“…In Figure 5(a) we show the sum rate Cumulative Distribution Function (CDF) of the D2D and cellular modes. As expected, see [6], the cellular mode has better performance than D2D mode when we consider a large number of position combinations. In this analysis, we find that the D2D mode outperforms the cellular mode in terms of sum rate in almost 30% of the cases.…”

“…Our aim is to investigate the influence of the uplink power control on D2D communication in three different situations. A more detailed study about the key distances in D2D communication can be found in [6]. The positions of the devices in a coordinate system centered at the BS1's position are given in the Table II.…”

“…In [6], we study the role of the main link distances as a factor that could influence the mode selection in a D2D communication system underlaying a cellular system. In addition to [6], this work focuses on the benefits of the D2D communication when jointly applied with a centralized power control algorithm in a multi-cell scenario. Furthermore, our analysis considers the feasibility of the power control problem given the target SINR values as part of the system performance evaluation.…”

New technologies have emerged to attend the increasing data rates demanded by multimedia services in wireless communication systems. In this context, Device-to-Device (D2D) communication appears as promising feature to improve data rates and increase spectral efficiency of wireless systems. Moreover, its combination with power control, which enables lowpower communication among devices and contributes to reduce interference, can enhance even more such benefits in future wireless systems. In this work, we investigate the leverage of the uplink power control on the D2D communication underlaying cellular networks. The results show that the D2D communication applied together with power control can overcome cellular mode performance in terms of sum rate.

The increasing demand for rich multimedia services and the scarcity of radio resources has motivated the research of technologies able to increase wireless systems' capacity without requiring additional spectrum. In this context, direct Device-to-Device (D2D) communication between User Equipments (UEs) is a promising technology. By allowing direct low-power communication among UEs, D2D communication leads to intelligent spatial reuse of radio resources, permits to offload the network and to increase its capacity and/or Quality of Service (QoS) levels. In this work, we provide a brief literature review on D2D communication, identify and discuss key issues related to the potential benefits of D2D communication within a cellular system, as well as present a distance-based study for defining scenarios in which D2D communication can increase the overall system capacity.

“…To understand the impact of user locations within the cell on the system performance, a distance-based study for specific scenarios in which D2D communications can increase the overall system capacity is addressed in [3], [4]. Results show that the use of D2D communications may provide considerable performance gains, but strongly depends on the distance among communicating and interfering devices.…”

Device-to-Device (D2D) communication, while being network-assisted, is seen as promising technology for the next generation of wireless systems as a mean to improve the utilization of cellular spectrum and to reduce the energy consumption of User Equipments (UEs). However, D2D communications can generate significant interference to the cellular network when the same Physical Resource Blocks (PRBs) are shared by both systems. The design of an efficient D2D network underlaying the cellular network with minimal impact on cellular communications is the key problem. In this paper, we provide an impact assessment of D2D communications on the performance of cellular communications in a Long Term Evolution (LTE)-like multi-cell scenario through system-level simulations. Simulation results show that the overall system capacity is always improved when D2D communications are enabled. However, the performance loss of cellular communications in Downlink (DL) is highly significant. For Uplink (UL), the impact on cellular performance is less noticed, being almost negligible for the urban-macrocell environment and acceptable for the spatial multiplexing-based multi-antenna configuration scheme.
