    摘要： An apparatus and a method manage power of a small base station. Whether a notify message indicating that a subscribed terminal enters a macro base station that includes an off-small base station is received from the macro base station under a closed access mode is determined. When the notify message is received, whether a service is providable to the subscribed terminal is determined. When the service is providable to the subscribed terminal, the small base station is turned on. During the closed access mode or when a load of a macro cell is large during an open access mode, when a terminal that should be serviced does not exist in the neighborhood of a small base station, an interference and power consumption unnecessarily generated may be reduced by turning off the small base station.

    摘要： 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.
