Abstract :
Femtocells are low-power base stations which improve signal coverage in indoor environment. In order to deploy femtocells in macro cells, one of the essential issues is to evaluate the interferences towards the mobile users served by the macro cells. In this paper we mainly analyze the system performance of TD-SCDMA cellular radio network for HSDPA data services when operating femtocells. The fixed transmitting power scheme and the adaptive power control mechanism for femtocells are compared. A time-driven dynamic system level simulation is used to demonstrate the interferences of femtocells and the capacity performance of the macro cells.
