at least one neighbor eNodeB, setting a subband scheduling start order such that the subband scheduling is started from a subband having a farthest distance in frequency from at least one subband used by the at least one neighbor eNodeB from among the set number of subbands, and performing the subband scheduling.
