摘要
Modern wireless networks promise high performance and quality of service to the ever-growing number of mobile users. However, limited radio resources, high interference and poor channel conditions are significant obstacles for reliable and high quality service provision. To tackle these issues, a scheme where JT-CoMP is deployed in a Cloud Radio Access Network (C-RAN) small cell topology is proposed, where the clustering of the remote radio heads (RRHs) is based on a dynamic coalition formation algorithm. To obtain more reliable and accurate results of the JT-CoMP deployment, TruNET wireless was used alongside Vienna LTE-A Downlink System Level Simulator to model the propagation environment. To test our proposed scheme’s performance, the throughput of immobile and high-speed moving users is examined in separate scenarios.
