dc.description.abstractIn this paper we introduce a new Pre-Processing Method (PPM) and we observe its impact in scheduling algorithms. We also suggest a Cumulative Distribution Function (CDF) curve of Signal-to-Noise Ratio (SNR) of the scheduled users. This CDF curve reflects characteristics of application and information about scheduling policies. Based on these curves, thresholds are defined in order to avoid reporting of unnecessary Channel State Information (CSI). This saving of resources is very important when dealing with limited feedback that may limit the system performance/capacity. Simulation results confirm the potential of the proposal.pt_BR
