The UE reports to the network the serving cell ID, the timing advance (difference between its transmit and receive time) and the IDs, estimated timing and power of the detected neighbor cells.The enodeB may report extra information to the ESMLC like the angle of arrival. 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.

OTDOA † The server asks the UE locate itself † Provides also satellite assistance data to aid detection † Satellite based positioning is radio system agnostic † LTE just provides a connection between the UE and the server † The server provides the UE with a list of potential neighbors cells to search † The UE measures and reports OTDOA Narrowband Internet of Things (NB-IoT) is an emerging cellular technology designed to target low-cost devices, high coverage, long device battery life (more than ten years), and massive capacity. We investigate opportunities for device tracking in NB-IoT systems using Observed Time Difference of Arrival (OTDOA) measurements.
