Backhaul-Aware Scheduling for LWA with Energy-Throughput Tradeoff for an In-Order Packet Arrivals

In this paper, we propose a dynamic, energy-efficient traffic splitting and scheduling scheme for LTE-WLAN Aggregation (LWA) offloading system. The traffic splitting is based on full channel state information and, is formulated to achieve minimum transmission energy consumptions. Next, we present an efficient realization of a scheduling and packet offloading scheme that guarantees an in-order packet arrivals to their destinations. Finally, we propose an efficient approach to improve the energy efficiency of the transmission system by scaling the number of bits per symbol as long as the quality of service (QoS) of the applications can tolerate some additional delay. Simulation results have indicated the efficiency of the proposed models and their suitability for practical deployments.
