Patent ID: 8693422

Claim:
A subband scheduling method of an eNodeB in a wireless communication system, the method comprising: determining whether the eNodeB is in an overload state according to a used amount of a first radio resource of the eNodeB; if the eNodeB is not in the overload state, receiving information on a used amount of a second radio resource 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 according to the used amount of the second radio resource; if 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 according to the set number of subbands and the subband scheduling start order.
