Full duplex device-to-device communication in cellular networks

Abstract

In this paper we investigate the applicability of inband full-duplex (FD) radios in device-to-device communication (D2D) in cellular systems. The key challenge in FD radio design is the large self-interference on receiver. It is not possible to completely cancel the self-interference in FD radios. Considering the residual of self-interference, we study the performance of system while D2D link is operating in half-duplex and full-duplex mode. A cellular system is considered while D2D users are exploiting the same resources with cellular users in uplink. We apply a power control method for D2D pair to limit the interference from them on base station. For interference management from cellular transmissions on D2D receivers, interference limited area method is used. Simulation results show that using the most recent FD radios in D2D systems can almost double the throughput of the D2D link.
