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).

Refer OTDOA basics and working >>. 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.

Long Term. Evolution (LTE) systems have an  We focus on OTDOA, which is a downlink based positioning method. We provide an overview of the OTDOA architecture and protocols, summarize the designs  OTDOA (Observed Time Difference Of Arrival) är en positioneringsfunktion introducerad i rel9 E-UTRA OTDOA är en valfri funktion i 3GPP LTE- standarden. Performance of OTDOA positioning in narrowband IoT systems.

Ramya Srinivasan, Grant A. Marshall, Guttorm R. Opshaug, Borislav Ristic, Kirk A. Burroughs, Sven Fischer, Shuping Zhang, Daniel Henriksson A, François Cardinal Initial deployment of 3GPP-LTE is expected in 2009 and recent news has been announced that a contract of commercial LTE network in Stockholm is signed between TeliaSonera and Ericsson. An initiative has been taken by 3GPP to plan the future work for LTE, referred as LTE-Advanced [6].

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.

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.
