Study of 5G services standardization: specifications and requirements

5G cellular system is expected to meet the market segments requirements, by introducing new use case and services beside the traditional services introduced by the current cellular systems. Various types of services and applications are expected to be delivered by the 5G systems with different requirements and deployment scenarios. The 3GPP defines these services and their market impacts in release 14 and 15. In this work, we review all 5G uses cases announced by the 3GPP release 14 and 15 for the 5G systems. The main categories of these use case are defined including their specifications and requirements. Furthermore, some main use cases are introduced including their deployment scenarios and potential services requirements. We conduct all features and requirements of these services from the 3GPP release 14 and 15.
