Abstract

With the development of the 5G communication systems, mobile data traffic demand and users are greatly increased. Since D2D technology has been one of the widely used technology of 5G communication systems, the frequency reuse methods should be used to solve the shortage of the frequency channels of the D2D communication systems. Fractional Frequency Reuse(FFR) is a promising scheme to improve the utilization of the frequency spectrum. However, the capacity of different reuse method used in cell center and cell edge are totally different. This paper is trying to find out which frequency method used in cell edges and cell centers when considering the path loss of the communication and the shadow. And in this paper, different number of users and different percentage of the D2D pairs are also considered. The results show that the IFR1+txITL FFR method is the best one and number of users of the system doesn’t influence the capacity of the system a lot but the percentage of the D2D pairs really influence the capacity of the system.
