A new user scheduling scheme in LTE/LTE-A networks using cross-layer design approach

This paper proposes a new cross-layer based packet scheduling scheme for multimedia traffic in Long Term Evolution (LTE)/LTE Advanced (LTE-A) network. The effective use of the limited resources still remains a major challenge in mobile networks across the globe. A dynamic user scheduling scheme is very important towards actualizing an effective utilization of the limited available resources in LTE/LTE-A networks without compromise to the Quality of Service (QoS) demands of varying users. Hence, the need for an effective user scheduling algorithm cannot be overemphasized. The aim of this paper is to propose a new scheduling scheme called Channel Aware Queue Aware (CAQA) Scheduler that will provide a good trade-off among QoS, fairness and throughput. The newly proposed scheduler is compared to existing ones through simulations, and various performance indices have been used for evaluation.
