Ranging refers to the determination of the distance between two UEs or more UEs and/or the direction and/or relative positioning of one UE from another UE via direct communication. Sidelink Positioning is to position a UE using PC5 direct communication.
Ranging based services and Sidelink Positioning technology can be used in a variety of verticals, such as smart home, smart city, smart transportation, smart retail, industry 4.0, V2X and public safety services for in-coverage, partial coverage and out of coverage use cases.
3GPP (3rd Generation Partnership Project), a standard organization for developing cellular telecommunication specifications, has identified the above use cases and the technical requirements, and has established several Release 18 study items on Ranging and Sidelink positioning to specify the radio enhancements, 5GC architectural enhancements and security impacts, which are parts of 5G-Advanced features.
Sherry Shen has about 20 years of telecommunication standardization experience in 3GPP, ITU-T, IETF, GSMA, CCSA, etc., as the delegate representing the employer company (15 years for Nokia and 2 years for Xiaomi). Her rich work experiences in the telecom operator, network equipment vendor and mobile device/IoT/vehicle vendor endow her a broad view of cutting-the-edge technologies in the telecom industry. She has contributed to the 3GPP 5GC work since the beginning of the 5G study, and she is now the rapporteur of FS_Ranging_SL in 3GPP SA2 Working Group.
