Considerations of small cell strategy in mobile communication systems

This paper presents a design method for a small cell system formed by splitting a macro cell from the perspective of user throughput performance. System level computer simulation results such as average user throughput and the cell edge user throughput performance are provided for several types of small cell. Furthermore, the possibility of the increase of system capacity using small cells is also investigated in the simulation under conditions of increased user equipment (UE) density. This strategy is important for realizing a small cell strategy for heterogeneous networks (HetNets) and relaying in future mobile communication systems such as LTE-advanced and beyond.
