U-TDOA | Uplink Time Difference of Arrival • It is defined in 3GPP Rel-11. • It is known as uplink Time Difference Of Arrival. • 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. 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".

Performance of OTDOA positioning in narrowband IoT systems. K Radnosrati, G Localization in 3GPP LTE based on one RTT and one TDOA observation.

3GPP Rel-9[4], in which Reference Signal Partnership Project (3GPP) consortium [1], has defined a dedicated downlink signal for Observed Time Difference of Arrival (OTDoA) positioning, i.e. the Feb 4, 2013 This includes observed time difference of arrival (OTDOA) based methods such as PRS as well as enhanced cell ID based positioning. Mar 1, 2011 A fresh push for location services in 3GPP started in 2009 for LTE Release 9 ( OTDOA and ECID function only in UE-assisted mode in LPP).

The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Enhanced Cell ID, E-CellID, or E-CID is a positioning feature introduced in rel9 E-UTRA (LTE radio).

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.
