Spectrum seems to be the lifeblood of wireless communication, which is of high demand as the traffic doubles every year. This increasing demand drives towards 5G NR, which is expected to support 100 folds increase in mobile devices, gigabit user data rate, ultra-low latency, high traffic and ultra-reliability. Since most of the available spectrum has been saturated, new methods that make use of spectrum in efficient manner must be considered. Through flexible 5G NR framework, 5G is aimed to utilize shared/unlicensed spectrum. Cognitive radio is the key enabler for operating through shared/unlicensed spectrum. In this situation, network interference caused by secondary users (SU) in accessing the unlicensed band for cognitive radio can be overcome by implementation of efficient resource management techniques. The interference issue among SU can be minimized to a large extent by efficiently allocating the available spectrum. Fuzzy Analytic hierarchy process (FAHP) seems to be an appropriate solution for spectrum allocation among SU without creating interference among themselves. The mathematical model proves that FAHP allocated the spectrum to the best SU.

Device-to-device (D2D) communication, which offers ultra-low latency for user communication, is projected to play a large role in future cellular networks. This new mode could work in either licensed or unlicensed spectrum. It's a fresh take on the classic cellular communication model. Its advantages, however, come with a slew of technological and financial difficulties that must be addressed before it can be fully integrated into the cellular ecosystem. This paper discusses the main characteristics of D2D communication and how we can use this to build Human Safety Device.
