    Heterogeneous Networks (HetNets) are introduced by the 3GPP as an emerging tech- nology to provide high network coverage and capacity. The HetNets are the combi- nation of multilayer networks such as macrocell, small cell (picocell and femtocell) networks. In such networks, users may suffer significant cross-layer interference. To manage the interference the 3GPP has introduced Enhanced Inter-Cell Interference Coordination (eICIC) techniques, Almost Blank SubFrame (ABSF) is one of the time- domain technique in the eICIC solutions. We propose a dynamically optimal ABSF framework to enhance the small cell user downlink performance while maintains the macro user downlink performance. We also study the mechanism to help the small cell base stations cooperate efficiently in order to reduce the mutual interference. Via simulation, our proposed scheme achieves a significant performance and outperforms the existing ABSF frameworks.
