This paper describes the performance evaluation of a state-of-the-art adaptive control cell range expansion (CRE) technique in Heterogeneous Network (HetNet) with enhanced inter-cell interference coordination (eICIC) scheme. The features of the proposed adaptive control CRE technique are described through comparison with those of conventional methods. System-level computer simulation results such as average and 5-percentile user throughput are provided under the conditions of HetNet with eICIC, as parameters of almost blank subframe (ABS) ratio for eICIC. We confirmed that the proposed adaptive control CRE can improve 5-percentile user throughput while maintaining the average user throughput even for HetNet with eICIC.
