Method for calculating true round trip propagation delay and user equipment location in WCDMA / UTRAN

摘要

A method of determining the location of a user equipment includes determining a round trip time for downlink from at least three nodes to a user equipment, determining the transmission timing delay at the user equipment for the round trip time of each of the three nodes, and determining a distance from each of the at least three nodes using the round trip time and the transmission timing delay.
