Abstract: A system and method for determining a position or a movable device is disclosed. The present system utilizes a movable device equipped with a locator device that has an antenna array such that it may determine the angle of arrival of a plurality of incoming beacon signals. In certain embodiments, the movable device is also able to measure its distance travelled. By knowing its distance moved and the angle of arrival from each beacon, the locator device is able to calculate its position as well as the position of each beacon. This procedure may be executed at regular intervals so that the movable device accurately determines its position.

Abstract: Aspects presented herein may enable a network node (e.g., a UE, a TRP/base station) to provide its beam squint information and/or to receive beam squint information of another positioning entity to improve the accuracy and reliability of UE positioning. In one aspect, a network node obtains beam squint information associated with a set of beams of the network node under a plurality of center frequencies. The network node transmits, for a network entity, the beam squint information for at least one beam of the set of beams for a positioning session. The network entity participates, based on the beam squint information via the at least one beam, in the positioning session with the network entity.

Abstract: A terminal interaction method includes establishing, by a first terminal, a connection to at least one second terminal using a BLUETOOTH component, and obtaining location information of the second terminal; when the first terminal points to a direction of a second terminal, identifying, by the first terminal, the second terminal based on the location information and the direction to which the first terminal currently points; and when the first terminal performs a first action, sending, by the first terminal, a first message to the second terminal based on the first action, where the first message indicates the second terminal to perform a first function, and the first function is in a one-to-one correspondence with the first action.

Abstract: System for detecting a person on an underground, which is provided with passive RFID tags (1) in a predetermined pattern, while the person is provided with a sensor module (2), which is adapted to determine the position thereof relative with respect of to the RFID tags and, preferably, the direction and/or the acceleration and/or the inclination thereof. The sensor module and/or further processing means are arranged to calculate the position of the sensor module by means of triangulation calculation. The tag pattern is formed by a regular pattern of tag clusters (4), each being formed by two tag strips, oriented in a T-shape with respect to each other. Of the T-shaped clusters, the first tag strip has an even identification code and the other tag strip has an odd Identification code. The RFID tags are applied to construction foil, which is positioned under the top layer of a floor.

Abstract: A system and method for determining the orientation of a linear array of radio receivers in space is provided. The system includes a primary radio receiver and a plurality of secondary radio receivers arranged in a collinear configuration and irregularly spaced apart from one another. The primary radio receiver and plurality of auxiliary radio receivers capable of receiving radio signals from a plurality of transmitters located in known, surveyed locations in a coordinate system. With the location of the primary receiver determined, the direction in which the aligned radio devices is pointed relative to the transmitters is then determined by using the phase angle of arrival (AoA) data from each transmitter.

Abstract: An apparatus for localizing a target user equipment (“UE”) sidelink (“SL”) positioning includes a processor configured to cause the target UE to receive from a sidelink configuration source SL positioning reference signals (“SL PRS”) assistance data associated with SL reference signal transmissions e.g., beam transmissions, transmitted from one or more SL signal transmitting devices. The target UE receives transmitted SL signal information from the one or more SL signal transmitting devices and performs SL signal angle of arrival (“AoA”) measurements or SL reference signal received power (“SL RSRP”) measurements for deriving angle of departure (“AoD”) mapped to the received SL RSRP measurements or performs SL radio resource management measurements (“SL-RMM”) for determining an estimated location of the target UE using SL-AoD, SL-AoA, SL-RMM positioning techniques or combinations thereof.

Abstract: A geolocationing system and method for providing awareness in a multi-space environment, such as a hospitality environment or educational environment, are presented. In one embodiment of the geolocationing system, a vertical and horizontal array of gateway devices is provided. Each gateway device includes a gateway device identification providing an accurately-known fixed location within the multi-space environment. Each gateway device includes a wireless transceiver that receives a beacon signal from a proximate wireless-enabled personal locator device. The gateway devices, in turn, send gateway signals to a server, which determines estimated location of the wireless-enabled personal location device with angle of arrival modeling.

Abstract: A method for signal processing includes receiving via first and second antennas (34) respective first and second input signals in response to an output signal that is transmitted from a wireless transmitter (27, 28, 30) and encodes a predefined sequence of symbols. A temporal correlation function is computed over the first and second input signals with respect to one or more of the symbols in the predefined sequence so as to identify respective first and second correlation peaks and extract respective first and second carrier phases of the first and second input signals at the first and second correlation peaks. A phase difference between the first and second signals is measured based on a difference between the first and second carrier phases extracted at the first and second correlation peaks. Based on the measured phase difference, an angle of arrival of the output signal from the wireless transmitter is estimated. There is additionally provided, in accordance with an embodiment of the invention, a method for location finding, which includes receiving radio signals transmitted between a plurality of fixed transceivers having multiple antennas at different, respective first locations and a mobile transceiver at a second location. A respective phase difference is detected between the received radio signals that are associated with each of the multiple antennas of each of the fixed transceivers. Multiple loci are computed, corresponding respectively to respective angles between each of the fixed transceivers and the mobile transceiver based on the respective phase differences. Location coordinates of the mobile transceiver are found based on the angles and the transmit locations of the transmitters by identifying an intersection of the loci as the second location of the mobile transceiver.
