    摘要： In a radio frequency (RF) receiver, a receiver RF chain is tuned to a first (e.g., global positioning system (GPS)) channel to permit receipt of a first (e.g., GPS) signal over the first (e.g., GPS) channel on the receiver RF chain during a first time duration. The receiver RF chain is tuned to a second (e.g., cellular page) channel to permit receipt of a second (e.g., cellular page) signal over the second (e.g., cellular page) channel on the receiver RF chain during a second time duration, following the first time duration. The first (e.g., GPS) signal is processed during the first time duration and the second time duration, without any apparent interruption of the first (e.g., GPS) signal during the second time duration. The processing, for example, provides a bridge signal (e.g., an estimated GPS signal on the receiver RF chain) during the second time duration.

    摘要： Techniques are provided which may be implemented using various methods and/or apparatuses in a receiver and/or other like device to determine an SPS time using SPS signals based on a correlation process. A verification process may be performed, for example, that verifies a maximum peak in comparison with other peak information resulting from the correlation process, for example, by considering a ratio of a maximum peak to a next maximum peak. A time-setting algorithm may be selected, for example, based, at least in part, on a time uncertainty and/or on a type of demodulation performed on the SPS signal. The time-setting algorithm may operatively control one or both of the correlation and/verification processes in a desired manner given the time uncertainty and/or type/mode of demodulation performed.

    摘要： An apparatus and method for determining a position of a mobile station based on terrestrial assistance data from a first wireless network to which the mobile station is not attached. That is, the mobile station is able to receive terrestrial assistance from a first wireless network and use the terrestrial assistance data to obtain location information, such as timing measurements, from the first wireless network and determine its position while not attached to the first wireless network. The first wireless network may be a network to which the mobile station is subscribed and can attach.
