Performance Modeling and Evaluation of Novel Scheduling Algorithm for LTE Networks

Long Term Evolution (LTE) packet scheduling plays an essential role as part of LTE´s Radio Resource Management (RRM) to support successful implementation of new data services across the LTE network. The main contribution of this paper is to model and propose a novel scheduling scheme for LTE networks and to compare its performance with the performances of both the Best-CQI and RR Uplink schedulers. The Best-CQI scheduler is characterized by high data rates at cell level, but poor fairness. On the other hand, the round robin (RR) scheduler is characterized by low data rates at cell level, but good fairness. The main goal of our proposed scheme is to process these two conflicts terms in a better way. Performance modeling results presented in the paper show that the newly proposed scheduling scheme allows fair distribution of available LTE resources while at the same time keeps the system´s capacity utilization as good as possible.
