Section: 6.37.1 Description
Content: Ranging-based services are the applications utilizing the distance between two UEs and/or the direction of one UE from the other one. In 3D case, direction includes horizontal direction and elevation direction. Ranging-based services can apply to a variety of verticals, such as consumer, smart home, smart city, smart transportation, smart retail, and industry 4.0. Some ranging-based services can only require the distance measurement, some can only require direction measurement, others can require both distance and direction measurement. Ranging can be supported with or without 5G coverage and figure 6.37.1-1 is an illustration of ranging between UEs that are in coverage, out of coverage, or with partial coverage. Both licensed and unlicensed spectrum can be used for ranging. If licensed spectrum is used, it shall be fully under operator control.
