• Receive ZF beamform<strong>in</strong>g <strong>MIMO</strong> broadcast systems comb<strong>in</strong>ed<br />
with multiuser schedul<strong>in</strong>g<br />
• An alternative MU-<strong>MIMO</strong> technique to use feedback<br />
channel for a different purpose => user selection.<br />
• Has advantages <strong>in</strong> terms of robustness aga<strong>in</strong>st CSI<br />
and feedback l<strong>in</strong>k errors [Wang’10]<br />
