This paper studies a device-to-device (D2D) LAN underlaying a cellular uplink, where multiple D2D users (DUs) intend to communicate with a D2D receiver. Two interference alignment (IA) based D2D communication schemes are proposed to manage the interference between two networks. The first scheme is referred to as “interference-free” IA scheme. In this scheme, the interference signals from DUs are designed...
Device-to-Device communication enables high-speed services in the traditional cellular networks but brings potentially mutual interference. In this paper, the heterogeneous network of D2D and IMT-Advanced in a single cell is considered, where the D2D communication is assumed to share the uplink resource with cellular user. The definition of mode selection is first introduced and then a novel distance-dependent...
