Femto cells, also called home base stations, are small cellular access points installed by home users to get better indoor voice and data coverage with lower network operation cost. In this paper, the deployments of femto cells within LTE cellular networks are investigated. Based on the current partial co-channel deployment configuration for LTE Home evolved NodeB, a novel scheme of femtocell-aware spectrum arrangement is proposed for co-channel interference avoidance between macro and femto cells. The performance improvement of the proposed scheme has been validated by simulation results.
