Abstract

Long Term Evolution (LTE) has developed a new
technology in order to enhance indoor coverage. This new
technology is called femtocells and is achieved with the use of
access points installed by home users. However, interference
problem between the femtocell and the macrocell decreases the
system's capacity and as a result users' throughput. In this paper
we study the interference mitigation techniques in
femtocell/macrocell networks and we propose a frequency reuse
mechanism that leads to increased overall system performance.
In particular, the mechanism aims to maximize throughput via a
variety of combinations between inner cell radius and frequency
allocation to the macrocell. Additionally, a position minded
frequency allocation to the femtocells targets to further optimize
the total throughput of the cell.
