In this paper we present rst real-time outdoor multi-user multi-antenna measurements based on system parameters close to 3GPP-Long Term Evolution. We demonstrate switching between various transmission modes in the downlink steered by a quantized feedback channel. Real time results show that an OFDMA proportional fair scheduler based on the quantized feedback achieves signi cant performance gains over a xed OFDM-TDMA system. However, the proportional fair scheduler results in user starvation periods in the event of correlated feedbacks. To this end, we formulate a downlink scheduling problem with zero-starvation as a short term fairness [5] objective. This is an integer programming (IP) problem. In this paper, we present a simple heuristic algorithm for this problem for K=2 users. Signi cant system sum rate gains are shown while still ful lling the fairness objective.
