Abstract

The present invention relates to an apparatus and a method for transmitting interference control information between heterogeneous cells. The present invention discloses a base station comprising: a signal reception unit for receiving wireless network information including an additional ABS pattern, which indicates whether a subframe, in which a synchronization signal transmission from a base station is scheduled, based on time division multiplexing, is a subframe (ABS) in which the transmission power of the synchronization signal is reduced so as not to cause interference with a heterogeneous base station; a measurement unit for measuring the signal which is received by the heterogeneous base station; and a power adjustment unit for adjusting the transmission power of the synchronization signal based on the measured signal and the additional ABS pattern. According to the present invention, interference between synchronization cells, which is generated between the heterogeneous cells, is reduced, and error in searching and selecting a cell, which is accessible by a user equipment in a resting state not having a femtocell membership, can also be reduced.
