This downlink-based localization approach Nov 30, 2018 Enhanced assistance messaging scheme for GPS and OTDOA Very good alignment between 5GCAR activities and ongoing 3GPP NR The 3GPP categorizes the main localization use cases based on verticals, briefly Clearly, OTDOA is a UE-based positioning method which requires a specific. PRS Muting Pattern Assignment to Optimize RSTD Measurement Acquisition for OTDOA Positioning in 3GPP LTE. R Srinivasan, G Marshall, G Opshaug, Dec 7, 2018 Reference [3] provides details of OTDOA in LTE. Enhance Cell Id (E-CID) is a feature introduced in. 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).

Performance of OTDOA Positioning in Narrowband IoT Systems Kamiar Radnosrati, Gustaf Hendeby, ing support since 3GPP Release 9. The subsequent releases, as 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 described by 3GPP as one of the NB-IoT positioning methods to increase positioning accuracy.

Speciﬁcally, for in-band deployment, PRS symbols are reused also in the NPRS, which typ-ically is extended with a large number of repetitions to allow accumulation at the device for detectability. OTDOA positioning in legacy LTE systems is widely studied in the literature. S. Fischer, Observed Time Difference of Arrival (OTDOA) Positioning in 3GPP LTE, Qualcomm Technologies, Inc., June 2014.
