Abstract: A wireless remote unit performs SPS acquisition interleaved with receiving paging information over a wireless slotted paging channel and receiving data packets over a wireless data communication system. The remote unit tunes to a pilot channel, synchronizes to an internal clock of the wireless remote unit with a pilot signal transmitted over the pilot channel; and starts a search for SPS satellites after completing synchronization with the internal clock.

Abstract: A method for blindly determining positioning reference signals in a wireless communication network determines a positioning reference signal (PRS) network configuration by estimating a PRS energy from predetermined locations of each subframe of an incoming signal. Such a method may also include blindly detecting PRS parameters based on the estimated PRS energy. The PRS energy may be peak energy responses for deep searches or verifications. The PRS energy may be a signal to signal plus noise ratio for shallow searches.

Abstract: A position determination system and apparatus for utilizing a network of cellular base stations to determine position of a mobile station includes taking a plurality of statistically independent data measurements of the pilot signals from the base stations. Each of the data measurements includes an earliest time of arrival, providing multiple independent measurements for each of the pilot signals. For each cellular base station, a representative measurement is calculated responsive to the independent measurements, which is used to determine position of the mobile station using an AFLT algorithm and/or in conjunction with a GPS algorithm. In some embodiments, the data measurements for each pilot signal further include an RMSE estimate and time of measurement for each time of arrival, and an energy measurement for all resolvable paths. If the mobile station comprises a cell phone, a cell search list and a GPS search list may be provided by a cell base station.

Abstract: A system for optimizing power use in a wireless communication device includes a selectively activated first timer which has a first level of power consumption and which generates a first time signal with a first level of accuracy. A selectively activated second timer has a second level of power consumption, less than the first level of power consumption, generates a second time signal with a second level of accuracy less than the first level of accuracy. A selectively activated position determination receiver has a third level of power consumption, and receives signals that permit position determination using the received signals and either the first or the second time signal. A selection processor selectively activates either the first or the second timer for use with the position determination receiver to optimize power consumption of the wireless communication device.

Abstract: The maximum system time uncertainty for a mobile station in a wireless communications system using GPS signals for position determination is minimized by using aiding information from base stations, such as neighbor search window size (NSWS) parameters or neighboring pilot measurements (NPM). Knowledge of the last successful position determination fix (LSPDF) and the speed of the mobile station may also be used. In one embodiment, a weighted combination of estimates based on NSWS parameters, neighboring pilot measurements and/or last successful position determination fix is used. The search time window is then proportional to the maximum system time uncertainty plus position uncertainty.

Abstract: A parameter estimator for estimating one or more parameter(s) from a correlation function derived from a signal using a dynamically variable integration time is described. The parameter estimator may be employed in a subscriber station to estimate the time of arrival of one or more base station or sector pilot signals in a wireless communication system. This information may be utilized in an overall advanced forward link trilateration (AFLT) process for estimating the location of the subscriber station.
