The IMT-2020 framework includes feature performances for a more flexible and reliable system. The minimum technical requirements of IMT-2020 radio interface technologies are described in a report ITU-R M.2410 [23]. The report also provides the necessary background information concerning the individual requirements and the chosen operational values. The another report ITU-R M.2412 [24] prescribes methodology, test environments and configurations of channel models used for evaluation for radio interface requirements. Within the development of detailed specifications, the key minimum technical performances are used in specification and evaluation of the radio interface technologies. These requirements are planned to provide the objectives and to set a specific level of performance. The report presents the technical performance requirements for the radio interface and specifies their values (Table 7.1).
4G and 5G Systems
Published in Hossam Fattah, 5G LTE Narrowband Internet of Things (NB-IoT), 2018
5G is designed to support the ITU requirements for IMT-2020 capabilities [4] as shown in Figure 2.1. The peak data rate of IMT-2020 for enhanced mobile broadband is expected to reach 10 Gbps and can increase up to 20 Gbps. The spectrum efficiency is expected to be three times higher compared to IMT-Advanced. IMT-2020 is expected to support 10 Mbit/s/m2 area traffic capacity as the case in hot spots. IMT-2020 would be able to provide 1 ms over-the-air latency, capable of supporting services with very low latency requirements. IMT-2020 is also expected to enable high mobility up to 500 km/h with acceptable Quality of Service (QoS) for high speed trains. Finally, IMT-2020 is expected to support a connection density of up to 106 devices per km2, for example, in massive machine type communication scenarios.
4G/5G Radio Access Network
Published in Saad Z. Asif, 5G Mobile Communications Concepts and Technologies, 2018
The 5G NR is currently under the defining stage. According to ITU-R, IMT-2020 (including 5G) are mobile systems that include new radio interface(s) that support new capabilities of systems beyond IMT-2000 and IMT-Advanced [56,74]. The ITU-R has envisioned the following three usage scenarios for IMT-2020 [5,75] eMBB: providing higher speeds for applications such as web browsing, streaming, and video conferencing.URLLC: enables mission-critical applications, industrial automation, new medical applications, and autonomous driving that require very short network traversal times.mMTC: extends LTE IoT capabilities to support a huge number of devices with enhanced coverage and long battery life.

In order to use novel mobile communication technologies, they are standardized by telecommunications development organizations. Otherwise, it is not possible for providers to build systems that communicate with each other. This standardization takes place in two stages. First, an intergovernmental organization sets guidelines in the form of goals, KPIs and schedules. The ‘International Telecommunication Union’ (ITU) is the intergovernmental organization responsible for global telecommunications affairs, founded by the United Nations in 1865. It is responsible for issues involving telephone calls, satellites, and the internet . The ITU covers the general radio system aspects of international mobile telecommunications (IMT) systems, including 3G, 4G, 5G and future generations. It publishes requirements that telecommunications systems should meet in the future. These are, for example, IMT-2000 for 3G, IMT-advanced for 4G and currently IMT-2020 for 5G. It was agreed that if the requirements are met, then this standard can be called a new generation of mobile communications. A comparison of the requirements of IMT-advanced to IMT-2020 can be seen in Figure 8 on the left. Since the characteristics of a system with the requirements given in IMT-2020 can also be used increasingly for industrial purposes, the three areas – eMBB, mMTC and uRLLC – have been subdivided.

The 3rd Generation Partnership Project (3GPP), which is the standard body responsible for developing the technical specifications of 3G and 4G networks, has been working actively on the technical specifications of 5G which was submitted for International Mobile Telecommunications 2020 (IMT-2020) to International Telecommunication Union Radiocommunication Sector (ITU-R) where they were evaluated before they could be integrated into the 5G standards. ITU had set the following deadlines which had to be met by 3GPP for 5G standardization: Initial 5G technology- by the 32nd ITU-R WP5D meeting (June 2019)Detailed 5G specification- by the 36th ITU-R WP5D meeting (October 2020)
