Lo´pez-Salcedo, Senior Member, IEEE, and Gonzalo Seco-Granados, Senior Member, IEEE Abstract—Cellular systems evolved from a dedicated mobile WPI - with Byron Chen, Lead SE for E911/LBS in LTEi, Alcatel-Lucent LTE Release 9 adds several new features to LTE, such as evolved MBMS (eMBMS), dual-layer beamforming (transmission mode 8) and positioning support. To suppor OTDOA positioning method (network based) A-GNSS based positioning methods (handset based) UTDOA positioning method (network based) LCS Procedures in UMTS. GL’s MAPS™ LCS test suite comprises of multiple products working in tandem to support simulation of end-to-end location based services in GSM, UMTS, and LTE networks.

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, Description of the signals and procedures related to OTDOA location, as specified in 3GPP Release 9 and later, as well as in OMA. Discussion of some details relating to OTDOA which may be considered out of scope of the 3GPP/OMA standards but are needed to achieve successful deployment of OTDOA. OTDOA (Observed Time Difference Of Arrival) is a positioning feature introduced in rel9 E-UTRA (LTE radio). It's a multilateration method in which the User Equipment (UE) measures the time difference between some specific signals from several eNodeBs and reports these time differences to a specific device in the network (the ESMLC). The ESMLC based on these time differences and knowledge of the enodeBs locations calculates the UEs' position. OTDOA — This method uses the measured timing of downlink signals received from multiple eNBs to locate the user device in relation to neighboring eNBs.

The use of a combination of technologies OTDOA uses LMUs to calibrate the downlink measurements from neighbor base stations for individual mobile users. If measure-ments from three or more stations are available, a position can be estimated [1]. Considering the similarities between the systems, we can view OTDOA as a … In the second part of the tutorial details on theoretical and practical issues about fingerprinting approaches, implemented by using the WLAN (or a 5G femtocell), will be provided.

This page compares OTDOA vs U-TDOA and mentions difference between OTDOA and U-TDOA.OTDOA method measures UE position based on downlink signal measurement while U-TDOA method measures UE position based on uplink signal measurement. Like downlink OTDOA; the method used to determine position of UE using uplink transmissions is known as U-TDOA. Refer OTDOA basics and working >> . Following table mentions difference between GPS and OTDOA methods used to determine position of UE. OTDOA for Wideband CDMA (WCDMA) Observed TDOA (OTDOA), as its name indicates, is a TDOA-based approach. It is designed to operate over wideband-code division multiple access (WCDMA) networks. Similar to the E-OTD, OTDOA uses LMUs to calibrate the downlink measurements from neighbor base stations for individual mobile users. such as OTDOA, can be a better choice for indoor locations and urban canyon environments, while Adaptive Enhanced Cell Identity (AECID) is a good fit in all environments and is especially suitable for terminals that are not equipped with GNSS receivers.

SELF-LEARNING AND METHOD SELECTION WPI - with Byron Chen, Lead SE for E911/LBS in LTEi, Alcatel-Lucent 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. OTDOA for Wideband CDMA (WCDMA) Observed TDOA (OTDOA), as its name indicates, is a TDOA-based approach. It is designed to operate over wideband-code division multiple access (WCDMA) networks.
