Abstract: Femtocell is considered to be one of emerging technologies in next generation communication systems. It provides an effective method for us to solve the indoor coverage problem. However, deploying the femtocell system in the existing macrocell network still faces many problems, such as spectrum allocation between cells to maximize spectral efficiency to minimize cell interference, switching between cells and power control. In this paper, according to the frequency reuse method we use the soft frequency reuse (SFR) method to our two-tier femtocell network. Allocating different power to the internal area and external area of macrocell, we propose an improved femtocell spectrum allocation method. Simulation results and analysis showed that the proposed spectrum allocation algorithm can raise the performance of the macro users and increase the system capacity.
