Abstract :
In this paper a multicast concept for Device-to-Device (D2D) communication underlaying a cellular infrastructure has been investigated. To improve system throughput and increase resource utilization, a novel interference coordination scheme is proposed. The proposed scheme includes two steps. First, in order to mitigate the interference from D2D transmission to cellular communication, we propose an efficient power control scheme to obtain an upper bound of D2D transmitter power. Next, based on the upper bound, two resource block (RB) allocation rules aiming to control the interference from cellular networks (CNs) to receivers in D2D multicast group are proposed. Simulation results show that by applying the proposed scheme, the performance of the hybrid system can be significantly improved compared to the conventional ways.
