| 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. | ||||
