Abstract-The fastest growing of multimedia services over future wireless communication system demand more network resources, efficient delivery of multimedia service with high users satisfaction, and power optimization of User Equipments (UEs). The resources and power optimization are significant in future mobile computing systems, because emerging multimedia services consume more resources and power. The 4G standard of LTE-A wireless system has adopted the Discontinuous Reception (DRX) method to extend and optimize the UE battery life, while there is no standard scheduling method to distribute the radio resources among the UE. This paper presents a downlink scheduler, i.e. Quality of Experience (QoE) Power Efficient Method (QEPEM) for LTE-A, which efficiently allocates the radio resources and optimizes the use of UE power using the DRX mechanism. We investigates how the different duration of DRX Light and Deep Sleep cycle influences the QoS and QoE of end users, using VoIP over the LTE-A. The QEPEM is evaluated with the traditional methods, in terms of System Throughput, Fairness Index, Packet Loss Rate, and Packet Delay. The QEPEM measures the user's QoE, and feedback to eNodeB for scheduling decisions along with other important parameters. Our proposed method reduces the packet delay, packet loss, and increases the fairness and UE's power saving with high users satisfaction.
