Inter cell interference is one of the most serious problems in LTE-Advanced networks and beyond (5G). This issue is the direct result of two major features: the frequency reuse factor equal to one and the heterogeneous deployment of networks (HetNets). Many solutions have been proposed by the 3GPP project since its early Release 8 in order to mitigate interference. The most recent one is Coordinated...
Since their launching as voice only networks, mobile communication networks have witnessed a perpetual evolution. In the last years, the attention was addressed to high data rate networks. The lately 3GPP released LTE-Advanced network was the first to completely fulfill 4G requirements. However, performance gains remain limited due to severe interference levels. This paper is a survey upon the evolution...
