  • Patent number: 10693511
    Abstract: Radio circuitry wirelessly serves User Equipment (UE) with dynamic direction-of-arrival reception. Control circuitry determines a primary direction-of-arrival for a user signal and configures a digital filter for the primary direction-of-arrival. Detection circuitry filters the user signal with the digital filter configured for the primary direction-of-arrival and recovers user data from the user signal. The control circuitry determines increased radio noise and/or uplink utilization reconfigures the digital filter for multiple directions-of-arrival. The detection circuitry filters a subsequent user signal with the digital filter configured for the multiple directions-of-arrival and recovers additional user data from the subsequent user signal.

  • Patent number: 10595292
    Abstract: The invention relates to an asynchronous wireless communication system, such as a UMTS system. The various base stations of an asynchronous wireless communication system do not typically have known timing offsets Tb(i), and these timing offsets vary with time. The invention allows the calculation of the difference dTb(i,j) between timing offsets Tb(i), Tb(j) for pairs of base stations B(i), B(j), using the timing of signals received by one or more wireless communication units. Having eliminated the timing offsets between the base stations as a variable, geo-location techniques from synchronous networks may then be used to locate wireless communication units in the asynchronous wireless communication system.

  • Patent number: 10587987
    Abstract: A wireless device uses a tracking system to determine locations of target devices relative to the wireless device in an environment including one or more target devices. The tracking system receives a signal transmitted by a target device in the environment and performs an angle of arrival operation to determine the angle of arrival of the received signal. The tracking system applies a filter to determine an estimation value for the target device representing a system state for the target device. The tracking system assigns the received signal and corresponding angle of arrival to a track based on the estimation value. The tracking system identifies and removes outlier signals from the track to produce a filtered set of signals. The filtered set of signals is used to compute a point-of-origin vector for the target device for use in interacting and communicating with the target device.

A second terminal is disposed in a prescribed position, measures the radio wave intensity of the radio waves from the plurality of wireless connection devices in the prescribed position, generates first reference data including information of the measured radio wave intensity, and transmits the first reference data to the position detection server through the wireless connection devices.

  • Patent number: 10299241
    Abstract: Systems and methods determine the location of user equipment (UE) in a radio access network (RAN). A network device collects UE location indications and corresponding received signal strength measurements for wireless access stations concurrently visible to cooperating UE devices at the indicated locations. Each UE location indication and corresponding received signal strength measurements provide a data point. The network device assigns signature areas having the same combination of the concurrently visible wireless access stations; identifies multiple clusters of data points in the signature areas; assigns a location value, which represents a geographic area, to each cluster of the multiple clusters; and determines an estimated location of another UE device, wherein the estimated location includes the location value of one of the multiple clusters based on concurrently visible wireless access stations and corresponding received signal strength measurements reported by the other UE device.

  • Patent number: 10263688
    Abstract: A method for vehicle communications is disclosed. The method comprises monitoring, in a vehicle during travel, line of sight (LOS) datalink messages sent to one or more other vehicles from one or more ground stations in a LOS datalink network coverage area, and calculating a rate in which the LOS datalink messages are sent to the other vehicles. The method detects that the vehicle is substantially out of the LOS datalink network coverage area, when the LOS datalink messages rate drops below a threshold value. Messages are transmitted from the vehicle over a different available network when the vehicle is substantially out of the LOS datalink network coverage area.

  • Patent number: 10230276
    Abstract: Various embodiments use prospective synchronization signals early in the signal reception to adjust framing cycles of communication nodes to reduce jitter. Some embodiments temporarily suspend messaging between existing nodes of a communication system while instructing new nodes to generate a beacon according to a beacon schedule. The system can monitor for responses from the new node and calculate a timing error. This timing error can be sent to the new node to adjust cycle framing. In some embodiments, these techniques for timing the receive (Rx) and transmission (Tx) cycles of a node (e.g., a client wireless antenna system) can be utilized such that the radio frequency (RF) energy received between RF energy cycles can be delivered directly to the node, stored in a client's battery by a wireless charging system, enhance the Rx signal opportunities, or make the integrity of the delivered Tx signal more efficient.

  • Patent number: 10231202
    Abstract: The invention relates to an asynchronous wireless communication system, such as a UMTS system. The various base stations of an asynchronous wireless communication system do not typically have known timing offsets Tb(i), and these timing offsets vary with time. The invention allows the calculation of the difference dTb(i,j) between timing offsets Tb(i), Tb(j) for pairs of base stations B(i), B(j), using the timing of signals received by one or more wireless communication units. Having eliminated the timing offsets between the base stations as a variable, geo-location techniques from synchronous networks may then be used to locate wireless communication units in the asynchronous wireless communication system.

  • Patent number: 10219237
    Abstract: A method in a user equipment for updating a timing of a first cell is provided. The timing is the arrival time of a signal sent from a base station in the first cell relative to a clock in the user equipment in a wireless communication network. The user equipment measures a timing offset for the first cell and respective one or more second cells. When a quality of the timing offset measurement of the first cell is below a first threshold, the user equipment computes a timing offset estimate for the first cell based on the measured timing offset for the respective one or more second cells. The user equipment then updates the timing of the first cell based on the computed timing offset estimate.
