In this paper, we present a Quality of Experience (QoE)-aware scheduler aiming at maximizing the minimum Mean Opinion Score (MOS) in a system subject to attaining at least a minimum number of satisfied users. Different of the benchmarking solution, the proposed one takes into account all the data that the User Equipments (UEs) have already received, and not only the data of a specific instant of time, thus suitably excluding UEs already satisfied. According to simulation results, the proposed solution not only improves the users’ satisfaction and the minimum experienced MOS in the system, but it also doubles the capacity in terms of supported number of users compared to benchmarking solution. It is also able to handle imperfections on the Channel State Information (CSI).
