To solve the interference and power consumption problems between the macrocell base stations (MBSs) and the femto-cell base stations (FBSs), and that among FBSs, the paper proposes a power-efficient clustering-based spectrum allocation strategy (CSAS). According to outage probability of femto-cell users (FUEs), the maximum number of femtocell base stations contained in a cluster is derived. Under the restriction of the cluster capacity and OP, SIR of FUEs and minimum interference distance between FBSs in a cluster is further derived to strictly guarantee each FUE's SINR. A clustering algorithm and a spectrum allocation algorithm are proposed. Simulation results show that the proposed strategy improves power efficiency of the network and spectral efficiency of the femto-cell network.
