Modeling Multi-mode D2D Communications in LTE
In this work we propose a roadmap towards the analytical understanding of Device-to-Device (D2D) communications in LTE-A networks. Various D2D solutions have been proposed, which include inband and outband D2D transmission modes, each of which exhibits different pros and cons in terms of complexity, interference, and spectral efficiency achieved. We go beyond traditional mode optimization and m...
متن کاملD2D Communications with Enhanced Physical Layer Security in Cellular Networks
In this paper, we consider secure device-to-device (D2D) direct communication in cellular networks for wiretap channel. We assume that D2D transmitter sends its data to desired D2D receiver by reusing frequency resources originally allocated to the cellular link transmission between a base station (BS) and a cellular user. When there is a single eavesdropper (ED) in wiretap channel, we propose ...
متن کاملGeneralized Analysis and Optimization of D2D Communications in Cellular Networks
This paper develops an innovative approach to the modeling and analysis of downlink cellular networks with deviceto-device (D2D) transmissions. The analytical embodiment of the signal-to-noise and-interference ratio (SINR) analysis in general fading channels is unified due to the H-transform theory, a taxonomy never considered before in stochastic geometry-based cellular network modeling and an...
متن کاملCognitive and Cache-enabled D2D Communications in Cellular Networks
Exploiting cognition to the cache-enabled deviceto-device (D2D) communication underlaying the multi-channel cellular network is the main focus of this paper. D2D pairs perform direct communications via sensing the available cellular channels, bypassing the base station (BS). Dynamic service is considered and the network performance is evaluated with the stochastic geometry. Node locations are f...
متن کاملPrecoder Design for Multicast D2D Communications Underlaying Cellular Networks
In this paper, we consider multicast device-to-device (D2D) direct communication underlaying cellular network where D2D multicast link reuses uplink frequency resources of cellular communication. We assume that a D2D multicast transmitter is equipped with multiple transmit antennas. Hence, well-known multiple antenna transmission schemes can be used in D2D multicast transmitter to reduce the in...
