To provide high date rate for indoor services and communication, femtocells and microcells are planned in LTE- Advance system but main problem is how to reduce the interference between micro and femto cells and in the middle of the femtocells. In this paper we proposed regional Average channel state (RACS) to estimate the influence of interference and then we proposed hybrid clustering based on interference graph (HCIG) to reduce interference between femtocells and microcells. Based on the Results our scheme is given to reduce the interference and improve the spectrum efficiency.
