Abstract

Device to device communication (D2D) and internet of things are anticipated to rule the globe in the upcoming days. The ever increasing demand for data traffic and throughput pose a unique venture in fifth generation (5G) industry, including limited spectrum and mass device connectivity. The proposed system signifies the specifications putforth by third generation partnership project for D2D communication underlying cellular network. It is highly focused on design and development of its physical layer and link layer . This hybrid 5G non-standalone system is adaptive to operate in different frequency bands. Since the users of D2D and new radio g-NodeB apportion same spectrum, interference would be the resultant. To quell such interference effects and also to maintain high capacity and throughput, here two mechanisms, namely spectrum aggregation and scheduling are emphasized. More over scheduling on component carriers are implemented successfully. At the end, the experimental outcomes prove that the aforementioned two methods results in rapid data transfer rate and eminent capacity with 0.5 ms latency in the controlled path loss environment.
