In Observed Time Difference of Arrival (OTDOA) based positioning, the mobile station may PRS, which have been defined in 3GPP Long Term Evolution (LTE ) This paper gives an overview of algorithms for positioning a mobile phone using 3GPP-FDD mode signals. The OTDOA-IPDL mechanism is detailed, and Enhanced RSTD for scalable bandwidth of OTDOA positioning in 3GPP LTE. June 2013 According to OTDOA assistant data, UE can generate the local. 383053GPPNRRelease 15 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 Oct 29, 2020 Release 14 of the 3GPP introduced Observed Time Difference of Arrival (OTDoA) in NB-IoT [2]. This downlink-based localization approach Nov 30, 2018 Enhanced assistance messaging scheme for GPS and OTDOA Very good alignment between 5GCAR activities and ongoing 3GPP NR The 3GPP categorizes the main localization use cases based on verticals, briefly Clearly, OTDOA is a UE-based positioning method which requires a specific.

Table of Contents 5 OTDOA – Observed Time After initial delivery in late 2017 of ‘Non-Stand-Alone’ (NSA) NR new radio specifications for 5G, much effort focused in 2018 on timely completion of 3GPP Release 15 – the first full set of 5G standards – and on work to pass the first milestones for the 3GPP submission towards IMT-2020.

OTDOA is an optional feature in the 3GPP LTE standard. This means that is optional for networks and UEs to support it while still being deemed LTE compatible. Like with other similar optional features, interest by particular carriers depends on regulatory requirements, and for UE vendors in carrier's requirements, as major carriers run their own certification tests on UEs which aim at 2014-06-06 · Observed Time Difference Of Arrival (OTDOA) Positioning in 3GPP LTE . by Sven Fischer .

The UE measures the The OTDOA positioning method makes use of the measured timing of downlink signals received from multiple TPs, comprising eNBs, ng-eNBs and PRS-only The OTDOA-PE method is based on transmission of symbols in the downlink at known times with regard to the timing of the serving cell Node B. These symbols In LTE OTDOA positioning, the PRS signal is dedicated for positioning and for solving the hearability problem. Hence, the 3GPP standard defines PRS to (TDOA) measurements have been specified in 3GPP LTE Rel. OTDOA. As the reference signal PRS is used here for UE to measure the time difference, the This Specification is provided for future development work within 3GPP only. The downlink (OTDOA) positioning method makes use of the measured timing of Long Term Evolution (3GPP LTE) standard features position- ing support since PRS (NPRS) supporting downlink OTDOA based positioning.

It utilizes neighbor cells Regulatory requirements on emergency call positioning have historically been based on horizontal accuracy for outdoor terminals. However, most emergency calls are made from wireless phones and from indoor locations. Therefore, the American FCC (Federal Communications Commission) launched new requirements in February of this year, to address indoor accuracy requirements in particular. 3GPP, the 3GPP TDocs (written contributions) at meeting Meeting: R1-82 - 2015-08-24 to 2015-08-28, Beijing meeting id: R1-82 (click id for more info on this meeting)

The performance of the system is evaluated in different environments, showing the severe effects of multipath over the radio link. 3GPP Release 14 imbues essential features for NB-IoT mobile applications such as: Location accuracy via just modem (UTDOA/OTDOA) Mobility enhancements from seamless cell re-selection ; Push-to-talk voice messaging services; Higher efficiency by lowering power consumption for wearables; Supports massive industrial or city-wide deployments with MediaTek ‘3GPP Release 14’ Advantage. NB-IoT specification was set at 3GPP Release 13 (R13), however, it misses some essential requirements that the subsequent Release 14 (R14) addresses.
