Abstract

Due to the rapid growth of mobile traffic, most of the mobile network operators (MNOs) recently consider the deployment of heterogeneous network (HetNet) including small- and personal-cell. Since small- and personal-cells in HetNet distribute the mobile traffic concentrated on a few macro-cells and reuse the frequency bandwidth allocated in macro-cell, they can alleviate the traffic load of macro-cell and enhance the system capacity in overall network. However, the drawback due to the cross- and co-tier interference between various cells decreases the gain obtained by the deployment of small- and personal-cell. In this paper, we develop a system-level simulator for HetNet based on LTE-Advanced (LTE-A) system in order to carefully analyze these effects of small- and personal-cell deployment before their release. For the purpose, we consider three HetNet scenarios, macro-cell only, macro- and small-cell, and macro- and personal-cell scenarios, and adopt the cell layout for each scenario, the realistic wireless channel models, and the real time graphic user interface (GUI) to the developed simulator. Through the performance evaluation by utilizing the developed simulator, we confirm that the overall performance in HetNet is affected by the characteristics of small- and personal-cell.
