Performance evaluation for different types of small cells with optimized transmssion power

This paper presents user throughput performance for several different types of small cells with optimized transmission power. System level computer simulation results such as average user throughput and the cell edge user throughput performance are provided for several different types of small cells. We show how to decide the transmission power for a pico evolved Node B on the basis of a path loss scenario. Furthermore, the possibility of the increase of system capacity using small cells is also investigated in the simulation under conditions of increased user equipment density. This study will be effective for designing small cells in future mobile communication systems such as LTE-Advanced and beyond.
