Introduction to OTDOA on LTE Networks How does OTDOA work 7 Since each TOA measurement τ i has a certain accuracy and uncertainty, the hyperbolas in Figure 1-1are shown with a certain width, illustrating the measurement uncertainty.

This approach requires accurate Angle of Arrival In this tutorial, the state of art of mobile location based services , which is only useful for location estimation, randomly, pseudo- randomly or periodically. • OTDOA of these common pilots is measured in the mobile for different Node Bs. Compared with standard IPDL, TA-IPDL • is more accurate, • reduces the mobile complexity. For example, in 3GPP Release 9, the primary positioning method is A‐GPS (Assisted Satellite Positioning), while the fall‐back methods are ECID (enhanced cell identity) and OTDOA (observed time difference of arrival). CID (cell ID) method returns the location of the cell or antenna serving the MS during a call as its position estimate. 2020-05-22 Welcome to the Ericsson Blog.

LTE Observed Time Difference of Arrival (OTDOA) method in the other hand uses the measured timing of downlink signals received from multiple eNBs to locate the UE according to the neighboring eNBs. OTDOA can be supplement AGPS in dense urban and indoor areas where UE can detect position reference signals (PRS) from three or more eNBs.

PRS Muting Pattern Assignment to Optimize RSTD Measurement Acquisition for OTDOA Positioning in 3GPP LTE. Ramya Srinivasan, Grant A. Marshall, Guttorm R. Opshaug, Borislav Ristic, Kirk A. Burroughs, Sven Fischer, Shuping Zhang, Daniel Henriksson A, François Cardinal Abstract: Abstract—This contribution describes the first implementation of an integrated modem supporting NB-IoT OTDOA positioning. The integration of a dedicated hardware accelerator provides the necessary processing power for time-domain cross-correlations of OFDM signals and enables successful position fixes at highly negative SINR.

OTDOA for E-UTRAN (i.e. on LTE networks) is introduced in this whitepaper. 3 In 3GPP LTE specifications, a User Equipment (UE) refers to a Mobile Station (MS) and an eNodeB (eNB) refers to a Base Station (BS). In this whitepaper, UE and eNodeB/eNB are used synonymously for MS and BS.

PF Paging frame. PH Paging hyperframe. tutorial, we focus only on the in-band operation mode as it. OTDOA is a handset-based technology that relies on measurement of the time difference of arrival of special Positioning Reference Signals (PRS) from 2 or more neighboring LTE base stations.

OTDOA can be supplement AGPS in dense urban and indoor areas where UE can detect position reference signals (PRS) from three or more eNBs. This example shows how to use the Time Difference Of Arrival (TDOA) positioning approach in conjunction with the Release 9 Positioning Reference Signal (PRS) to calculate the position of a User Equipment (UE) within a network of eNodeBs using the LTE Toolbox™. This page compares GPS vs U-TDOA and mentions difference between GPS and U-TDOA.GPS stands for Global Positioning System and U-TDOA stands for Unlink Time Difference of Arrival.U-TDOA is uplink method similar to downlink OTDOA.

In this basic tutorial, (OTDOA) on LTE carriers. Release 16 extends NR to provide native positioning support by introducing RAT-dependent positioning schemes. 63IEEE ICC 2008 - Beijing OTDOA with IPDL for UMTS (1/2) • Idle Period Downlink (IPDL) is a techniques used by UMTS network, where Node B transmissions are synchronously ceased for a short period of time. • Mobiles measure the OTDOA of each neighbor Node B’s pilot signals during the IPDLs of serving BTS. Abstract: Abstract—This contribution describes the first implementation of an integrated modem supporting NB-IoT OTDOA positioning. The integration of a dedicated hardware accelerator provides the necessary processing power for time-domain cross-correlations of OFDM signals and enables successful position fixes at highly negative SINR.

In this whitepaper, UE and eNodeB/eNB are used synonymously for MS and BS. This page covers OTDOA (Observed Time Difference of Arrival) basics.It mentions how OTDOA works in LTE system and mentions applications of OTDOA.The advantages or benefits of OTDOA are also mentioned.The links to comparison between OTDOA with GPS and U-TDOA are also mentioned.

Customize It: • If you are familiar with some aspects of LTE Location Based Services Training, we can omit or shorten their discussion. • We can adjust the emphasis placed on the various topics or build the LTE Location Based Services Training course around the mix of technologies of interest to you (including technologies other than those included in this outline).

This video is focused on a location technology that just about all LTE-enabled mobile devices need to support. Observed time difference of arrival, or OTDOA, OTDOA — This method uses the measured timing of downlink signals received from multiple eNBs to locate the user device in relation to neighboring eNBs. In dense urban and indoor environments, OTDOA can be used to supplement AGPS, provided the user device can detect position reference signals (PRS) from three or more eNBs.

This technology is most useful when GNSS is not available because it can provide reasonably accurate positioning (about 25-200m) indoors or in environments with limited visibility of the sky.
