slide1. Discussion on the definition and KPIs for FS_Sensing Huawei<br>
slide2. Sensing definition NR wireless sensing: NR based wireless sensing technologies aiming at acquiring information about a remote object and its characteristics without physically contacting it.
NOTE: Certain use cases (e.g. detection of UE’s significant location change) might alternatively be satisfied using information already available in EPC and E-UTRA. In such cases, the available information can be used. This study will not lead to impacts on EPC and E-UTRA.
Reason for the proposal: following the descriptions from agreed SP-220717 (SA#96, 07 – 10 June 2022, Budapest) Wireless sensing technologies aim at acquiring information about a remote object and its characteristics without physically contacting it. NOTE1: Use cases will focus on NR based sensing and could include non-3GPP type sensors (e.g. Radar, camera).
NOTE2: Certain use cases (e.g. detection of UE’s significant location change) might alternatively be satisfied using information already available in EPC and E-UTRA. In such cases, the available information can be used. This study will not lead to impacts on EPC and E-UTRA.<br>
slide3. Definition of KPIs Key performance indicators and key attributes for FS_Sensing are proposed to be defined as follows:
sensing accuracy: the difference between the estimated or measured result at a given time and its true value.Â
sensing resolution: the ability to distinguish between two or more objects that are very close in either distance, angle or velocity.
Effective sensing distance: the maximum distance between the object and either the sensing transmitter or the sensing reflected signal receiver, whichever has the larger distance from the object.
Effective sensing velocity: the speed of the object relative to either the sensing transmitter or the sensing reflected signal receiver, whichever has larger difference in relative velocity from the object.
confidence level: describes the percentage of all the possible measured results that can be expected to include the true value considering the sensing accuracy.
latency: time elapsed between the event that triggers the determination of the sensing-related data and the availability of the sensing-related data. Definition for positioning/ranging topic from 22.261:
positioning service latency: time elapsed between the event that triggers the determination of the position-related data and the availability of the position-related data at the system interface.
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. Definition for ranging topic from 22.261:
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.<br>
