A method may include generating a receive timing error group (Rx TEG) based on a time delay of a receive (Rx) signal, wherein the time delay is a time measured from an arrival of the Rx signal at a Rx antenna to a time of the Rx signal being digitized and time-stamped at a baseband processor of a user equipment (UE), determining a timing error group (TEG) index corresponding to the generated Rx TEG, determining a positioning measurement associated with the Rx antenna used to generate the Rx TEG, and reporting the positioning measurement associated with the Rx TEG index.

Embodiments provided herein are directed to an ultra-wide broadband system configured to produce positioning estimates for a user device. To ensure the high quality of this positioning service, the ultra-wide broadband system is configured to prevent signal collision, and eliminate the need for inconvenient cable connections for base station deployment. Further, the one way communication nature of the ultra-wide broadband system enables low power operation of the user device.

An electronic monitoring device for monitoring at least one radionavigation signal during an approach phase to a landing runway, related monitoring method and computer program are disclosed. In one aspect, the each radionavigation signal is obtained from a reception chain on board an aircraft. The device includes a calculation module configured to calculate an angular displacement value in a reference plane, a comparison module configured to compare the angular displacement value with the corresponding radionavigation signal, and a warning module to generate a warning signal based on the comparison between the angular displacement value and the corresponding radionavigation signal. The calculation module is configured to calculate the angular displacement value as a function of a magnitude relating to the aircraft course and glide path according to the monitored radionavigation signal, from avionics equipment independent from the reception chain.

A system and method for using wireless location of mobile communication units for identifying and allocating resources for access by users of such mobile communication units via bringing the user and such a resource together. Such a user may be routed to such a resource even though the resource cannot be reserved for user access. A resource allocation priority between users mitigates a user not being able to access the user's allocated resource, e.g., due to another user accessing the resource. The resources can be, e.g., a parking space, public transportation (e.g., bus, train, taxi), seating at an open admission event, accessing a theme park ride, and the like. By wirelessly locating the user's mobile communication unit, the user may be navigated to such a user allocated resource.

A method is disclosed. In various examples, the method may include receiving an instruction for generating a signal comprising a ranging signal and a data signal. The method may also include transmitting, via a terrestrial transmitter for transmitting radio waves having encoded messaging information and timing information for one or more of positioning, navigation and timing, the signal at least partially responsive to the instruction. The signal may include a pulse group comprising a number of ranging pulses and a number of data pulses subsequent to the number of ranging pulses. Respective ones of the number of data pulses may have a phase of either a positive-going phase or a negative-going phase. Information may be encoded using the either positive-going phases or negative-going phases of the data pulses.

A location system and applications therefor is disclosed for wireless telecommunication infrastructures. The system is an end-to-end solution having one or more location systems for outputting requested locations of handsets or mobile stations (MS) based on, e.g., CDMA, GSM, GPRS, TDMA or WIFI communication standards, for processing both local mobile station location requests and more global mobile station location requests via, e.g., Internet communication between a distributed network of location systems. The following applications may be enabled by the location system: 911 emergency calls, tracking, navigation, people and animal location including applications for confinement to and exclusion from certain areas, friend finder applications, and applications for allocating user desired resources based on the user's location.

Aspects of the present disclosure may compensate for a presence of phase ambiguity between transmit chains of a transmitting device when estimating angle of departure information of a wireless signal transmitted from the transmitting device. In some aspects, a receiving device may determine phase information of the wireless signal, and then determine whether there is a presence or absence of phase ambiguity between a number of transmit chains of the transmitting device. If there is presence of phase ambiguity in the transmitting device, then the receiving device may adjust the phase information of the received wireless signal. If there is an absence of phase ambiguity in the transmitting device, then the receiving device may not adjust the phase information. Thereafter, the receiving device may estimate the angle of departure of the wireless signal based on the selectively adjusted phase information.

A framework for identifying parking areas from vehicle trajectory data is described herein. Vehicle trajectory data collected from a sensor network having a plurality of sensor stations for detecting vehicles is provided. The vehicle trajectory data is pre-processed to generate a tracking table of vehicles and analyzed to determine an interstation parking area between first and second sensor stations of interest based on input parameters from a user.
