21, D-80333 München, Germany All results are summarized in the technical report 3GPP TR 37.857 "Study on Indoor Positioning Enhancements for UTRA and LTE", available from the 3GPP web site. We in Ericsson recently presented some of the results at the International Conference on Localization and GNSS (ICL-GNSS) conference, in the paper "Baseline Performance of LTE Positioning in 3GPP 3D MIMO Indoor User Scenarios". 8.2.1 General. In this version of the specification, only OTDOA based on LTE signals is supported.

OTDOA is a subscriber location technique which was introduced in Release 9 of the 3GPP specifications. OTDOA is based on the mobile taking TDOA measurements from the PRS (Positioning Reference Signal) associated with the neighbouring eNBs that the mobile is able to receive.

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. OTDOA is based on the mobile taking TDOA measurements from the PRS (Positioning Reference Signal) associated with the neighbouring eNBs that the mobile is able to receive. The operation of the OTDOA method is described in clause 8.2. 4.3.4 Enhanced Cell ID methods. 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 operation of the OTDOA method is described in clause 8.2. 4.3.4 Enhanced Cell ID methods. 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.

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. As the reference signal PRS is used here for UE to measure the time difference, the OTDOA is referred to as the reference signal time difference (RSTD) in terms of 3GPP LTE. Similarly, for E-CID, the so-called UE Rx–Tx time dif- ference is measured.
