    • Techniques for sending multiple-input multiple-output (MIMO) transmissions in wireless communication systems are described. In one design, a transmitter sends a first reference signal via a first link, e.g., a cell-specific reference signal via the downlink. The transmitter receives channel quality indicator (CQI) information determined by a receiver based on the first reference signal. The transmitter also receives a second reference signal from the receiver via a second link, e.g., a sounding reference signal via the uplink. The transmitter obtains at least one MIMO channel matrix for the first link based on the second reference signal. The transmitter determines at least one precoding matrix based on the at least one MIMO channel matrix, e.g., in accordance with ideal eigen-beamforming or pseudo eigen-beamforming. The transmitter then sends a data transmission to the receiver based on the at least one precoding matrix and the CQI information.
    • 描述了在无线通信系统中发送多输入多输出(MIMO)传输的技术。 在一种设计中,发射机经由第一链路发送第一参考信号,例如经由下行链路的小区特定参考信号。 发射机基于第一参考信号接收由接收机确定的信道质量指示符(CQI)信息。 发射机还经由第二链路从接收机接收第二参考信号,例如经由上行链路的探测参考信号。 发射机基于第二参考信号获得用于第一链路的至少一个MIMO信道矩阵。 发射机基于至少一个MIMO信道矩阵来确定至少一个预编码矩阵,例如,根据理想的本征波束形成或伪特征波束形成。 然后,发射机基于至少一个预编码矩阵和CQI信息向接收机发送数据传输。
