About Qualcomm Careers Offices Contact Us Downlink OTDOA is specified in 3GPP Release-9. • In uplink OTDOA, eNBs receive the uplink transmission from UE and determines position of UE. Uplink OTDOA (U-TDOA) is specified in 3GPP Release-11. How OTDOA Works • OTDOA uses hyperbolic multilateral algorithm to determine time of arrival of downlink signals from multiple eNBs (includes 1 3GPP Release 9 OTDOA (Observed Time Difference of Arrival) † UE location can be tri-laterated with the knowledge of three or more eNB’s –Transmit timings of the cells in the system and their geographical locations –Received time difference of at least two other cells vs.

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. The Observed Time Difference of Arrival (OTDoA) technology defined in the 3GPP-LTE Release 9 standard is based on the Time Difference of Arrival (TDoA) method using the positioning reference 3GPP Portal home page 3GPP public web site Directory. Browse FTP. Help New OTDOA Cat M1/M2 inter-freq reporting accuracy enhanced mode tests: R5-181586: agreed: Narrowband PRS (NPRS) supporting downlink OTDOA based positioning. 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.

Release 9 specification of the Third Generation Partnership Project (3GPP) provided support to Observed Time Difference of Arrival (OTDOA) based positioning Localization in 3GPP LTE Based on One RTT and One TDOA Observation.

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.

Measurement (RSTD), specified in 3GPP TS 36.214 [5]. LTE-M is a cellular radio access technology specified by 3GPP in Release 13, 14 and 15. (OTDOA) and enhanced cell identity (E-CID) are specified in 3GPP.

Like with other similar optional features, interest by particular carriers depends on regulatory requirements, and for UE vendors in carrier's requirements, as major carriers run their own certification tests on UEs which aim at 2014-06-06 · Observed Time Difference Of Arrival (OTDOA) Positioning in 3GPP LTE . by Sven Fischer .
