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 …

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 …

In order to suppress cross-tier interference (CTI) and inter-cell interference (ICI) between
adjacent macrocells, this paper proposes an effective resource allocation scheme for the two …

Femtocells that use co-channel allocation with macrocells can considerably increase
wireless coverage and system capacity, especially for indoor and cell-edge users. However …

We conceive an interference mitigation scheme, for twin-layer networks for protecting the
macrocell-users, from the interference imposed by the femtocells as well as for mitigating the …

We study a cognitive channel reuse approach for autonomous femtocell deployment in an
OFDMA-based cellular network. The objective is to manage the uplink interference from …

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

The cognitive femtocell has emerged as an exciting technology to solve the indoor coverage
problem in future cellular networks. Recently, several technical issues for the cognitive …

In this paper, we propose a base station selection and resource allocation model for OFDMA
macro-femtocell networks. Dense deployment of femtocells can cause severe interference …

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