modelled and critical aspects in system design and performance can be investigated. Focus is thus on scenarios testing limits of performance. 8.1 Usage Scenarios As defined in Recommendation ITU-R M.2083, IMT-2020 is envisaged to expand and support diverse usage scenarios and applications that will continue beyond IMT-Advanced. There are three usage scenarios for IMT-2020 as follows: Enhanced Mobile Broadband (eMBB): This usage scenario will come with new – application areas and requirements in addition to existing Mobile Broadband applications for improved performance and an increasingly seamless user experience. This usage scenario covers a range of cases, including wide-area coverage and hotspot, which have different requirements. Massive machine type communications (mMTC): This usage scenario is – characterized by a very large number of connected devices typically transmitting a relatively low volume of non-delay-sensitive data. Ultra-reliable and low latency communications (URLLC): This usage scenario has – stringent requirements for capabilities such as throughput, latency and availability. Some examples include wireless control of industrial manufacturing or production processes, remote medical surgery, distribution automation in a smart grid, transportation safety, etc. 8.2 Test environments A test environment reflects a combination of geographic environment and usage scenario. There are five selected test environments for IMT-2020 as follows: An indoor isolated environment at offices and/or in shopping Indoor Hotspot-eMBB: − malls based on stationary and pedestrian users with very high user density. An urban environment with high user density and traffic loads Dense Urban-eMBB: − focusing on pedestrian and vehicular users. A rural environment with larger and continuous wide area coverage, Rural-eMBB: − supporting pedestrian, vehicular and high speed vehicular users. An urban macro environment targeting continuous coverage Urban Macro–mMTC: − focusing on a high number of connected machine type devices. An urban macro environment targeting ultra-reliable and low Macro–URLLC: − latency communications. The mapping of the five test environments and the three usage scenarios is given in Table 8-1.
