Summary:A method for providing multiple-user multiple-input and multiple-output in a high-speed packet access system is described. Channel quality indicators are received from a plurality of dual stream capable wireless communication devices. A preferred beam and a secondary beam are determined for each wireless communication device using the channel quality indicators. Wireless communication devices with preferred beams orthogonal to each other are paired. A wireless communication device pair is selected. Data streams for the selected wireless communication device pair are scheduled in the same transmission time interval using an orthogonal variable spreading factor code.
