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.

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.

serving cell in the UE Assisted Satellite positioning (A-GPS, etc) Another new OTDOA functionality in the 3GPP R14 specification is the possibility of multiple PRS transmission configurations to enable higher positioning accuracy. How does E-CID positioning works in NB-IoT? Another method for NB-IoT positioning in 3GPP R14 is Enhanced Cell ID (E-CID), based on Cell of Origin (COO). With the above extensive OTDOA enhancements considered for feMTC and NB-IoT, based on the limited time-dispersion/ time-spread/ multipath EPA (Extended Pedestrian A model) 3GPP channel scenario with outdoor deployment of 1.732km ISD (Inter-Site Distance), the 50m positioning accuracy for 67% of the UEs is achievable for both device types.
