Some demonstrative embodiments include apparatuses, devices, systems and methods of one-sided location measurement. For example, an apparatus may include circuitry and logic configured to cause a wireless station to transmit an announcement element to announce a Non-Data Packet (NDP) sounding transmission including a plurality of sounding preambles, the announcement element including at least a measurement type field to indicate a type of a one-sided location measurement, and one or more configuration fields including configuration information to configure the one-sided location measurement based on the NDP sounding transmission; and to transmit the NDP sounding transmission subsequent to the announcement element.

An indoor positioning system and an indoor positioning method allow all of the wireless base stations and mobile terminals in the same interior space to synchronously generate their time slots. Further, each mobile terminal transmits a positioning signal only at a preset time point in each time slot to prevent collisions between mobile terminals transmitting the positioning signals.

The present invention provides a UE for performing measurement for positioning, a UE for transmitting a signal for positioning, and a positioning server and a base station for supporting positioning. The measuring UE receives configuration information relating to an uplink reference signal for positioning, receives the uplink reference signal on the basis of the configuration information and transmits information relating to a metric value measured on the basis of the uplink reference signal and information relating to a reception-transmission time difference of the measurement UE.

Disclosed are methods, devices, systems, apparatus, servers, computer-/processor-readable media, and other implementations, including an example method to facilitate position determination operations that includes receiving, at a mobile wireless device, broadcast control signals for a location transmission unit (LTU) configured for downlink-only communication, with at least some of the broadcast control signals being transmittable by a different wireless node than the LTU. The method further includes detecting the LTU, by the mobile wireless device, based on the broadcast control signals, detecting, by the mobile wireless device, upon detection of the LTU based on the broadcast control signals, one or more LTU broadcast positioning reference signals transmitted by the LTU, and determining position information for the mobile wireless device based on the one or more LTU broadcast positioning reference signals detected by mobile wireless device.

A computer broadcasts a tier 1 signal from a target device and records transmission data of the broadcast. The computer detects the tier 1 signal at nearby propagator devices and records additional transmission data before determining whether a propagation limit has been reached. Based on not reaching the propagation limit, the computer instructs the nearby propagator devices to broadcast a tier 2 signal. The computer records further transmission data at other nearby propagator devices detecting the tier 2 signal and, again, determines whether the propagation limit has been reached. Based on determining that the propagation limit has been reached, the computer filters outliers from all the transmission data and determines the precise location of the target device. Furthermore, the computer displays the relative location of the target device on one or more devices.

Described herein are techniques related to transmitter precoding for optimizing positioning performance. The techniques are directed to transmit signals with relatively higher transmission power, in a direction along the line of sight between the transmitter and the receiver, than signals transmitted in other directions. The techniques render the first signal arriving at the receiver, as it travels along the line of sight between the transmitter and the receiver, to have stronger signal strength than the signal strengths of other signals that travel through non-LoS paths to reach the receiver.

Described herein is a method of setting-up a range-based tracking system utilising a tracking coordinate system that uses a plurality of spaced apart stationary nodes for tracking objects within a tracking environment. The method includes the step of transmitting signals between the stationary nodes to obtain range information between at least a subset of pairs of the nodes and determining coordinates for all of the stationary nodes in a node coordinate system using these range information. The method also includes the step of obtaining spatial information related to at least one of the nodes, the spatial information being indicative of one or more features or locations within the tracking environment and determining the location of all stationary nodes in the tracking coordinate system, wherein some or all of the coordinates of the stationary nodes are used for tracking objects in the tracking system.

Disclosed embodiments facilitate wireless channel calibration, ranging, and direction finding, between networked devices. A method on a first station (STA) may comprise: broadcasting, at a first time, a first NDPA frame to a plurality of second STAs. The first NDPA frame may include a first bit indicating that one or more subsequent frames comprise ranging or angular information. After a Short Interval Frame Space (SIFS) time interval from the first time, a second frame may be broadcast. The second frame may be a Null Data Packet (NDP) frame. In response, a plurality of Compressed Beamforming (CBF) frames may be received at the first STA where each CBF frame may be received from a distinct corresponding second STA, and may include Channel Feedback Information field with information pertaining to communication channel between the first STA and the corresponding second STA. The communications may be encoded using Orthogonal Frequency Division Multiple Access.

Recursive constellations of Ultra-Wide Band (“UWB”) transceivers are optimized based on a desired functionality or objective. By structuring transceivers of an UWB network into a plurality of subsets or constellations of UWB nodes each constellation can be optimized for a particular purpose while maintaining connectivity and cohesiveness within the overarching network. Implementations of specific functionality can be applied to Intra-Vehicle, Inter-Vehicle and Vehicle-to-Infrastructure constellations resulting in localized optimizations while maintaining a cohesive and coherent UWB network.

A method for distributed beacon management, including: broadcasting a packet from the beacon; receiving the packet at an application executing on a plurality of user devices; and transmitting beacon information extracted from the packet to the management system from the application.
