In this work, the coexistence of femtocells and D2D communication with macrocells is analyzed. Heterogeneous networks (HetNets) are promising in the aspect of covering the demand of high data rates in cellular networks. Interference management issues in HetNets is an important issue which should be solved. One of the efficient interference management techniques is fractional frequency reuse (FFR). The key idea of this scheme is partitioning the whole frequency band into several non–overlapping parts and allocating them to the macrocell, femtocells and D2D communications in each region. We propose effective FFR schemes and resource allocation methods for macrocell, femtocells and D2D communications. Simulation results show that, the proposed structures can successfully mitigate the cross–tier interferences between macrocell, femtocell and D2D communication which results in significant increase in the system when compared to the random resource allocation.<\div>

This paper presents an efficient fractional frequency reuse (FFR) scheme for heterogeneous networks (HetNets) with D2D communication. Six directional antennas are used to cover the outer region of macrocell network and according to the location of the users, efficient resources are allocated to them. The goal of this work is to mitigate cross–tier interference between macrocell, femtocell and D2D communication as much as possible without worsening the spectral efficiency. According to the introduced scheme, each tier and D2D communication use whole spectrum simultaneously, but in each region, the resources are orthogonal to each other. The results demonstrate that the proposed resource allocation FFR scheme achieves higher throughput for macrocell, femtocell, and D2D when compared to the random resource allocation.<\div>
