How does OTDOA NB-IoT positioning work? 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. S.

The uplink transmissions from UE are received by highly sensitive receivers which will determine the time differences of arrival and hence UE position. Maximum likelihood TOA and OTDOA estimation with ﬁrst arriving path detection for 3GPP LTE system W. Xu 1*, M. Huang , C. Zhu2 and A. Dammann3 1 Intel Mobile Communications, Am Campeon 10-12, D-85579 Neubiberg, Germany 2 Technische Universität München, Arcisstr. 21, D-80333 München, Germany All results are summarized in the technical report 3GPP TR 37.857 "Study on Indoor Positioning Enhancements for UTRA and LTE", available from the 3GPP web site. We in Ericsson recently presented some of the results at the International Conference on Localization and GNSS (ICL-GNSS) conference, in the paper "Baseline Performance of LTE Positioning in 3GPP 3D MIMO Indoor User Scenarios". 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.

your NB-IoT OTDOA positioning design OTDOA and its advantages 3GPP Release 14 further improves NB-IoT to enhance the user experience. 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. 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)
