Spectral and Energy Efficiency Analysis of mmWave Communications with Channel Inversion in Outband D2D Network

Résumé

Device-to-Device (D2D) communications is a promising approach for wireless communicationsin terms of energy and spectrum efficiency. However, such communications increase interferences in acellular network. In this paper, we propose to lower these interferences by using millimeter wave directionalantennas. To analyze the impact of these techniques, we introduce mathematical sectored antenna modelsthat are deduced from mmWave antenna radiation patterns. Moreover, recent studies consider a constanttransmit power for the devices. Nevertheless, modern communications use power control techniques tomitigate energy consumption and interferences. The main contribution of our work is the consideration ofchannel inversion, which is more realistic than the commonly used transmit model.Most works dealing with conventional D2D communications propose to use stochastic geometry to modela D2D-enabled network in order to evaluate the impact of interferences and noise on the various links.The objective of this work is to analyze the SINR and the energy efficiency of Outband D2D links forUEs equipped with directional mmWave antennas. To do so, we implement an energy efficiency calculationthat considers both directional antennas and channel inversion. We propose to highlight the advantagesand drawbacks of directional mmWave antennas in Outband D2D for diverse antenna designs and differentenvironments.
