摘要： An image capturing device of a wireless device is used to aid in location determination of the wireless device using imaging techniques. A scene is selected, an image of the scene is formed, and the image is then processed to determine location information based on the image. The location information is then displayed on tie wireless device or sent to a requesting entity. The scene may include a familiar landmark, a street sign or a coded sign with location information. Additionally, the scene may include an optical source transmitting an optical signal with location information.

摘要： At the mobile station the measured pilot energy of each pilot in the candidate set is iteratively compared against a threshold generated in accordance with the sum of the energies of the pilots in the active set. If the strongest pilot in the candidate set satisfies this threshold condition, it is added to the revised active set. A second iterative process is performed to determine whether a pilot should be deleted from the revised active set. The mobile station determines whether a change to the current active set is desirable by measuring the energies of the pilots in the active set and the candidate set, and dynamically adjusting the necessary thresholds based on its own estimation of the communication environment.

摘要： A system and method for dynamically calibrating a base station in a wireless communication system, is presented herein. In accordance with an embodiment of the invention, the system includes a base station for transmitting, receiving, and processing communication signals and a wireless communication device for communicating with the base station. The wireless communication device is configured to determine its location (e.g., using GPS information), to detect the arrival time of a first signal transmitted from the base station, and to calculate a line-of-sight (LOS) delay corresponding to the LOS distance between the wireless communication device and the base station. The LOS distance calculation is based on the base station location information and the wireless communication device location information. The base station measures a round trip delay (RTD) corresponding to the delay incurred by the first signal and a delay incurred by a second signal transmitted from the wireless communication device back to the base station in response to the first signal. The base station then determines a base station timing calibration error based on the LOS delay, the first signal arrival time, and the RTD, and dynamically calibrates the base station timing to compensate for the base station timing calibration error.

摘要： Method and apparatus for scheduling transmissions in a wireless communication system using historical information and usage patterns of remote users in the system. Usage patterns for users within a system are stored and analyzed to optimize transmissions and resources in the system. In one embodiment, the user patterns are used to predict travel routes and transmissions scheduled accordingly. In another embodiment, the system is an ad-hoc system or a hybrid system, wherein the usage patterns are used to determine the source-to-destination paths.

摘要： A method of and system for calibrating a repeater in a wireless communications system are provided. The one or more calibration parameters for the repeater are derived from (a) time measurements derived from one or more signals relayed by the repeater and received at a plurality of different measurement positions, and (b) the positions of the measurement locations. In one application, the one or more parameters are used in determining the positions of subscriber stations in the wireless communications system.

摘要： A method and apparatus for tracking the position of a mobile unit in a mobile radio communication system using information from earth-orbiting satellites and information received from the infrastructure of the system, wherein the infrastructure consists of equipment associated with transmitting and receiving voice or data traffic to and from the mobile phone. An initial position of the mobile unit is calculated using measurements from earth-orbiting satellites. Next, one or more range measurements are made using signals transmitted between the mobile unit and the infrastructure. A positional difference between the initial position and a current position of the mobile station is estimated using the one or more range measurements, wherein only range measurements made from signals transmitted between the mobile unit and the infrastructure are used to perform the estimating. An accuracy value is next determined for the estimated positional measurement, and the accuracy value is compared to a threshold to determine whether the estimated positional measurement has an acceptable accuracy. If the estimated positional measurement has an acceptable accuracy, then the initial position of the mobile unit is updated using the estimated positional measurement and the process is repeated using only range measurements made from signals transmitted between the mobile unit and the infrastructure; otherwise, a new initial position is determined from the earth-orbiting satellites and the process is repeated.

摘要： A method and apparatus for determining the position of a wireless communication device using global positioning system (GPS) satellites, base stations synchronized to GPS time and base stations that are unsynchronized with GPS time. The unsynchronized base stations are synchronized with one another. Time of arrival information is adjusted to take into account the fact that wireless communication devices that received GPS time information from a base station receive that information biased by the one-way delay that is encountered by the signal that communicates that information to the wireless communication device. In addition, time difference of arrival information for base stations that are not synchronized to GPS time allows the bias between these base stations GPS time to be eliminated.
