Testing of emerging IMT-2020 technologies

​(Questions 9/11, 10/11 and 11/11 were merged into new Question 16/11 on 18 January 2021, following endorsement by TSAG)​

Motivation
The recent trends (such as 5G/IMT-2020, IoT technologies) may lead to changing the architecture of the existing networks that will require higher network performance.

The 5G-based technologies are basically created for developing super-dense heterogeneous networks which can be used for establishing sessions/connections among various types of terminal equipment such as mobile phones/tablets, sensor nodes, vehicular ad hoc networks (VANET) terminals, the medicine terminals and so on. Furthermore, the mesh networking principles which aimed at establishing peer-to-peer connection, e.g. device to device (D2D) connection, between two and more terminal devices without using network infrastructure (e.g. base stations) may be considered as a kind of scenario used in such heterogeneous networks. The development of a testing methodology and test suites for technologies used on the super-dense heterogeneous networks such as 5G/IMT-2020 networks is important in terms of interoperability and interconnection.

In addition, these kind of networks should form a platform for new services as tactile Internet services which will be made available in the near future. The tactile Internet service requires an end to-end delay of not more than 1 ms (ultra-low latency) and therefore will demand the modification and decentralization of the current network architecture. The development of the methodology and test suites of tactile Internet services is considered an important issue for 5G/IMT 2020 networks.
