Outage Analysis of mmWave Integrated Device-to-Device Communication System under Nakagami Fading Channel

Abstract

Millimeter-wave (mmWave) communication has emerged as a promising candidate to meet the capacity demand in highly dense indoor environments for the next-generation cellular networks. Utilization of directional mmWave for Device to Device (D2D) communication systems provides low powered, high data rate transmission with manageable interference. In this paper, the rate and outage probability for mmWave integrated D2D communication system under Nakagami-m fading channel are derived. The performance of the model is analyzed by obtaining the closed-form expressions for the outage probability of a D2D user, wherein multiple cellular or D2D users are interfering with a mmWave integrated D2D transmission. The impact of various system parameters such as sectored beamforming gain probabilities and distance from interfering nodes on D2D outage probability are also investigated. Results show that the D2D outage probability decreases with an increase in main lobe gain, whereas increases with an increase in side lobe gain.
