N2 - In ultra-dense network (UDN), the dense deployment of small cells can effectively improve the network throughput. In order to analyze the performance of UDN system, we propose a system-level UDN simulation framework in this paper, including system architecture, channel model and site model. Unlike previous works, we give a complete simulation flow. The path loss model shows that Line-of-Sight (LOS) propagation probability is bigger than LTE. A modified Poisson point process (PPP) model is proposed to simulate a dynamic base-station deployment process which approximates the realistic scenario. In addition, considering the utilization rate of small cells (SCs) and the proportion of SCs users, we analyze the density of SCs with different association strategies. Based on the proposed framework, simulation results show that if the density of SCs is less than a threshold, we can obtain a linear gain of system throughput while keeping the average throughput increasing.
