Positioning for the Internet of Things: A 3GPP Perspective
9 3GPP TS 36.355 V13.1.0 (2016-03) Foreword . This Technical Specification has been produced by the 3. rd. Generation Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. The 3GPP consortium responded to this need by enhancing its 4G communication standard (LTE) with positioning capabilities. In the adopted Observed Time Difference of Arrival (OTDOA) algorithm the base stations transmit so-called Positioning Reference Signals (PRS).

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.

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. 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 low-end IoT devices. 3GPP (3rd Generation Partnership Project) has started to discuss D2D (Device-to-Device)-aided OTDOA (Observed Time Difference Of Arrival) as one of the mobile positioning enhancement techniques for LTE (Long Term Evolution) systems.
8.2.1 General. 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 OTDOA is a subscriber location technique which was introduced in Release 9 of the 3GPP specifications. OTDOA is based on the mobile taking TDOA measurements from the PRS (Positioning Reference Signal) associated with the neighbouring eNBs that the mobile is able to receive. The operation of the OTDOA method is described in clause 8.2.
