• 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. 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?

8.2.1 General. In this version of the specification, only OTDOA based on LTE signals is supported. 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.

LTE Positioning Methods- overview 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. serving cell in the UE OTDOA is an abbreviation for Observed Time Difference of Arrival, and it is a downlink based multilateration positioning method introduced in the LTE 3GPP Release 9. How does OTDOA NB-IoT positioning work? 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.
