Disclosed are techniques for communication. In an aspect, a first network entity receives an integrated access and backhaul (IAB) node information message from a second network entity, the IAB node information message including one or more parameters for at least one transmission-reception point (TRP) of a base station, wherein the at least one TRP corresponds to an IAB node, and wherein the one or more parameters are related to the at least one TRP corresponding to the IAB node, and performs one or more positioning operations based on the one or more parameters to locate a target user equipment (UE) engaged in a positioning session with a location server.

Methods, systems and apparatuses for location monitoring are disclosed. One system includes a first location monitoring apparatus that includes a plurality of sensors, shared storage, and a low-power controller. For an embodiment, the low-power controller operates to manage the plurality of sensors, manage storage of sensed information in the shared storage, communicate with an upstream server, and communicate with a second location monitoring apparatus. For an embodiment, a high-power controller operates to retrieve at least a portion of the stored sensed information, process the at least the portion of the stored sensed information, communicate with the low-power controller, and communicate with a second low-power controller of the second location monitoring apparatus through the low-power controller. For an embodiment, the low-power controller is powered and operable for greater periods of time than the high-power controller, and where the low-power controller.

A system for recognizing the location of a subject, comprises a server, signal transceivers, and a tracking device. The server transmits a request and stores a map file. The signal transceivers respectively communicate with the server to receive the request, and broadcast a reference signal to the other signal transceivers. The tracking device bidirectionally communicates with the signal transceivers, and periodically sends a tracking signal. After each of the signal transceivers obtains the first received signal strength indicator corresponding to the received reference signal and the second received signal strength indicator corresponding to the received tracking signal, each transmits the first signal strength indicator and the second signal strength indicator to the server. The server determines relative position information for the at least one tracking device within the map file according to the first signal strength indicators, the second signal strength indicators, and location information from the signal transceivers

Methods, systems, and devices for asset travel monitoring are provided. An example method for asset travel monitoring involves monitoring a motion sensor of an asset tracking device located at an asset to determine whether the asset has entered into a travelling state, upon determination that the asset has entered into the travelling state, monitoring the motion sensor to determine whether the asset has left the travelling state, and, upon determination that the asset has left the travelling state, obtaining a present location of the asset tracking device and transmitting the present location to a remote server.

A system for providing real-time always-on location is presented for maintaining the current location of a mobile device, while saving the battery by managing the GPS in a power-saving mode while the device is considered to be stationary. The system also provides a real-time location in an indoor environment where a GPS signal may not be available. Additionally, methods for driving detection are also presented.

Disclosed is an approach for improving performance of a radio-based positioning system by detecting and excluding mobile radio nodes. The disclosed approach involves processors (e.g., of positioning server(s) and/or of a computing device) making a determination (i) that a speed of a computing device is at or above a threshold speed, and (ii) that at least one condition is met, the at least one condition indicating that a radio node is moving substantially along with the computing device. In response to making the determination, the processors may deem the radio node to be a mobile node. Given this, the processors may in turn exclude the radio node for positioning purposes, which may ultimately improve performance of the radio-based positioning system.

Calibrating an unstable sensor of a mobile device. Systems and methods for calibrating a sensor of a mobile device determine a first estimated position of the mobile device without using any measurement from the sensor of the mobile device, generate a second estimated position of the mobile device using a measurement from the sensor, estimate a sensor error of the sensor using the first estimated position and the second estimated position, and use the sensor error to determine a calibration value for adjusting one or more measurements from the sensor.

Systems and methods of using a robot to train the system for motion detection are provided. A simple robot can be put in a room and programmed not to move except in accordance with specific programmed command. Such commands may be sent to the robot regarding movement(s) at a certain rate than could be seen in the response to a channel. A data set may be built over time, where the robot may be programmed to move such that the robot does change at specific times in duration and amount. Such robot motion may also be iterated. The algorithm records the impulse response changes associated with the robot changes and a database may be built based on such recorded and associated changes.

Techniques for location source control for paired devices are described. Location source control selects a location source for a mobile device. The mobile device can receive, from an application program, a request for determining a location of the mobile device. The mobile device can determine a first location estimate using a location subsystem of the mobile device. The mobile device can determine whether to provide the first location estimate as input to the application program, or to provide a second location estimate as input to the application program. The second location estimate can be an estimated location of the companion device and determined by the companion device.
