摘要: Techniques for sending multiple-input multiple-output (MIMO) transmissions in wireless communication systems are described. In one design, a transmitter sends first reference signal via link, e.g., cell-specific the downlink. The receives channel quality indicator (CQI) information determined by receiver based on signal. also second from sounding uplink. obtains at least MIMO matrix link determines precoding matrix, accordance with ideal eigen-beamforming or pseudo eigen-beamforming. then data transmission to and CQI information.
