Adaptive control CRE technique for eICIC in HetNet

This paper describes the performance of a state-of-the-art cell range expansion (CRE) technique: an adaptive control CRE for enhanced inter-cell interference coordination (eICIC) in Heterogeneous Network (HetNet). The features of the proposed adaptive control CRE technique are described through comparison with those of conventional methods. With eICIC in a HetNet, system-level computer simulation results such as average user throughput and 5-percentile user throughput are provided as parameters of almost blank subframes ratio for eICIC. This approach provides a remarkably effective solution for eICIC in a HetNet.
