Abstract
Femtocells are one of the key enabling technologies for indoor coverage extension with system capacity and signal to interference plus noise ratio (SINR) enhancement in Long Term Evolution (LTE) cellular system. However, co-channel interference (CCI) is a critical issue that may significantly decrease the performance of femtocell and macrocells. So, the resource management techniques become the ideal solution that is desirable for interference management between macrocell and femtocells. Our proposed schemes aim to allocate resources between macrocell and femtocells to enhance the femto cell throughput and consequently the total cell throughput, manage the interference between macrocell and femtocells and satisfy the quality of service (QOS) requirement for macrocell and femtocell users. The first proposed scheme investigates the optimal cell design parameter such as, inner cell radius and power ratio between outer and inner regions of macro cell that maximize the total cell throughput, minimize interference and obtain a good degree of fairness between users. The second proposed allocation scheme is based on reducing the cross-tier interference by allocating the best group of the available resource blocks (RBs) that achieve minimum interference level for femtocell users. The soft frequency reuse and fraction frequency reuse schemes are considered for long term evolution cellular system due to their abilities to decrease the inter-cell interference and enhance the throughput for macrocells. The Simulation results demonstrate the ability of the two proposed schemes to enhance the femtocell throughput and consequently the total cell throughput, minimizing the cross-tier interference, enhance SINR for femo users and provide a good degree of fairness between users.
