    摘要: An apparatus and method are provided for beamforming in a MIMO wireless communication system. A base station includes a first calculator that repeatedly calculates downlink beamforming vectors of the user terminals to calculate the optimal beamforming vectors for the user terminals, a quantizer that quantizes the downlink beamforming vectors in order to transmit information of the downlink beamforming vectors, a control channel transmitter that feeds forward information of the quantized downlink beamforming vectors to the user terminals, a second calculator that calculates the final downlink beamforming vectors of the user terminals, and a beamforming transmitter that sums the beamformed TX signals of the user terminals and transmits the summed TX signals through a plurality of TX antennas.

    摘要: Disclosed are an apparatus and a method for determining a transmit/receive antenna in a Multiple Input Multiple Output (MIMO) communication system. At least one sub-channel matrix including transmit antenna information and receive antenna information is generated. From the at least one sub-channel matrix, a sub-channel matrixhaving a maximum value Frobenius norm is determined. The transmit and receive antenna information are then extracted from the determined sub-channel matrix.
