Device-to-device (D2D) communications is identified as potential technology for future cellular networks. It is a promising concept to provide the high data rate requirements for bandwidth hungry applications like social networking, multimedia services etc. It facilitates better utilization of radio resources and shorter transmitter receiver delays and therefore better user performance. In this paper framework for studying performance of D2D communications in orthogonal frequency division multiple access based multicellular scenario is developed using downlink cellular resources. The load condition of D2D mode in addition to that of cellular mode plays an important role. The performance of both modes for their respective load conditions have been analyzed. The key parameters analysed are ratio of signal power to noise plus interference power (SINR), outage probabilty, effect of variation in D2D transmitter power, capacity, mode selection and D2D mode switching distance. The goal of the paper is to find the optimum distance for switching to D2D mode from cellular mode for loads with different power ratios. The results shows that D2D communications is beneficial for cellular edge UEs and improves their capacity. It is seen that with increase in load in both the cellular and D2D modes the corresponding link capacity falls. It is also seen that as the cellular load increases, the switching distance moves away from BS while it moves towards the BS when the D2D load increases.

“…In order to model the random number of users and random user positions, we use mathematical tools from stochastic geometry [34] which are powerful in analytically quantifying certain metrics in closed-form. Some work in the literature of D2D communications in single-antenna systems that exploits these tools can be found in [35][36][37][38][39][40]. There are certain studies in the context of MU-MIMO for single tier network in stochastic geometry considering equal or smaller than number of antennas and users like [41,42].…”

In this paper, we investigate the coexistence of two technologies that have been put forward for the fifth generation (5G) of cellular networks, namely, network-assisted device-to-device (D2D) communications and massive MIMO (multiple-input multiple-output). Potential benefits of both technologies are known individually, but the tradeoffs resulting from their coexistence have not been adequately addressed. To this end, we assume that D2D users reuse the downlink resources of cellular networks in an underlay fashion. In addition, multiple antennas at the BS are used in order to obtain precoding gains and simultaneously support multiple cellular users using multiuser or massive MIMO technique. Two metrics are considered, namely the average sum rate (ASR) and energy efficiency (EE). We derive tractable and directly computable expressions and study the tradeoffs between the ASR and EE as functions of the number of BS antennas, the number of cellular users and the density of D2D users within a given coverage area. Our results show that both the ASR and EE behave differently in scenarios with low and high density of D2D users, and that coexistence of underlay D2D communications and massive MIMO is mainly beneficial in low densities of D2D users.

Device-to-device (D2D) communication facilitates two users in close proximity to communicate directly, bypassing the Evolved Node B (eNB). It provides several advantages like increased spectral efficiency, energy efficiency, decreased transmission delay, and traffic offloading from eNBs. Native support of D2D communications in the emerging fifth generation cellular systems raises significant challenges, like interference, mode selection, resource allocation, and security. Ratification of standards and collaborative research works between industries and academia are now focusing to gradually resolve these challenges. In this paper, we present a novel survey of D2D communications. Our survey provides a new classification of major research works in D2D communications on the basis of frequency and control. Subsequently, major D2D architectures, protocols, and relevant applications are discussed. We also make a detailed review of the analysis techniques and point out open research challenges.
