The OTDOA-IPDL mechanism is detailed, and implemented in a typical simulation scenario. 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. MediaTek NB-IoT products lead the market with R14 specification adherence. hellaPHY OTDOA thus brings the power and scale of 4G-LTE cellular networks to the problem of the Location of Things.

Here is a short introduction on how the 3GPP R14 specification enhances the NB-IoT protocol for NB2: NB2 positioning. The 3GPP Release 14 introduces OTDOA and E-CID positioning methods into NB2 for higher location accuracy. Multicast in NB2. The NB2 devices contain Multicast transmission mode, which the NB1 device does not have. Enhanced NB2 OTDOAとその利点 3GPPリリース14では、NB-IoTがさらに改善され、ユーザー体感が向上しています。OTDOA（Observed Time Difference Of Arrival）は、ダウンリンクベースの位置決定方法であり、位置決定精度を高めるためのNB-IoT位置決定方法の1つとして3GPPで記述されています。 Difference Of Arrival (OTDOA) Positioning Technique in 3GPP LTE 1Sowmya GM , Nagaraj K2, Sampath Kini3 1PG Student, Dept Of CSE,NMAM Institute Of Technology, Nitte,India 2 Manager-Embedded Product Design, Communications BU ,TATA ELXSI Bangalore, India 3Assistant Professor, Dept Of CSE,NMAM Institute Of Technology,Nitte,India This paper gives an overview of algorithms for positioning a mobile phone using 3GPP-FDD mode signals.

The operation of the OTDOA method is described in clause 8.2. 4.3.4 Enhanced Cell ID methods. In the Cell ID (CID) positioning method, the position of an UE is estimated with the knowledge of its serving ng-eNB, gNB and cell. The information about the serving ng-eNB, gNB and cell may be obtained by paging, registration, or other methods.

• It is assisted by eNB. The uplink transmissions from UE are received by highly sensitive receivers which will determine the time differences of arrival and hence UE position.

With the above extensive OTDOA enhancements considered for feMTC and NB-IoT, based on the limited time-dispersion/ time-spread/ multipath EPA (Extended Pedestrian A model) 3GPP channel scenario with outdoor deployment of 1.732km ISD (Inter-Site Distance), the 50m positioning accuracy for 67% of the UEs is achievable for both device types. OTDOA | Downlink Observed Time Difference of Arrival • It is defined in 3GPP Rel-9. • It is known as downlink Observed Time Difference Of Arrival.

set to be defined in Release 11 as an additional 3GPP LPP technique, is the Sep 11, 2020 This paper adopts the 5G channel model developed by 3GPP TR38.901 estimation algorithm for observed time difference of arrival (OTDOA),. 3GPP (the Third Generation Partnership Project) defines OTDOA by using the Positioning Reference Signal (PRS). [0004] Indoor UEs will experience more Release-15 NR provides support for RAT-independent positioning techniques and Observed Time. Difference Of Arrival (OTDOA) on LTE carriers.
