Mobile wireless terminals, such as vehicles in traffic, can determine the relative positions of other vehicles with improved precision by arranging to acquire GNSS (global navigational satellite system) signals simultaneously, and then analyzing the various data sets differentially. Simultaneous acquisition can cancel many important errors such as motional errors of the vehicles, atmospheric distortions, and satellite timebase errors. Differential analysis to determine the relative positions of vehicles (as opposed to their overall geographical coordinates) can reduce errors related to satellite ephemeris and velocity, as well as roundoff errors. Localization with a precision of less than 1 meter can greatly improve collision avoidance while discriminating near-miss scenarios from imminent collisions, according to some embodiments. Messaging examples, in 5G and 6G, to manage the simultaneous acquisition and differential analysis, are provided in examples. Many other aspects are disclosed.

A system for determining the location of a wireless device is described, the system includes a map, a fixed beacon, a fixed sensor and a server component. The server component receives a beacon identifier and a beacon signal strength from a wireless device. A sensor is located on the map. The fixed sensor receives the beacon identifier and the sensor captures a measured sensor beacon signal strength. The sensor is communicatively coupled to the server component. The server component receives the beacon identifier and the measured sensor beacon signal strength from the fixed sensor. The server component uses the beacon identifier and the beacon signal strength communicated by the wireless device and the sensor beacon signal strength and the beacon identifier received by the sensor to determine the location of the wireless device.

A first client station receives from an access point an indication of whether angular information is to be included in feedback information in a range measurement session. The first client station transmits a null data packet (NDP) as part of an uplink multi-user (MU) PHY transmission that also includes simultaneous transmissions by one or more second client stations of one or more other respective NDPs to the access point as part of the range measurement session. The first client station receives a downlink physical layer (PHY) data unit from the access point that includes respective downlink feedback frames for the first client station and the one or more second client stations. When angular information is to be included in the feedback, a downlink feedback frame for the first client station includes angular information.

A surveying system for a construction site has a restricted antenna system with a plurality of fixed location antennas each defined by a set of location data associated with a specific deployment position. The surveying system also has a computing device with a data processor and a display screen. A communications module establishes a data transfer link with the restricted antenna system over which spatial data for distances between current positions of the computing device and one or more of the plurality of fixed location antennas are received. The computing device is loadable with project drawings corresponding to the construction site and displayable on the display screen. A position marker is overlaid on the display of the project drawing at a position thereon corresponding to a computing device location value derived from the spatial data and the location data of one or more of the fixed location antennas.

A method and an apparatus for performing positioning by a user equipment (UE) in a wireless communication system supporting a sidelink according to various embodiments are disclosed. Disclosed are a method and an apparatus therefor, the method comprising the steps of: receiving a plurality of pieces of sidelink control information (SCI) including scheduling information of a PRS from a plurality of anchor nodes; receiving a plurality of PRSs on the basis of the plurality of pieces of SCI; on the basis of the positional relationship of the plurality of anchor nodes, detecting ambiguity in position measurement based on the plurality of PRSs; requesting an angle of arrival (AoA) report from one anchor node among the plurality of anchor nodes on the basis of the detected ambiguity in position measurement; and measuring the position of the UE on the basis of the plurality of PRSs and the reported AoA.

A positioning system and a calibration method of an objection location are provided. The calibration method includes the following. Roadside location information of a roadside unit (RSU) is obtained. Object location information of one or more objects is obtained. The object location information is based on a satellite positioning system. An image identification result of the object or the RSU is determined according to images of one or more image capturing devices. The object location information of the object is calibrated according to the roadside location information and the image identification result. Accordingly, the accuracy of the location estimation may be improved.

A method for position determining includes: sending a first ranging request to a base station, wherein the first ranging request carries an identifier associated with a second UE, in which the first ranging request is at least associated with ranging between the base station and the second UE; and receiving first range information associated with the first range request from the base station.

A method and system for finding the true geolocation coordinates of User Equipment (UE) using a communication network and system based on Non-Terrestrial Network (NTN). The system uses precision clock signals of a UE and satellites in an NTN. Using the time of arrival method disclosed in the invention, a trusted satellite can compute the location of a UE by processing positioning signals. Consequently, satellites accurately compute the true location of UE and store it on satellites in the space and/or database server connected with the ground station. The invention enables accurate delivery of shipments in a logistic network.

A method performed by a UE (102) that is being served by at least a first cell. The method includes the UE performing a multi round-trip-time, multi-RTT, positioning measurement (e.g., a UE Rx-Tx measurement), wherein the UE is configured with SRS for the measurement with respect to a second cell. The method also includes the UE detecting a need to change a serving cell. The method further includes, as a result of detecting the need to change a serving cell, the UE deciding whether to restart or continue performing the multi-RTT measurement. The UE is configured such that the UE continues the multi-RTT measurement if the serving cell change is for a cell different than the second cell in which the UE is configured with the SRS for the measurement.)

A vehicle navigation system includes a camera and a controller. The camera is configured to render an image of a host-vehicle in a field-of-view of the camera. The camera located remote from the host-vehicle. The controller is installed on the host-vehicle. The controller is configured to receive the image and determine a vehicle-coordinate of the host-vehicle in accordance with a position of the host-vehicle in the image. The camera may be configured to superimpose gridlines on the image, and the controller may be configured to determine the position in accordance with the gridlines.
