Location Based Service in Cellular Networks: from GSM to 5G NR

The proposed new NR-RACH Positioning (NRPos) uses the timing advance parameter in random access response (RAR) of a random-access request to achieve better accuracy than state-of-the-art localization systems like observed time difference of arrival (OTDOA), enhanced 5G Positioning and Location Services is a 2-day training program covers 5G new enhanced parameters for positioning accuracy down to the meter, decimeter and centimeter. In this technical course, we break down the accuracy requirements of emerging 5G use cases and explore the key features of new 3GPP 5G positioning architecture. 27 3GPP TS 22.261 Service requirements for the 5G system; Stage 1 28 3GPP TS 22.104 Service requirements for cyber-physical control applications in vertical domains 29 3GPP TS 28.541 5G Network Resource Model (NRM); Stage 2 and stage 3 Conventions If the document includes binding material, this section shall contain the following statement, Toktam Mahmoodi – List of Publications – Chronological Order 2019 90. Book chapter: “Haptic Networking Supporting Vertical Industries” in “Enabling 5G Communication Systems to Support Vertical Industries”. Luis Sequeira, Konstantinos Antonakoglou, Maliheh Mahlouji, and … In this version of the specification, only OTDOA based on LTE signals is supported. In the OTDOA positioning method, the UE position is estimated based on measurements taken at the UE of downlink radio signals from multiple E-UTRA TPs (possibly including PRS-only E-UTRA TPs from a PRS-based TBS), along with knowledge of the geographical coordinates of the measured TPs and their relative downlink timing.

In dense urban and indoor environments, OTDOA can be used to supplement AGPS, provided the user device can detect position reference signals (PRS) from three or more eNBs. Geofencing in 5G – “3GPP Release 15 will use LPP as a positioning protocol and support the associated positioning methods such as Global Navigation Satellite System (GNSS) and Observed Time Difference of Arrival (OTDOA)). As the 5G standard evolves and matures, 5G-specific positioning methods and protocols will find their way into 5G geofencing.” This page compares GPS vs U-TDOA and mentions difference between GPS and U-TDOA.GPS stands for Global Positioning System and U-TDOA stands for Unlink Time Difference of Arrival.U-TDOA is uplink method similar to downlink OTDOA.
