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.
