On the Performance of the Device-to-Device Communication with Uplink Power Control

Abstract

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 two aforementioned regions are defined as: Considering this, Figure 2 illustrates these two regions, where the dark areas represent the areas of interest for each region. It is worth mentioning that the above values chosen for R i and R o have been defined based on previously performed experimental observations [12], [13].…”
