Comparison of Different Scheduling Algorithm for LTE

In this paper we evaluate the performance of Packet Scheduling (PS) for different packet scheduling algorithms of 3GPP UTRAN Long Term Evolution (LTE) Downlink. Packet scheduling is importance in 3G LTE, because different types of traffic with different Quality of Service requirements are competing of the resources. In this paper, packet scheduler for LTE downlink is described. Comparison of three basic packet scheduling algorithm with their simulation result with different amount of fairness is explained. This paper shows that by dividing the packet scheduler into a time domain, frequency domain and also utilizing those using different algorithms, the throughput fairness between users can be effectively controlled. Keywords—LTE, round robin, proportional fair, best CQI, scheduling.
