7.9 KPIs for ranging based services |R18| p. 103

In several scenarios, it can be beneficial to determine the distance between two UEs and/or the direction of one UE from the other one via direct communication connection. The functional requirements related to ranging based services can be found in clause 6.37. Performance requirements for ranging based services in different scenarios can be found in Table 7.9-1.

Key performance indicators and key attributes for ranging are defined as follows:

Ranging accuracy: describes the absolute value of the deviation of the measured distance and/or direction between two UEs to the true distance and/or direction value.
Confidence level: describes the percentage of all the possible measured distance and/or direction that can be expected to include the true distance and/or direction considering the ranging accuracy.
Effective ranging distance: the largest distance between the UE who initiates the ranging and target UEs in the ranging operation.
Line-of-sight (LOS) Environment: the environment between the UE who initiates the ranging and target UEs, such as LOS and non-LOS (NLOS).
Coverage: type of radio coverage conditions of the UEs who are involved in ranging, such as in coverage (IC), partial coverage (PC) and out of coverage (OOC). See also Figure 6.37.1-1.

NOTE:
If using licensed spectrum, ranging is only permitted in network coverage under the full control of the operator who provides the coverage, except for public safety networks with dedicated spectrum where ranging might be allowed out of coverage or in partial coverage as well.
Relative UE velocity: the target UE can be either static or mobile relative to the UE who initiates the ranging. In the latter, the attribute shall also provide some elements about its motion, e.g. maximum speed, trajectory.
Availability: percentage value of the amount of time when a ranging system is able to provide the required ranging-related data within the performance targets or requirements divided by the amount of time the system is expected to provide the ranging service in a targeted service area.
Latency: time elapsed between the event that triggers the determination of the ranging-related data and the availability of the ranging-related data at the ranging system interface.
Ranging interval: time difference between two consecutive ranging operations.
