Abstract

A method and an apparatus for controlling interference between a microcell and a macrocell in a home base station within the microcell are provided in the present invention. In particular, in the case that the existence: of at least one victim macro user equipment is detected, the home base station according to the present invention controls its transmit power within an interval determined by an upper limit and a lower limit, such that it can be guaranteed that the performance requirement of a communication with the home user equipment is satisfied while lac interference toward the victim macro user equipment is reduced. Additionally, the home base station according to the present invention detects whether there is at least one indoor victim macro user equipment, and conducts corresponding interference control according to the detection result.
