Interference control and quality-of-service (QoS) awareness are the major challenges for
resource management in orthogonal frequency-division multiple access femtocell networks …

With the introduction of femtocells, cellular networks are moving from the conventional
centralized network architecture to a distributed one, where each network cell should make …

In order to improve the spectrum efficiency in the femtocell network and mitigate the co-
tier/cross-tier interference, we propose a novel graph-theoretic scheme based on coloring …

Femtocells have been considered as a promising technology to provide better indoor
coverage and spatial reuse gains. However, the co-channel deployment of macrocells and …

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

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

We consider the joint subchannel allocation and power control problem for orthogonal
frequency-division multiple-access (OFDMA) femtocell networks in this paper. Specifically …

Femtocell technology has gained widespread attention recently due to its advantages, such
as infrastructure cost reduction, improved service coverage and high data throughput in …

We consider the joint resource allocation and admission control problem for Orthogonal
Frequency-Division Multiple Access (OFDMA)-based femtocell networks. We assume that …

Open access is an efficient approach to reduce cross-tier interference in femtocell networks.
In this paper, we study resource allocation in open access OFDMA femtocell networks to …
