Abstract

Scheduling Algorithm is a key Radio Resource Management (RRM) mechanism to achieve Quality of Service (QoS) requirements and to optimize system performance of Long Term Evolution (LTE) network.. The LTE standard does not specify a scheduling algorithm and some schedules have been proposed in the literature. Most of them consider the channel state or some QoS metric, however, they do not consider the PF characteristics and the delay required by the user. Then, an enhanced scheduling algorithm was proposed based on LatencyRate (LR) server theory and system characteristics specified by the LTE standard. Properties of this proposal have been investigated theoretically and through simulations. A simulation is presented with video traffic and also performance comparisons with Proportional Fairness (PF) and Modified Largest Weighted Delay First (MLWDF) schedulers. The results show that the proposed schedule has a better performance compared with the above schedulers 2. Related Work
