A Survey on the Progressing 5G(NR) Modern Technologies and their Challenges

Since it’s inception, next-generation 5G communication has been gaining huge attention from all corners. 5G communication system attempts to transcend all limitations of 4G and previous generation cellular systems and lends some exciting features. This paper presents an intricate survey of next-generation 5G systems and some of the vital emerging techniques along with their significance and challenges. We propose an architecture for fifth-generation cellular systems that incorporates many technologies like Massive Multiple Input Multiple Output (MEMO), Cognitive Radio, Millimetre-Wave technology (mm-Wave), Device to Device communication (D2D), Internet of things, and so on. In the later section, we highlight some future challenges for wireless communication which need a thorough analysis to meet the given requirements.
