    摘要： A system and method for feeding back channel information are provided. A method for communications device operations includes generating feedback information, encoding the feedback information to produce a feedback payload, and transmitting the feedback payload to a communications server serving a communications device. The feedback information includes at least a first long term wideband channel statistics and a second long term wideband channel statistics.

    摘要： A system and method for reporting quantized feedback information for adaptive codebooks include generating channel state information, encoding all or part of the channel state information to produce a feedback payload and transmitting the feedback payload to a base station from a mobile station. The channel state information comprises a rank indicator, a first matrix indicator, a wideband channel quality indicator, a second matrix indicator and at least one narrowband channel quality indicator. When the rank indicator is greater than 1, the first matrix indicator is reported in a second report. On the other hand, when the rank indicator is equal to 1, the content of the first matrix indicator is split between a second report and a third report.

    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.
