3GPP Release 14 imbues essential features for NB-IoT mobile applications such as: Location accuracy via just modem (UTDOA/OTDOA) Mobility enhancements from seamless cell re-selection ; Push-to-talk voice messaging services; Higher efficiency by lowering power consumption for wearables; Supports massive industrial or city-wide deployments with

• 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? Another method for NB-IoT positioning in 3GPP R14 is Enhanced Cell ID (E-CID), based on Cell of Origin (COO).

The UE measures the The OTDOA positioning method makes use of the measured timing of downlink signals received from multiple TPs, comprising eNBs, ng-eNBs and PRS-only The OTDOA-PE method is based on transmission of symbols in the downlink at known times with regard to the timing of the serving cell Node B. These symbols In LTE OTDOA positioning, the PRS signal is dedicated for positioning and for solving the hearability problem. Hence, the 3GPP standard defines PRS to (TDOA) measurements have been specified in 3GPP LTE Rel. OTDOA. As the reference signal PRS is used here for UE to measure the time difference, the This Specification is provided for future development work within 3GPP only.

[0004] Indoor UEs will experience more Release-15 NR provides support for RAT-independent positioning techniques and Observed Time.

Observed time difference of arrival (OTDOA) is a downlink based positioning method de-scribed by 3GPP as one of the NB-IoT positioning methods to increase positioning accuracy. It utilizes neighbor cells Regulatory requirements on emergency call positioning have historically been based on horizontal accuracy for outdoor terminals. However, most emergency calls are made from wireless phones and from indoor locations. Therefore, the American FCC (Federal Communications Commission) launched new requirements in February of this year, to address indoor accuracy requirements in particular.
