A system and method for multi-stage zero forcing beamforming in a wireless communications system is provided. A method includes receiving feedback information from each mobile station (MS) in a first plurality of mobile stations (MSs), selecting a first MS from the first plurality of MSs, and broadcasting information related to the first MS to the first plurality of MSs. The first MS having a largest value of a first metric based on the feedback information received from the first plurality of MSs. The method also includes receiving feedback information from each MS in a second plurality of MSs, selecting a second MS from the second plurality of MSs, and creating a precoding matrix from feedback information from the first MS and the second MS. The second MS having a largest value of a second metric based on the feedback information received from the second plurality of MSs.
