This work presents a novel approach for the avoidance of cross-tier interference in two-tier
networks comprised of Orthogonal Frequency Division Multiple Access (OFDMA) macrocells …

There are two main access policies (open and closed) to Femtocell Access Points (FAPs),
being closed access the customers favorite. However, closed access is the root cause of …

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

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 …

The two-tier femtocell network is comprised of a central macrocell underlaid with shorter
range femtocell hotspots. Due to the universal frequency reuse, this kind of new system …

In this paper, we address the problem of subchannel, rate and power allocation in OFDM-
based two-tier femtocell networks, which comprise a conventional macrocell and multiple …

This paper explores the trade-offs of different levels of access control in a mixed femtocell-
macrocell deployment with focus on reverse link (uplink) outage analysis. The aim is to …

In this paper, we draw our attention to the problem of interference avoidance in a macrocell-
femtocell network. Further, macro user equipments operate in a Frequency Division …

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

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 …
