New scheduling algorithm for Uplink LTE system

Abstract : In the LTE (Long Term Evolution) System, packet scheduling is considered the most important step of RRM (Radio Resource Management) to have better resource utilization. In this context, we proposed a new Uplink scheduling scheme for LTE networks and compared its performances with other well known algorithms such as the RME (Recursive Maximum Expansion), the RR (Round Robin) and the BCQI (Best-CQI) Uplink scheduler's algorithms. The RR scheduler is characterized by a high fairness, but low data rates at cell level. On the other hand, the RME scheduler is characterized by its low complexity, but poor fairness. Also, the BCQI scheme is characterized by high data rates, but poor fairness. The main goal of our proposed scheme was to use the Tabu method for to schedule and optimize the allocation of a PRBs (Physical Resource Blocks) efficiently between different users. Simulation results show that the newly proposed scheduling algorithm allows a fair distribution of available LTE resources while keeping an high system's throughput.
