Abstract: Various solutions for an artificial intelligence/machine learning (AI/ML) positioning model using relative time input with respect to an apparatus in mobile communications are described. The apparatus may measure a first channel delay profile with a first path timing according to a first reference signal associated with a first network node. The apparatus may adjust the first path timing by a timing difference associated with a reference network node. The apparatus may: (1) generate a model output by a positioning model based on the first channel delay profile with the adjusted first path timing used as model inputs; or (2) report the first channel delay profile with the adjusted first path timing to a network.

The method includes the WTRU receiving, a first positioning reference signal (PRS) resource with parameters characterizing the first PRS and determining the suitability of the first PRS resource for use by the WTRU. The method also includes measuring the phase difference of arrival (PDOA) for available frequency pairs and generating a range estimate based on the PDOA measurement. Further, the method includes the WTRU evaluating a reliability of the PDOA measurement and an accuracy of the range estimate and, on a condition that a sufficient accuracy has been achieved, reporting the range estimate.

Abstract: The present disclosure provides a method of perceiving a position and pose of a hydraulic support group based on multi-point ranging and belongs to the field of test or measurement technologies unlisted in other categories. The method uses a hydraulic support group. The hydraulic support group includes multiple juxtaposed hydraulic supports. The method includes: with a plane above a base as a reference plane, establishing a reference coordinate system; perceiving a relative position of the base and a canopy of the hydraulic supports and perceiving a position and pose of a single hydraulic support; when the hydraulic supports have axial offset and roll phenomenon, performing offset amount calculation; based on the perception of the position and pose of single hydraulic supports, performing perception on the position and pose of the hydraulic support group. In the present disclosure, the measurement devices achieve conversion of pure distance information into three-dimensional pose information of an object in time and space by using logical combination of several real-time ranging terminals, leading to simple structure; there is no interference between measurement devices, and there is wireless connection between a signal transmitting device and a signal receiving device, resulting in no rendezvous point and being free from impact of frictional force.

Abstract: Provided is a chip-level positioning method for orthopedic surgery navigation based on an Ultra-wide Bandwidth (UWB). A UWB chip-level wireless positioning module is installed on a surgical instrument. The biggest advantage of the UWB wireless positioning module is that the UWB wireless positioning module has a wide bandwidth, so it has good anti-interference ability. In a positioning and tracking stage, only a base station and modules need to communicate to acquire spatial position of the surgical instruments relative to patients. The wireless positioning technology based on the UWB is very mature at this stage, and there are diverse intraoperative visualization means, and surgical status can be monitored through devices such as mobile phones and tablets. Compared with an existing optical positioning system, the present disclosure has the advantages of good robustness, high cost performance, strong real-time performance and the like.

Abstract: Multiple methods for determining a location of a STA operating on a mesh wireless network are described herein. A STA finder is used to monitor changes in received signal strength at each access point of a group of access points operating the mesh wireless network. The changes in received signal strength are then utilized to determine a location of STAs operating on the mesh wireless network. Methods for identifying poor performance areas on the mesh wireless network using the position information and then providing recommendations for improving the performance of the mesh wireless network are also described herein.

Abstract: A system and method for ranging secured by feedback of one or more channel metrics. The method may include: receiving, by a first modem, a first training signal, from a second modem; generating, by the first modem, a first estimate of a channel metric, based on the first training signal; receiving, by the first modem, from the second modem, a second estimate of the channel metric; determining, by the first modem, that the first estimate of the channel metric and the second estimate of the channel metric do not meet a similarity criterion; and denying, by the first modem, access to a resource.

Abstract: A method for activating a vehicle function, by an activation device including a transceiver to communicate with “hands-free” access equipment. The transceiver is equipped with a gyroscope and a magnetometer and two receiving antennas that have a coefficient of electromagnetic coupling between them that is below a threshold. The method includes the following steps for at least two consecutive footsteps: transmission of a signal comprising data of the gyroscope and the magnetometer of the “hands-free” equipment to the vehicle; comparison of the data with representative values of the gyroscope and the magnetometer of the transceiver; determination of a first direction of the user; determination of a second direction of the user based on an estimation of a first angle of arrival of the signal towards the transceiver; comparison of the first direction and the second direction; activation of the vehicle function on the basis of the result of the comparison.
