MARIOS KOUNTOURIS ([email protected]) received his Dipl.-Ing. in ECE from the National Technical University of Athens, Greece, in 2002, and M.Sc. and Ph.D. degrees in electrical engineering from Ecole Nationale Supérieure des Télécommunications (Telecom ParisTech), France, in 2004 and 2008, respectively. His doctoral research was carried out at Eurecom Institute, France, funded by FT — Orange Labs, France. From February 2008 to May 2009, he was with the Department of ECE at the University of Texas at Austin as a postdoctoral research associate, working on wireless ad hoc networks under DARPA’s ITMANET program. Since June 2009 he has been with the Department of Telecommunications at SUPELEC (Ecole Supérieure d’Electricité), France, where he is currently an assistant professor. He also received the Best Paper Award at IEEE GLOBECOM 2009. He is a Professional Engineer of the Technical Chamber of Greece.

N2 - 3GPP LTE-Advanced has recently been investigating heterogeneous network (HetNet) deployments as a cost effective way to deal with the unrelenting traffic demand. HetNets consist of a mix of macrocells, remote radio heads, and low-power nodes such as picocells, femtocells, and relays. Leveraging network topology, increasing the proximity between the access network and the end users, has the potential to provide the next significant performance leap in wireless networks, improving spatial spectrum reuse and enhancing indoor coverage. Nevertheless, deployment of a large number of small cells overlaying the macrocells is not without new technical challenges. In this article, we present the concept of heterogeneous networks and also describe the major technical challenges associated with such network architecture. We focus in particular on the standardization activities within the 3GPP related to enhanced intercell interference coordination.
