To date, group-oriented communications have been mainly exploited for delivering multimedia services in human-oriented while, future fifth generation (5G) cellular networks, objects will be the main target. Internet of Things (IoT) undoubtedly play a key role 5G wherein massive machine-type (mMTC) feature use case as crucial challenging since IoT connections are predicted to grow heavily next f...

Device-to-device (D2D) communications underlaying a cellular infrastructure has recently been proposed as a means of increasing the resource utilization, improving the user throughput and extending the battery lifetime of user equipments. In this paper we propose a new distributed power control algorithm that iteratively determines the signal-to-noise-and-interference-ratio (SINR) targets in a ...

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 cellular communication systems, especially from a network point of view. First, we study the potential gains from D2D communication as an underlay ...
