An efficient scheduling algorithm plays an important role for effective utilization of radio resources, high data rate, low latency, fairness among users within a system as well as for the entire system performance. This paper evaluates the performance of three basic packet scheduling algorithms in downlink 3GPP LTE cellular network under universal frequency reuse scheme by executing a simulation in different channel conditions in terms of maximum throughput and fairness metrics.

This paper provides evaluation of the downlink (DL) transmission in LTE. The evaluation is performed for a regular hexagonal multi-cell deployment, universal frequency reuse scheme2x2 Multiple Input Multiple Output (MIMO) antenna configuration and varying packet scheduling algorithm. This study evaluates the advantages and benefits of combining several spectrum efficiency improvement techniques over multipath selective fading channel conditions and various bandwidth sizes (BW). The proposed paper compares MIMO improvements to Single Input Single Output (SISO) scenario in terms of cell and user throughputs. The evaluation is performed through a custom simulation package developed for this purpose..
