Positioning of one or more user equipments (UEs) is performed using broadcast common sounding reference signals (SRS) resources for positioning. The common SRS that is broadcast by a UE is received and measured by one or more base stations and one or more other UEs. The other UEs may have known positions and may server as anchor nodes for positioning. The other UEs may have known positions and may serve as a positioning (anchor) node or may have unknown positions and may be jointly positioned with the target UE. During joint positioning, each of the other UEs may similarly broadcast a common set of SRS that is received and measured by the base stations and other UEs for positioning. An angular measurement of the SRS broadcast by one or more UEs may be measured and used to resolve mirror symmetry in positioning solutions.

An exemplary computing system for locating an object in an operational area is disclosed. The computing system having a server and plurality of edge devices. The edge devices having an image sensor configured to capture video data of the operational area from a specified location. The edge devices can process the video data to identify an object and generate a two-dimensional shape representative of the object, generate a vector from a lens of the image sensor through a center point of the two-dimensional shape; and determine relative position of the two-dimensional shape based on geospatial information of the edge device and the vector. The server and one or more of the edge devices receiving video data from a plurality of edge devices and generating a graphic, which defines a position of the object within the operational area based on the vector and location information of each edge device.

Signalling and protocol methods are proposed to allow positioning operations with signals of the cellular system for a UE in idle or inactive mode. In one novel aspect, UL-PRS is embedded in the RACH procedure: a set of RACH preambles with the functionality of UL-PRS are defined. These preambles are sent by the UE to the serving gNB to initiate a RACH procedure, and the following signalling could convey the measurement results. In another novel aspect, positioning operations on the network side are triggered through an AMF. The AMF may elect not to bring the UE to connected mode before transferring the location request to an LMF; instead, the AMF may indicate that the UE is in idle mode and it expects to page the UE with a subsequent message from the LMF.

Systems and methods for spatial tracking using a hybrid signal are disclosed. A method for spatial tracking using a hybrid signal may include: receiving, from a peripheral unit and via an antenna array of a central unit, a signal that includes inertial measurement data from an inertial measurement unit (IMU) of the peripheral unit, and a constant tone extension (CTE); determining, based on the CTE, direction data for the peripheral unit; and determining, based on the direction data and the inertial measurement data, spatial tracking data for the peripheral unit.

This disclosure provides methods, devices, and systems for beam group reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, multiple PRS resources, e.g., a beam group, received by a user equipment (UE) from the same network entity may be used to produce a combined Time of Arrival (TOA) measurement for the reference or target to derive an Reference Signal Time Difference (RSTD) estimate. The UE provides to a network entity an indication of the PRS resources in the beam group, which may be specifically or generally identified. Additionally, parameters associated with the beam group are provided, such as a relative quality of the TOA measurement for each PRS resource in the subset, a spread of the TOA measurements in the subset, a relative signal strength of each PRS resource in the subset, or a spread of the signal strength in the subset.

A method performed by a system (120) for determining a position of a device (140) connected to a communication network (100) is disclosed. The method comprises obtaining a geographical area for the device based on a first position-estimation service, obtaining information on luminosity on the device over a time period, and determining a second position estimation for the device (140) based on the geographical area and on the information on luminosity, by comparing the information on luminosity over the time period to a 3D model of the geographical area, the 3D model comprising models of 3D objects of the geographical area and a model of sunlight shining onto the models of the 3D objects over the time period. Disclosed is further a corresponding system and a position-determining method performed by a communication device.

An apparatus, method and computer program are disclosed. The apparatus may include circuitry configured for receiving from a target device, at a first time instance, a set of first measurement data associated with each of a plurality of base stations and determining a first position of the target device based on the received first sets of measurement data. The circuitry may also receive from the target device, at each of one or more subsequent time instances, a second set of measurement data associated with one, or each of a smaller number, of the base stations and determining, at each of the one or more subsequent time instances, a respective position of the target device based on the position determined at a previous time instance and the second set of measurement data.

A method for reporting, by a terminal, a measurement result for location determination according to an embodiment of the present disclosure comprises the steps of: determining whether a channel characteristic between the terminal and each base station included in a plurality of base stations configured for location determination of the terminal corresponds to a visible ray (line of sight: LoS); calculating a reference signal time difference (RSTD) by configuring, as a reference cell, one of the base stations, the channel characteristics of which correspond to a visible ray (LoS); and reporting a measurement result including the RSTD.

A positioning operation for a user equipment (UE) involves a two-step process having a coarse positioning followed by a refined positioning. The coarse positioning can be based on periodic reference signals from a first set of network nodes. A refined positioning specific to the UE is configured based on the coarse positioning. The refined positioning can include targeted transmissions of reference signals to the UE by a second set of network nodes.

The present disclosure is directed to a computer-assisted or autonomous driving (CA/AD) vehicle with a controller to control one or more light emitters to produce a light pattern that uniquely identify the vehicle. It may also be directed to a system to receive image data from one or more video cameras located in a location vicinity of the CA/AD vehicle emitting a pattern of light, and to analyze the received image data to determine a physical location of the vehicle.
