Abstract

Femtocells are one of the key enabling technologies for indoor
coverage extension and system capacity enhancement in Long
Term Evolution (LTE) cellular system. Cross-tier interference
between femtocells and macrocells is a great challenge. In
this paper, a resource allocation scheme is proposed to
minimize the interference and enhance the LTE femtocell
throughput. The fraction frequency reuse (FFR) scheme is
considered for LTE cellular system. The proposed scheme is
based on using small number of resource blocks (RBs) which
efficiently selected according to their signal to interference
plus noise ratio (SINR). Simulation results demonstrate that
the proposed scheme increases the femtocell throughput
using small number of allocated resource blocks (RBs) and
increases SINR of femtocells users. Also, the proposed
scheme significantly outperforms the conventional random
allocation scheme in terms of the achieved throughput and
SINR values when the number of allocated RBs is only 20% of
the total number of the available RBs.
