Power Control of Full-Duplex D2D Communication Underlying Cellular Networks

摘要

Full-duplex device-to-device communication (D2D) communications underlying cellular networks can share the resources of cellular users and thereby can improve spectrum efficiency and overall system throughput. This paper presents a low-complex power control algorithm to solve the problem that a pair of full-duplex D2D users reuse the uplink channel resources of a single cellular user, and full-duplex D2D users interfere with the cellular user. The algorithm maximizes the throughput while ensuring the quality of service (QoS) of the D2D users and cellular user. The simulation results show that the algorithm can improve the throughput and the throughput depends on the QoS requirements and the self-interference cancelation ability.
