Distributed Enhanced Inter-Cell Interference Coordination (eICIC) in LTE-Advanced HetNets: A Potential Game Approach
02 July 2015
In this paper we propose a distributed algorithm for jointly optimizing almost blank subframe (ABS) and cell selection bias (CSB) patterns in LTE-Advanced (LTE-A) heterogeneous networks (HetNets). We formulate the optimization problem as an exact potential game, where a Nash equilibrium point is guaranteed to be achieved within a finite number of plays. Through simulations, we are able to demonstrate the fast convergence of the algorithm, a 50% increase in average user throughput, and a significant improvement on the service fairness to the users. Results have shown its effectiveness in enhancing inter-cell interference management and network optimization.
