In this paper, we introduce two innovative concepts which have not been present in cellular systems for IMT-Advanced so far: Device-to-device (D2D) communication and network coding. Both of them are promising techniques to increase the efficiency of
Wireless cellular networks feature two emerging technological trends. The first is the direct Device-to-Device (D2D) communications, which enables direct links between the wireless devices that reutilize the cellular spectrum and radio interface. Th
