In a method for determining a 3D directional vector between a sending device and a receiving device, the receiving device comprises at least two antenna arrays that each comprise a plurality of linearly arranged antenna elements that are aligned to different orientations. The method comprises receiving, with the antenna arrays, a signal sent from the sending device, sampling, based on the received signal, outputs of each antenna element of each antenna array at a plurality of time instants, determining, for each antenna array, a Propagator Direct Data Acquisition, PDDA, pseudo-spectrum by performing a 1-dimensional PDDA, 1D-PDDA, based on the sampled outputs of the respective antenna array and on a plurality of steering vectors associated with the respective antenna array, determining a maximum of each PDDA pseudo-spectrum, determining an angular quantity (Ψ) for each antenna array based on the respective maximum of the PDDA pseudo-spectrum, and determining the 3D directional vector based on the angular quantities (Ψ) of each antenna array and on the orientations of the antenna arrays.

First information is obtained from a sensing device at a first time. The first information corresponds to a radio signal received at the device from a candidate location. The device is at a first location at the first time. Second information is obtained from the device at a second time. The second information corresponds to a radio signal received at the device from the candidate location. The device is at a second location at the second time. A system determines that a pattern is in each of the first and second information and determines relationships between the candidate location and the device at each first and second location. The system obtains inverses of the relationships and determines estimates of the received radio signals based on the information and inverses. The system measures or estimates energy emitted from the candidate location based on the estimates.

This disclosure provides systems, methods and apparatuses for wireless communication that may allow a user equipment (UE) to determine its relative position and distances to other UEs more accurately than standard vehicle-to-everything (V2X) communications allow. In some implementations, a UE (or other wireless communication device) participating in a positioning operation may transmit and receive positioning signals on an unlicensed radio band, and may transmit and receive non-positioning signals on a V2X channel (or on another suitable channel) of a radio access network (RAN). The positioning signals may include positioning reference signals (PRSs) associated with observed time difference of arrival (OTDOA) positioning operations, ranging signals associated with round-trip time (RTT) positioning operations, or other suitable signals from which the position of the UE can be determined.

An Internet of Things (IoT) device, receives, from an Access Point (AP), a beacon signal including unique identifier information of the AP, which is generated based on position coordinates of each position while at least one mobile robot equipped with the AP moves; records an RSSI value, unique identifier information of the AP, and the position coordinates from each of the received beacon signals in a reception list table; selects the best three or more RSSI values in the reception list table; calculates distances to three or more APs respectively corresponding to the three or more RSSI values by using the three or more RSSI values; and estimates the position of the IoT device by using the distances to the three or more APs.

A method is disclosed, performed by a network node in a wireless communications network, for supporting positioning of a wireless device. The wireless communications network comprises a first set of radio network nodes having a first positioning reference signal configuration and a second set of radio network nodes having a second positioning reference signal configuration. The first positioning reference signal configuration provides a different positioning requirement than the second reference signal configuration. The method comprises signaling, to the wireless device, a first positioning request comprising a first indication of a positioning requirement of a first positioning measurement. The method comprises obtaining a first estimated position of the wireless device, based on a first positioning measurement for the wireless device. The first positioning measurement is associated with the first set of radio network nodes. The method comprises signaling, to the subset of the second set of radio network nodes, an indication to participate in the second positioning measurement. The second indication of the positioning requirement of the second positioning measurement indicates a different positioning requirement than the first indication of the positioning requirement.

A system and method for determining location information of a portable device relative to an object is provided. In one embodiment, aspects of the system to determine location with respect to the portable device may be distributed among more than one device in the system.

Disclosed are methods and apparatuses for resolving aliasing ambiguities produced when using channel state information reference signal, a sounding reference signal (SRS) or other transmission as a positioning reference signal (PRS) occupying a subset of tones of a PRS bandwidth. The aliasing ambiguity results in a plurality of different possible positioning measurements, such as time of arrival (TOA), reference signal timing difference (RSTD), or reception to transmission difference (Rx−Tx). The aliasing ambiguity may be resolved using a previous position estimate that may be used to produce an approximation of the expected positioning measurement. A position estimate may be generated using a multiple stage PRS configuration, in which one or more stages provide a coarse position estimate that has no ambiguity, which can be used to resolve the ambiguity of a more accurate position estimate resulting from the PRS signal.
