A novel QoE-based carrier scheduling scheme in LTE-advanced networks with multi-service

Liu, Fei and Xiang, Wei and Zhang, Yueying and Zheng, Kan and Zhao, Hui (2012) A novel QoE-based carrier scheduling scheme in LTE-advanced networks with multi-service. In: 76th IEEE Vehicular Technology Conference (VCT 2012-Fall): Towards Sustainable Mobility, 3-6 Sep 2012, Quebec City, Canada.


Carrier aggregation is one of the key techniques for the advancement of long-term evolution (LTE- Advanced) networks. This article proposes a quality- of-experience (QoE)-based carrier scheduling scheme for networks with multiple services. The proposed scheme aims at maximizing the user QoE, which is determined by both the application-level and network-level quality of services. Packet delay, as an essential factor affecting QoE, is first discussed under the context of QoE optimization as well as the data rate. The component carriers are dynamically scheduled according to the network traffic load by the proposed novel scheme. Simulation results show that our approach can achieve significant improvement in QoE and fairness over conventional approaches.
