Abstract

Abstract: As the effective methods to solve the load balance and interference control problem in heterogeneous cellular networks (HCN), cell range expansion (CRE) and enhanced inter-cell interference (eICIC) attract the attention of many researchers. However, most of the current works are under the assumption of uniform user distribution for simplicity, which is not applicable for the non-uniform user distribution scene. We intend to jointly optimize CRE and eICIC in HCN with non-uniform user distribution. Due to the complexity of the optimization problem, Stackelberg Game is used to model the optimization process of CRE and eICIC where macro base station (MBS) decides the eICIC strategy as leader and small cell base stations decide the respective CRE scheme as followers. Moreover, a solution algorithm is proposed to achieve the Stackelberg equilibrium (SE). The simulation results show the convergence of our proposed algorithm of SE and the effectiveness of our proposed solution.
