The intention of coalescing 5G and cognitive radio is to combine the information from wireless networks, portray and grow new technologies, networks and systems that assimilate into a flexible and dynamically-operating architecture. This paper is paying attention on the specifications of future generations and latest technologies which will be used in upcoming wireless mobile communication networks. This combination of technologies has been used to coerce the better integration, adaptation, modularity and standardization. Specially, the cross layer approach is used to surpass more information across layers. Radio access technology procedures enable higher peak data rates for end users as well as higher capacity and wider coverage.
