In this paper, we analyse the outage probability of Device-to-Device (D2D) communications in a multi-cell frequency reuse-1 (FRF-1) system. We derive a formula for outage probability of a D2D link in the FRF-1 system when uplink resource sharing between cellular users and D2D users is enabled in the network. Based on this analysis, we propose a location-based power control mechanism for D2D which can enhance the outage performance of the D2D link, and at the same time, reduce the transmit power required for communication.

This paper presents a system-level simulation approach developed at the Poznan University of Technology for the evaluation of selected aspects of next generation wireless systems. The details of the considered environment and propagation models are given, as well as several important aspects of the simulator implementation methodology. Selected use cases of the presented simulation platform are demonstrated in relation to different research topics in the area of next generation wireless systems. The achieved simulation results show that the problems related to the development of modern wireless systems require detailed and precise modeling of the environment in order to accurately validate system performance. Keywords-system-level simulations, 5G, interference, D2D, relayingI.
