| Abstract: | Multiple antennas are used here to enhance the scheduling task at a multi-antenna base station. After applying a zero forcing transmit beamforming, the scheduling shall distribute the resources among the users. Several criteria are presented and their performance in the high Signal to Noise Ratio (SNR) range is analyzed. The next issue is to take into account the SNR requirements from the users and perform the admission control accordingly. An algorithm that yields the optimum performance is proposed, together with a new criterion that falls between the optimization of the best global performance and the satisfaction of the individual needs. Simulation results are provided to show the performance of the techniques. | ||
