Usage scenario Test environment Description An indoor isolated environment at offices and/or in Indoor Hotspot-eMBB shopping malls based on stationary and pedestrian users with very high user density An urban environment with high user density and traffic Dense Urban-eMBB loads focusing on pedestrian and vehicular users A rural environment with larger and continuous wide Rural-eMBB area coverage, supporting pedestrian, vehicular, and high speed vehicular users URLLC Urban Macro-URLLC An urban macro-environment targeting ultra-reliable and low latency communications Urban Macro-mMTC An urban macro-environment targeting continuous coverage focusing on a high number of connected machine type devices As shown in the above table, some of the requirements are associated with the follow- ing five test environments taking into account the three major usage scenarios (eMBB, URLLC, and mMTC) envisaged in IMT-2020 (see Table 2.5). 3GPP has submitted its proposal to the ITU's IMT-2020 development process, which was explained above. The proposal is "5G" developed by 3GPP, i.e., Release 15 and beyond, in accordance with (1) a set of radio interface technologies (SRITs) with new radio (NR) and E-UTRA (Evolved Universal Terrestrial Radio Access)/Long Term Evolution (LTE) and (2) a radio interface technology (RIT) with NR only. These 3GPP technologies are expected to be included in the ITU-R Recommendation on the radio interface tech
