Summary:PURPOSE: A beam forming apparatus in an MIMO wireless communication system based on the hybrid division duplex is provided to generate a pre-processing vectors and coupling vectors. CONSTITUTION: A base station apparatus in an MIMO wireless communication system comprises an estimator(420), a processor, and a controller(430). The estimator estimates the channel matrix of at least one terminal complying with the TDD(Time Division Duplex) mode. The processor confirms principal vector information of the channel matrix fed back from a terminal complying with the FDD(Frequency Division Duplex) mode. The controller calculates precoding vectors of terminals by using the channel matrix and principal vector.
