A positioning control method includes: determining a position of a positioning object; determining, based on the position of the positioning object, at least one target positioning beacon whose distance to the positioning object satisfies a predetermined condition; and sending a prompt message to the target positioning beacon, wherein the prompt message is intended to instruct a positioning beacon to switch a broadcast frequency from a first frequency to a second frequency which is greater than the first frequency.

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.

An example computer-implemented method includes compressing at least a first portion of geo-location information attributed to at least a portion of one or more access points; converting at least a second portion of geo-location information attributed to the at least a portion of the one or more access points to one or more polar coordinates; converting the one or more polar coordinates attributed thereto to at least one position on a data structure configured to have one or more predetermined properties; generating at least one compressed access point geo-location data output comprising the compressed at least first portion of geo-location information and the at least one position on the data structure; and outputting the at least one compressed access point geo-location data output to at least one user device.

A method and apparatus a first network entity in a wireless communication system supporting ranging capability is provided. The method and apparatus comprises: identifying, in a ranging block, one or more ranging rounds to transmit a ranging control message (RCM) with a multiple message receipt confirmation request (MMRCR) for a transmission of at least one first message comprising at least one of a set of ranging messages or a set of ranging ancillary data messages; transmitting, to a second network entity, the RCM with the MMRCR; transmitting, to the second network entity, ranging ancillary data in at least one ranging round of one or more ranging rounds following the RCM, wherein the ranging ancillary data is associated with the MMRCR; and receiving, from the second network entity, a ranging multiple message receipt confirmation (RMMRC) corresponding to the transmission of the at least one first message.

Systems, apparatus, articles of manufacture, and methods are disclosed for distributed and scalable high performance location and positioning. Disclosed example apparatus are to enqueue a data pointer associated with sounding reference signal (SRS) measurement data from a device into a first data queue associated with a first worker core. Disclosed example apparatus are also to generate, with the first worker core, at least one of a reception angle measurement dataset or a time-of-arrival measurement dataset based on the SRS measurement data and dequeue the data pointer associated with the at least one of the reception angle measurement dataset or the time-of-arrival measurement dataset from the first data queue into a second data queue associated with a second worker core. Disclosed example apparatus are further to determine, with the second worker core, a location of the device based on the at least one of the reception angle or time-of-arrival measurement dataset.

Embodiments of the present disclosure relate to methods and apparatuses for sidelink (SL) positioning. According to an embodiment of the present disclosure, a first user equipment (UE) may include: a receiver configured to receive SL positioning configuration information from a second UE, wherein the first UE helps the second UE to acquire its position; a transmitter configured to transmit a location information report to the second UE based on the positioning configuration information; and a processor coupled to the receiver and the transmitter.

The present application discloses a signal transmission method and a device, for achieving PRS transmission supporting different bandwidths and numerology. The embodiment of the present application provides a signal transmission method, the method includes: receiving and measuring a cell-level cell-specific first positioning reference signal PRS in a cell public measurement window, to obtain a first positioning measurement value, and applying to the network side for a terminal-level UE-specific second PRS resource in a non-cell public measurement window based on the first positioning measurement value; receiving and measuring the UE-specific second PRS in the non-cell public measurement window, to obtain a second positioning measurement value; determining and reporting a third positioning measurement value based on the first positioning measurement value and the second positioning measurement value.

Co-channel beacon transmissions are provided with at least one of spectral redundancy and temporal redundancy. A receiver produces a snapshot of a superposition of received co-channel beacon transmissions. Subcarrier demodulation, code nulling, or a Class-C linear minimum-mean-square error (MMSE) operation separates multiples ones of the co-channel beacon transmissions or eliminates inter-symbol interference and inter-subcarrier interference in the snapshot. Receiver operations can be performed at a network user, a network node, or a network operations center.

Geolocating one or more emitters includes obtaining a set of lines of bearing (LOBs) indicative of location(s) of emitter(s), determining intersections of LOBs of the set and generating clusters informed by those intersections, assigning the LOBs of the set to cluster(s) based on proximity, identifying a cluster having the greatest number of assigned LOBs from the set; determining an emitter location area based on a best point estimate for the cluster, and indicating a location of an emitter as the emitter location area. Additional emitters can be located by removing from the set of LOBs those LOBs assigned to the identified cluster, and repeating aforementioned aspects. Initially, the set of LOBs can be selected from a larger collection as a representative subset thereof.

Tracking devices can be associated with safe zones, smart zones, and high risk zones. Safe zones correspond to regions where a likelihood that a tracking device is lost within the safe zone is lower than outside the safe zone. High risk zones correspond to regions where a likelihood that a tracking device is lost within the high risk zone is higher than outside the high risk zone. Smart zones correspond to an expected tracking device, mobile device, or user behavior. Home areas are geographic regions in which a user resides, and travel areas are geographic regions in which a user does not reside. A tracking device can be configured to operate in a mode selected based on a presence of the tracking device within a safe zone, a smart zone, a high risk zone, a home area, or a travel area.
