Localization systems and methods for transmitting timestampable localization signals from anchors according to one or more transmission schedules. The transmission schedules may be generated and updated to achieve desired positioning performance. For example, one or more anchors may transmit localization signals at a different rate than other anchors, the anchor transmission order can be changed, and the signals can partially overlap. In addition, different transmission parameters may be used to transmit two localization signals at the same time without interference. A self-localizing apparatus is able to receive the localization signals and determine its position. The self-localizing apparatus may have a configurable receiver that can select to receive one of multiple available localization signals. The self-localizing apparatuses may have a pair of receivers able to receive two localization signals at the same time. A bridge anchor may be provided to enable a self-localizing apparatus to seamlessly transition between two localization systems.

A method for positioning reference signal configuration comprises receiving, from a network node, one or more first positioning reference signals in a first PRS configuration; performing one or more first measurements on the first PRS to determine one or more first characteristics of the one or more first PRSs; sending, to the network node, a second PRS configuration determined based on the one or more first characteristics; receiving, from the network node, a third PRS configuration, wherein the third PRS configuration comprises one or more third PRSs having at least one different signal characteristic than the one or more first characteristics of the first PRS; and performing one or more second measurements on the one or more third PRSs. The method provides a dynamic configuration for PRS based on the feedback from the UE and a location node, beamforming configuration, or any requirements for physical layer efficiently.

A system for assisting the positioning, in particular the orientation, with regard to a target position, of an antenna of a beacon intended to be in communication link by radio signal with a transmitter/receiver device, the system including a system for representation of a lobe of the radiation pattern of the antenna of the beacon on a projection surface of an environment in which said beacon is intended to be installed, and a system for measuring a distance separating the beacon and at least one point on the projection surface corresponding to the target position or positions.

Disclosed herein are an apparatus and method for providing crosswalk pedestrian guidance based on an image and a beacon. The method for providing crosswalk pedestrian guidance based on an image and a beacon may include estimating a walking location based on a beacon signal corresponding to at least one traffic light and first-person view sensor information, analyzing a hazard factor around a pedestrian based on an image acquired from a camera corresponding to the traffic light, predicting a hazard around the pedestrian in combination by considering together the walking location, the hazard factor, and status information of the traffic light, and providing walking guidance to a pedestrian guidance terminal based on the predicted hazard around the pedestrian.

A ranging beacon system to measure the performance of a running athlete can include a ranging base and a wearable device. The ranging base can be placed along an exercise path with line of sight to an athlete and can include a ranging base ultra-wideband (UWB) transceiver. The ranging base UWB transceiver can receive a first UWB signal and transmit a second UWB signal. The wearable device can be worn by the athlete and the wearable device can include a wearable device UWB transceiver, and a processor. The wearable device UWB transceiver can transmit the first UWB signal and receive the second UWB signal. The processor can generate ranging data of the athlete based on the first and the second UWB signals.

A system comprising a vehicle and a server. The vehicle includes a first control unit configured to, when detecting a beacon from a beacon transmitter disposed on a road, notify the server that the beacon has been detected in response to the engine of the vehicle being stopped. The server includes a second control unit configured to, in response to receiving a notification that a beacon has been detected from the vehicle, determine whether the vehicle has passed a predetermined point, and in response to determining that the vehicle has passed the predetermined point, notify an administrator of the vehicle that the vehicle has passed the predetermined point.

A controller is configured or programmed to cause a first memory to store, for a period of time, piece(s) of identification information included in wireless signal(s) transmitted from transmitter(s) in or on attachment(s) and received by a receiver in or on a working vehicle, when one of the attachment(s) is attached to a hitch, select a piece of identification information of the attachment attached to the hitch from the piece(s) of identification information stored in the first memory and start a predetermined process according to the selected piece of identification information, and even if the receiver receives wireless signal(s) before the attachment is allowed to be detached from the hitch, continue to perform the predetermined process without performing selection of a piece of identification information again.

There is described an interior positioning system for tracking spatial position of communication devices within a remote location. The interior positioning system generally has: a radio frequency network distributed through said remote location; beacons spaced-apart from one another throughout said remote location and powered by said radio frequency network, each beacon locally emitting a corresponding beacon identifier which when received by a nearby communication device is communicated over said radio frequency network by said communication device; and a tracking controller being communicatively coupled to said radio frequency network, said tracking controller stored thereon tracking data associating each of said beacon identifiers to respective spatial coordinates, and instructions that when executed perform the steps of: receiving said beacon identifier communicated over said radio frequency network by said communication device, and determining spatial coordinates of said communication device by cross referencing said received beacon identifier to said tracking data.

Systems and methods for configuring groupings of wireless devices and performing positioning and/or ranging between the grouped devices. Several wireless devices can be grouped together according to location, capabilities and/or measurements. A master node can be assigned to perform initiate a sidelink ranging procedure for the group. The master node can transmit ranging request(s) and receive ranging response(s) to calculate a range for one or more wireless devices in the group.

The following generally relates to using Augmented Reality (AR) to enhance the in-vehicle experience. In some examples, AR techniques are applied to provide AR indications of vehicle safety indicia to alert vehicle occupants to information that may not otherwise be perceptible. In other examples, AR techniques are applied to provide emergency vehicle warnings to improve the likelihood of safe responses thereto. In yet other examples, AR techniques are applied to generated personalized outdoor displays, for example, to ameliorate conditions that may impair safe operation of a vehicle.
