A Low-Complexity Distributed Inter-Cell Interference Coordination (ICIC) Scheme for Emerging Multi-Cell HetNets

Abstract

In this paper, we propose a low-complexity distributed Inter-Cell Interference Coordination (ICIC) for emerging multi-cell HetNets (Heterogeneous Networks). The proposed scheme is quickly solved using linear programming tools and aims to maximize both the critical and the overall performance of the multi-cell system. Additionally, a utility measure is used to provide a varying level of user fairness to satisfy the most demanding network providers. Simulation results confirm the low-complexity of the proposed algorithm and its increased effectiveness over a number of state-of-art interference avoidance schemes.
