The apparatus and method for beamforming downlink transmission smart antenna in the mobile communication

摘要

A base station apparatus including an antenna array calculates a direction of a weight vector of a transmission beam so as to maximize in-phase component power for a common channel signal in a transmission channel signal for transmission to a mobile station and to minimize the sum of quadrature-phase power component and interference power for other mobile stations inside and outside a cell due to a transmission channel signal for the mobile station.
