PERFORMANCE EVALUATION OF NOVEL SCHEDULING ALGORITHM FOR MIMO TRANSMISSION IN DOWNLINK 3GPP LTE CELLULAR NETWORK

摘要

In this paper we present and discuss the comportment of proposed novel scheduling algorithm for multiuser Multiple Input Multiple Output (MU-MIMO) transmission in downlink Long Term Evolution (LTE) system. The challenge of multiuser scheduling in the downlink Long Term Evolution system impose to guaranteed the high quality of service in addition to maximize the system capacity with high fairness index. The proposed scheduler, presented in this paper, exploit better the received Channel Quality Indicator (CQI) from the User Equipment (UE) in order to improve the system throughput and fairness index as compare with basic Round Robin and Proportional Fairness scheduler. The simulations results shows that the proposed scheduler outperform RR and PF algorithms for both fairness index and overall system throughput.
