The delivery of multicast channels over capacity limited radio links requires efficient utilization of the air interface that make best use of the resources. One of the key radio resource management mechanisms in LTE mobile networks is the packet scheduler, which coordinates the access to shared channel resources. The decision of scheduling strategy plays a key role in guaranteeing good end to end LTE system performance and user quality of experience. Many packet scheduling schemes for mobile access networks have been proposed and implemented. In the paper, the consequence of the choice of downlink scheduling scheme in video streaming service quality is investigated through LTE system level simulations. We examine several scheduling systems and analyze the sophisticated scheduling method which provides the best video quality.
