Scheduling techniques evaluation in LTE systems with mixed data traffic

摘要

In this paper we implement and evaluate two scheduling techniques for mixed data traffic (VoIP and Video Streaming-VS) in LTE systems. We present results regarding resources allocation and traffic evaluation (mean throughput per user) for the Best CQI scheduler and compare to those for a Round Robin (RR) scheduler. Both services are delay-critical services but by prioritizing VoIP in the Best CQI scheduler, we achieve VoIP performance comparable to that in pure VoIP system. For VS users the remaining capacity is granted according to CQI. Comparing the schedulers results the required QoS (throughput per user) is reached for a greater number of VS users with the Best CQI scheduler.
