Previous generations of mobile telecommunications technologies (1G to 4G) addressed the demand for mobile voice and broadband data; 5G enables new services, ecosystems, and revenues on top of the existing ones, while also delivering improved end-user experience for existing scenarios. This chapter focuses on the main concepts, which are necessary to understand the role of Non-Terrestrial Networks in 5G. The 5G system architecture as specified by 3rd Generation Partnership Project (3GPP) is composed of logical nodes. Standardization makes it possible to specify the best possible technical solution given all the requirements of interested parties (especially operators, network infrastructure vendors, and chipset makers). The 3GPP provides the Reports and Specifications that define 3GPP technologies. 3GPP specifications and studies are contribution-driven, by member companies, in Working Groups and at the Technical Specification Group (TSG) level. The three TSGs in 3GPP are: Radio Access Networks, Services and Systems Aspects, and Core Network and Terminals.
