The small cell technology for 4G, B4G and 5G wireless communications aims at enhancing indoor coverage, increasing
capacity, and offloading the overlay eNodeB traffic. However, the interference between small cell and eNodeB can
dramatically decrease the overall capacity of the network. A solution for such scenario is emergently necessary. In this paper,
we first give a multiple objective formulation for interference management. We then propose an interference coordination
mechanism based on Soft Frequency Reuse (SFR) for LTE heterogeneous network consisting of eNodeB and small cells.
Comparing with existing solutions, the proposed scheme has better system throughput, what is more, it also guarantees the
QoS and fairness of cell-edge mobile users.
