Title: An effective interference alignment approach for device-to-device communication underlaying multi-cell interference network
Abstract: We consider the device-to-device (D2D) communication underlaying multi-cell interference system, in which the cellular downlink (DL) resource is reused by K cells and two D2D transmission links within each cell. In this paper, we propose an interference alignment (IA) scheme that can effectively reduce both the inter-cell interference and intra-cell interference. It has been demonstrated that a total of (K + 1)M degrees of freedom (DOF) can be achieved for K-cell interference system with underlaying D2D transmission, where M is the number of antennas at each base station, cellular UE (user equipment) and D2D UE.
