Power control and bandwidth allocation based on multi-service for uplink in LWA system

The LTE and WLAN Aggregation (LWA) system introduces the unlicensed band to solve the problem of explosive growth of multi-service in wireless cellular network systems. Users usually have different kinds of service requirements. In this paper, we propose the multi-service uplink resource distribution transmission (MDT) based on the service segmentation and heterogeneous wireless network. MDT divides the services of different Quality of Service (QoS) transfered by different links in the same frame. We combine the optimization of bandwidth allocation and the power control. Parallel scheduling based on multiple constraints is to obtain the maximum utilization efficiency while meeting the different requirements. The simulation results verify the convergence of the MDT, and the MDT satisfies the requirements of different service of the User Equipments (UEs).
