摘要

Device-to-device (D2D) communications underlying cellular networks, results in the cellular interference to D2D user equipment (DUE)which is larger than the D2D interference to cellular user equipment (CUE). A joint resource allocation scheme is presented to both perform user equipment pairing and power allocation to minimise total interference of DUE and CUE. The scheme is composed of two parts: in the first one the base station assigns power to each CUE and each D2D transmitter by graphic method, and in the second one it selects the optimal CUE to pair with D2D pair by modified Hungarian algorithm in order to minimise total interference. The simulation results show that the proposed scheme can not only decrease the interference caused by D2D pair and that caused by CUE, but also increase the number of permitted D2D connections.
