Improving Device-to-Device Communication in Hybrid Microwave and Millimeter Wave Cellular Networks using Fractional Frequency Reuse Technique

Abstract

Device-to-Device (D2D) communication is one of the most promising technologies to enhance user experience in 5G and beyond. The concept of enabling D2D in cellular network has encounters some challenges, despite the huge benefit anticipated. However, resolving these challenges promises improved service delivery, spectrum efficiency and reduced latency amongst other gains.  Attempts to enable D2D in both microwave and millimeter wave network gained some traction in recent years in a bid to enable wider coverage and utilization of the technology. Some of the research attempts, challenges and prosects are discussed in this paper.
