"METHOD FOR CALCULATING REPRODUCED PROPAGATION RETURN TO A USER EQUIPMENT IN A WIRELESS NETWORK, METHOD OF DETERMINING A USER EQUIPMENT THROUGH A SERVER SERVICE SERVICE IN A WIRELESS SERVICE LOCALIZATION SERVICE LOCATION IN A WIRELESS COMMUNICATION SYSTEM AND USER EQUIPMENT IN A WIRELESS COMMUNICATION SYSTEM ". A method of determining the location of a user equipment includes determining a round trip time for downward communication of at least three nodes to a user equipment, determining transmission sync delay on the user equipment to the round-trip time of each of the three nodes, and the determination of a distance from each of the at least three nodes using the round-trip time and transmission synchronization delay.
