Abstract

Device-to-Device (D2D) communication provides high data rate requirements within the available access network and is viewed as a promising solution for the increasing mobile data traffic. D2D communication carries out direct communication for users located in close proximity to each other, without passing through the eNB. However, integration of D2D communication in cellular network introduces technical challenges like interference among cellular users and D2D pairs, and D2D pairs and eNB for the uplink cellular system which deteriorates the system performance. In this paper, we propose a distance-based throughput optimization method for D2D communications in a sectored multicell system using fractional frequency reuse (FFR) method. The simulation results show that our proposed scheme significantly improves system performance by mitigating interference.
