    摘要: A system and method for estimating a location of a wireless device receiving signals from plural nodes of a Code Division Multiple Access 2000 communications system. One or more ranges of a wireless device from one or more of the plural nodes may be determined as a function of signals received at the wireless device from the respective one or more plural nodes and as a function of information in an uplink pilot signal. From one or more location measurement units (“LMU”) measurements an uplink time of arrival (“TOA”) measurement from the device may be determined and then an estimation of the location of the wireless device determined as a function of the uplink TOA and determined one or more ranges.
