Abstract
Methods and apparatuses are disclosed that utilize information from less than all transmission paths from a transmitter to form beamforming weights for transmission. In addition, methods and apparatuses are disclosed that utilize channel information, such as CQI, eigenbeam weights, and/or channel estimates, to form beamforming weights.
