Abstract

Methods, devices, and systems are described for using multiple measurements including Doppler measurements from a mobile device to identify the position of the base station. Repeated Doppler and velocity measurements from different locations, with measurement groups taken at the same time or within a certain time frame, may be used to identify the location of a base station with which the mobile device is communicating.

First claim

What is claimed is:

1. A method comprising:
determining within a first time period, by a mobile device, (a) a first velocity associated with the mobile device and a first position and (b) a first Doppler measurement between the mobile device and a base station, wherein the first Doppler measurement is referenced to a local stable clock signal of the mobile device;
determining within a second time period, by the mobile device, (c) a second velocity associated with the mobile devi…
