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.

Positioning for the Internet of Things: A 3GPP Perspective

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. Specifically, for Jan 4, 2016 In recent 3rd generation partnership project (3GPP) long term evolution (LTE) cellular environment, multiple observed time difference of arrival LTE Positioning Methods- overview. 3GPP Release 9.

Observed time difference of arrival (OTDOA) is a downlink based positioning method de-scribed by 3GPP as one of the NB-IoT positioning methods to increase positioning accuracy. 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.
