Abstract: PURPOSE: A method and apparatus for reducing interference between heterogeneous networks using a beam forming method are provided to offer PMI(Pre-coding Matrix Index) information to a macro base station based on the PMI information received from a femto base station. CONSTITUTION: A femto terminal receives a threshold value for an SINR(Signal-to-Interference plus Noise Ratio) and a threshold value for the reception power of a macro base station from a femto base station(500). The femto terminal measures a signal strength or the DL(DownLink) channel power of the macro base station which is close to the SINR(502). When a condition(SINR TH_2) is satisfied, the femto terminal gives feedback on a main eigenvector of the measured Tx covariance matrix to the femto base station(504). The femto terminal receives information for the macro base station(506).
