Baseline performance based on 3GPP 3D MIMO of arrival (OTDOA) based positioning for Narrowband Internet of Things (NB-IoT), which will be integrated as a part of the 3rd Generation Partnership Project (3GPP) Long ermT Evolution TE) release 14. ARM Cordio-N IP for NB-IoT will provide the wide area and low power connectivity required for … Following are the applications of OTDOA: • It is used as positioning method in all the LTE enabled mobile phones. • It is used for E911 emergency services in the USA. • It is used for various commercial applications which include maps, location based advertising on the mobile as per interest of the users and search history. OTDOA is a suitable positioning method candidate as it is based on broadcast signals and so enables good scalability which is required for massive IoT scenarios. Considering the different use cases, radio environments, device capabilities and supported bandwidths, NB-IoT and feMTC could properly support the positioning requirements.

Techniques for observed time difference of arrival (OTDOA) positioning based on heterogeneous reference signals (RSs) are discussed. One example  Observed time difference of arrival (OTDOA) is a downlink based positioning method described by 3GPP as one of the NB-IoT positioning methods to increase   Hybrid-GNSS or GNSS + Mobile Radio Cellular Positioning like OTDOA. Control Plane (C-Plane) and User Plane (U-Plane) session handling: LPP, SUPL 2.0. For the multiple OTDOA based positioning, several weighted average method can be utilized by applying equal gain weighting or received power of signals. 3 Feb 2015 (SDR) receiver is developed for OTDoA positioning in LTE. A preliminary scenario with four synchronized base stations is used to validate the  for OTDOA. 36.133 · 0433, RSTD Measurement Requirements for OTDOA 36.133 · 0726, Requirements for reporting criteria with positioning measurements . 6 Jun 2014 UE assisted positioning: the UE provides position measurements to the location server.

In the adopted Observed Time Difference of Arrival (OTDOA) algorithm the base stations transmit so-called Positioning Reference Signals (PRS). PRS Muting Pattern Assignment to Optimize RSTD Measurement Acquisition for OTDOA Positioning in 3GPP LTE. Ramya Srinivasan, Grant A. Marshall, Guttorm R. Opshaug, Borislav Ristic, Kirk A. Burroughs, Sven Fischer, Shuping Zhang, Daniel Henriksson A, François Cardinal The measurements may be for an observed time of arrival difference (OTDOA) positioning method or an extended cell ID (ECID) positioning method. Determining the measured radio source for an ambiguous cell may be used to improve the location estimate for user equipment (UE). OTDOA positioning accuracy is greatly impacted by both the RSTD measurement quality and the position estimation quality. That is to say, a system with a good RSTD measurement quality provided by the UE vendor but a poor position estimation provided by the location server However, an A-GPS positioning and an OTDOA positioning may be initiated in parallel.

ARM Cordio-N IP for NB-IoT will provide the wide area and low power connectivity required for low-end IoT devices. The used positioning technique is known as observed time difference of arrival (OTDOA), because the device measures the arrival time of several transmitted reference signals.

Determining the measured radio source for an ambiguous cell may be used to improve the location estimate for user equipment (UE). OTDOA positioning accuracy is greatly impacted by both the RSTD measurement quality and the position estimation quality. That is to say, a system with a good RSTD measurement quality provided by the UE vendor but a poor position estimation provided by the location server However, an A-GPS positioning and an OTDOA positioning may be initiated in parallel. It is then only when the OTDOA method is the only successful method that the rest of the method 100 is performed. The primary reason for this is that a failure of A-GPS positioning and a success of OTDOA positioning indicates an indoor UE 12 location. LTE Mobile users positioning via OTDOA measurements: modeling and simulation May 2016 Conference: 9 ème édition Journées d’Optique et de Traitement de l’Information JOTIM'16 These positioning methods were chosen as they refer to the three hearability from at least three Node Bs. A simulation model for OTDOA based on the path loss model has been developed and is used to simulate data with fixed input parameters and the RSCP of Node Bs from field drive test. Therefore, how to enhance positioning accuracy raises great awareness and related 5G numerology design is a hot topic.
