I. Introduction
5G specification is the fifth generation of mobile communication systems specified by The International Telecommunication Union (ITU). The purpose of 5G specification is to provide a standard set of technical specifications and requirements that enable the development and deployment of 5G networks and services [1]. The 3rd Generation Partnership Project (3GPP) acts as the organization which publishes several documents serving 5G specifications. These documents provide the specifications for 5G networks used by network operators, equipment manufacturers, and other stakeholders to ensure that their products and services are compatible with the 5G standards.
