Devices and methods for providing a retrievable record of the times of the actual aircraft movements such as the Gate Out time when the aircraft leaves the gate or parking position, the Wheels Off time when the aircraft takes off, the Wheels On time when the aircraft touches down during landing, and the Gate In time when the aircraft arrives at the gate or parking position (OOOI times). A mobile device for logging data onboard an aircraft comprises: a motion sensor; a clock; a non-transitory tangible computer-readable storage medium for storing motion data from the motion sensor and associated time data from the clock; and a data processing system configured to identify stored motion data representing respective acceleration/deceleration vectors of the mobile device motions that correspond to aircraft gate departure and arrival and aircraft takeoff and landing. The OOOI times are automatically logged in the non-transitory tangible computer-readable storage medium.

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.

Methods and systems for determining a device position include determining a first position estimate using radio-based range information. A second position estimate is determined using visual odometry information. The first position estimate and the second position estimate are fused based on radio environmental conditions and visual environmental conditions to determine a final position estimate. Resources are deployed based on the final position estimate.

Embodiments of this application describe a motor vehicle self-driving method and a terminal device. The method may include obtaining, by a terminal device, vehicle external-environment data of a position of a motor vehicle and initial positioning precision of the motor vehicle. The method may also include determining, by the terminal device, a target driving parameter of the motor vehicle based on the vehicle external-environment data and the initial positioning precision. Furthermore, the method may include controlling, by the terminal device, the motor vehicle to drive based on the target driving parameter. In the embodiments of this application, the terminal device determines the target driving parameter of the motor vehicle based on the vehicle external-environment data and the initial positioning precision. In this way, the target driving parameter varies with the vehicle external-environment data, and further matches an external environment, thereby improving self-driving safety of the motor vehicle.

A method performed by a network node for locating a User Equipment (UE) is provided. The network node, the at least one portable network node and UE operate in a wireless communication network. The network node configures (204) the at least one portable network node to broadcast reference signals. The broadcasted reference signals trigger the UE to subsequently measure and report the quality of the respective reference signals to the network node. The network node then receives (205) subsequent measurement reports from the UE. Each measurement report comprises a current quality value of the reference signals sent by the respective at least one portable network node. The network node manages the respective at least one portable network node to approach the position of the UE by: Meanwhile analyzing the subsequent measurement reports, commanding (206) each of the at least one portable network node to move in a direction that is decided based on the analysis of its corresponding subsequent measurement reports one by one upon receiving them. The moving direction is to be performed such that quality values of its corresponding reference signals in subsequent measurement reports are increasing.

A positioning method and apparatus, a terminal device and a storage medium are provided. The method includes: receiving positioning assistance information; performing positioning measurement according to the positioning assistance information; and positioning a target terminal by using a result of the positioning measurement. By means of the solution, the positioning of a terminal device in a Vehicle to Everything (V2X) scenario can be realized.

During positioning of a user equipment (UE), downlink (DL) positioning reference signals (PRS) transmitted by one or more transmission reception point (TRP) in a wireless communication system may be preempted or punctured by higher priority transmissions, such as ultra-reliable low-latency traffic (URLLC). A PRS preemption indication (PI) may be provided to a UE by a serving TRP identifying one or more TRPs affected by preemption. The PRS PI may further identify the time domain and frequency domain of the preempted DL PRS transmissions. The PRS PI may identify the time domain, e.g., based on a number of PRS symbols between two monitoring occasions, wherein only PRS symbols that contain downlink positioning reference signals associated with the group of TRPs are counted. The PRS PI may identify the frequency domain by identifying at least one of four or more frequency sub-bands of the preempted DL PRS transmissions.

Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, on a first downlink receive beam, one or more first positioning reference signals (PRS) transmitted by a first base station on a first downlink transmit beam, attempts to receive, on the first downlink receive beam, one or more second PRS transmitted by a set of base stations, other than the first base station, on a set of downlink transmit beams other than the first downlink transmit beam, determines that one or more signal strength measurements of the one or more second PRS received on the first downlink receive beam are below a threshold, and transmits a request to update the set of downlink transmit beams or the first downlink transmit beam, or to establish a new beam pairing with the first base station, the set of base stations, or both.

Techniques are discussed herein for providing on-demand positioning reference signals (PRS) to user equipment (UE). An example method for determining a location of a user equipment according to the disclosure includes receiving a first assistance data associated with a first positioning reference signal configuration, transmitting a request to modify one or more parameters of the first positioning reference signal configuration, receiving a second assistance data associated with a second positioning reference signal configuration, wherein the second positioning reference signal configuration is based at least in part on the request to modify the one or more parameters of the first positioning reference signal configuration, obtaining measurements from one or more positioning reference signals based at least in part on the second assistance data, and determining the location based at least on part on measurements obtained from the one or more positioning reference signals.
