Enhanced intercell interference coordination challenges in heterogeneous networks
TL;DR: In this article, the authors present the concept of heterogeneous networks and also describe the major technical challenges associated with such network architecture, focusing in particular on the standardization activities within the 3GPP related to enhanced intercell interference coordination.
Journal ArticleDOI
OFDMA femtocells: A roadmap on interference avoidance
TL;DR: In this article a coverage and interference analysis based on a realistic OFDMA macro/femtocell scenario is provided, as well as some guidelines on how the spectrum allocation and interference mitigation problems can be approached in these networks.
