Support of femtocells is an integral part of the Long Term Evolution-Advanced (LTE-A)
system and a key enabler for its wide adoption in a broad scale. Femtocells are short-range …

This paper provides a holistic overview of multi-cell scheduling strategies in emerging
wireless systems. Towards this objective, the evolution of interference management …

In this paper we develop a tractable framework for SINR analysis in downlink
heterogeneous cellular networks (HCNs) with flexible cell association policies. The HCN is …

Cellular systems are becoming more heterogeneous with the introduction of low power
nodes including femtocells, relays, and distributed antennas. Unfortunately, the resulting …

This paper investigates price-based resource allocation strategies for two-tier femtocell
networks, in which a central macrocell is underlaid with distributed femtocells, all operating …

Nowadays energy crisis and global warming problems are hanging over everyone's head,
urging much research work on energy saving. In the ICT industry, which is becoming a major …

Future mobile networks are converging toward heterogeneous multitier networks, where
macro-, pico-, and femtocells are randomly deployed based on user demand. A popular …

Recently, operators have resorted to femtocell networks to enhance indoor coverage and
increase system capacity. Nevertheless, to successfully deploy such solution, efficient …

Femtocell networks, consisting of a conventional macro cellular deployment and overlaying
femtocells, forming a hierarchical cell structure, constitute an attractive solution to improving …

A fundamental choice in femtocell deployments is the set of users which are allowed to
access each femtocell. Closed access restricts the set to specifically registered users, while …
