Abstract

A new dedicated resource allocation method for D2D communications in cellular systems employing fractional frequency reuse (FFR) is proposed in this paper. This method consists of three steps. For the first step, the permitted frequency resource set of each D2D link is determined. For the second step, a frequency resource assignment algorithm is proposed which takes both interference and load into considerations. For the third step, a slot resource scheduling algorithm is proposed which relies on the maximum weight independent set algorithm in the graph theory. Simulation results show the efficiency of the proposed method.
