摘要： A transmission/reception apparatus and method for reducing the amount of feedback information transmitted from a receiver in a multi-user MIMO system are provided. A transmitter determines a reference Channel Quality Information (CQI) and transmits the reference CQI to the receiver. Upon receipt of the reference CQI, the receiver compares the received reference CQI with a CQI of a stream received from the transmitter, sets a channel, over which the stream is received, to at least one of Activation and Inactivation, according to the comparison result, and transmits the set channel information to the transmitter. As a result, the receiver, even though it receives multiple streams from the transmitter, transmits to the transmitter the at least one of Activation and Inactivation information of the channel separately for each individual stream, thereby contributing to a reduction in the total amount of feedback information.

摘要： A multiple-input multiple-output (MIMO) communication method and apparatus are provided. A MIMO communication apparatus includes a selected beamforming vector determining unit to determine a selected beamforming vector corresponding to a selected user, a performance information generating unit to generate performance information corresponding to where a non-selected beamforming vector is allocated to a non-selected user, and an additional beamforming vector selecting unit to select an additional beamforming vector corresponding to the non-selected user based on the performance information.
