User equipment (UE) movement state estimation based on measurements for two or more sites in a wireless network
Embodiments include methods for determining a movement state of a user equipment (UE) operating in a radio access network (RAN). Such methods include performing positioning measurements on signals received from a plurality of transmission points (TPs) in the RAN, including first measurements of Doppler shift of signals from a first TP, second measurements of Doppler shift of signals from a second TP that is spatially separated from the first TP, and third measurements of signals from a third TP. The third TP can be the same as the first or second TP, or spatially separated from both. Such methods include determining a UE movement state based on the positioning measurements and an interacting multiple-model (IMM) that includes a first almost-constant velocity model, a second maneuver velocity model, and a Doppler shift bias state common to the first and second models. Other embodiments include complementary methods for a RAN node.
Information processing method, information processing device, and non-transitory computer readable recording medium storing information processing program for specifying a location where multiple mobilities stop
A server device acquires location information indicating a location of a mobility, identification information on another mobility, the identification information being received from the other mobility by near field communication, and stop information indicating whether the mobility stops, from multiple mobilities; classifies two or more mobilities into a same mobility group, the two or more mobilities stopping and mutually receiving the identification information among the multiple mobilities; and specifies a stop place where the mobility group stops based on the location information on the two or more mobilities classified into the mobility group.
METHODS AND APPARATUS FOR USING RECEIVED SIGNAL STRENGTH INFORMATION IN A WIRELESS SYSTEM
Methods and apparatus for processing and using signals transmitted by a device, e.g., a low cost beacon transmitter device, to facilitate making location determinations with regard to the transmitting device and/or making a decision of when or how to use location information generated based on received signals are described. In accordance with some features the processing performed on the received signal strength measurements is based on whether or not the device from which the signals are received is in motion. The size of a sample period used as a processing window when determining device location is based, in some embodiments, on the rate of motion. When and/or how to use location determinations are performed is also based on motion in some embodiments. Machine learning updates of location determination parameters, based on received signals, are disabled when the signals are from devices determined to be in motion.

SMART MANUFACTURING SYSTEMS AND METHODS FOR REAL-TIME TRACKING AND VALIDATION OF MANUAL ASSEMBLY TASKS
A method of operating a smart manufacturing system includes a beacon device borne by a user's appendage broadcasting beacon signals indicative of the appendage's location during assembly of a part within a manufacturing facility. A network of radio-frequency transceivers located within the manufacturing facility receives the beacon signals; a system controller uses the beacon signals to derive an appendage path with a stop location and stop time of the appendage when performing a manual task during part assembly. The controller retrieves a part-specific build plan that contains a predefined stop location and stop time for assembling the part. The controller detects a task error when the task's stop location differs from the predefined stop location and/or the task's stop time differs from the predefined stop time. Responsive to the detected error, the controller commands a system component to output an audible, visual, and/or tactile alert indicative of the task error.
