A system and method for proximity determination can include receiving an RF signal transmitted from a target location, the receiving performed by an antenna of an autonomous moving device, extracting received signal strength indicator (RSSI) values by processing the received RF signal, receiving distance measurements provided by a sensor associated with the autonomous moving device and storing the distance measurements in the memory of the autonomous device. The extracted RSSI values can be correlated the with the distance measurements to obtain a proximity value. A distance to the target location can be determined based on the proximity values.

A method and system are disclosed for a network node or wireless device (WD) to communicate with another WD or network node. The node or WD is configured to perform at least one timing measurement over a measurement period (T1) on signals transmitted between the node or WD and another node or WD and, during T1, determine if there is any change in a fixed time offset (FTO) used by the nodes for transmitting a reference signal. If there is a change in the FTO over T1, the network nodes or WDs are configured to perform an operational task and, if not, continue performing the timing measurement over T1. The operational tasks may include discarding the timing measurement, restarting the timing measurement, extending the measurement time, informing another node about a change in the FTO or informing another node about an action taken by the network node or WD.

Provided in a vehicle are: an external communications unit provided outside the compartment of the vehicle; and an internal communications unit provided inside the vehicle compartment. A position determination system includes a data acquisition unit that obtains reception signal strength data for radio waves that have been communicated and measured, between the external communications unit and a terminal and between the internal communications unit and the terminal. The position determination system also includes a position determination unit that determines whether the terminal is positioned outside or inside the vehicle, from the results of comparison between the size of data obtained from communication between the external communications unit and the terminal and between the internal communications unit and the terminal. In addition, the external communications unit is disposed inside a body component located around a rear wheel of the vehicle.

A system and method for one-way ranging is disclosed. The system comprises a transmitter, also referred to as tag, transmitting a packet having a first frequency. The receiver, also referred to as the locator, receives the first frequency and measures the phase at a specific point in time. At a predetermined time, the transmitter switches to a second frequency. This is performed while maintaining phase continuity. The receiver also switches to the second frequency at nearly the same time. The receiver then measures the phase of the second frequency at a second point in time. Based on these two phase measurements, the distance between the transmitter and the receiver may be calculated.

Determining when an estimated altitude of a mobile device can be used for calibration or location determination. Particular systems and methods determine an area in which the mobile device is expected to reside, determine an altitude value of each section of a plurality of sections in the area, determine if the altitude values meet a threshold condition, and determine that the estimated altitude of the mobile device can be used for determining the position of the mobile device or for calibrating a pressure sensor of the mobile device when the altitude values meet the threshold condition.

The positioning system includes a plurality of permanently installed anchor nodes that represent reference points in a common coordinate system. The positioning system is configured to determine a distance from a first anchor node to a second anchor node.

A method for maintaining timing accuracy in a mobile device includes: obtaining a range estimate using a signal received from a timing information source via a communication unit of the mobile device; obtaining position and velocity estimate information for the mobile device from a source of position and velocity information separate from the timing information source, the position and velocity estimate information being obtained from at least one sensor of the mobile device, or via a communication unit of the mobile device using a Vehicle-to-Everything wireless communication protocol, or a combination thereof; determining estimated clock parameters based on the position and velocity estimate information and the range estimate; and adjusting a clock of the mobile device based on the estimated clock parameters in response to a position-and-velocity-assisted timing uncertainty corresponding to the estimated clock parameters being below a timing uncertainty threshold.

Procedures are disclosed to enable a wireless device to determine its alignment direction toward a base station or another device in 5G or 6G, using a “phased beam-alignment pulse”, which is a transmitted pulse having phase modulation that varies with angle. For example, the pulse may be transmitted spanning 360 degrees of angle, and may be phase modulated varying from 0 to 360 degrees of phase in the same angular range. A user device can receive the phased beam-alignment pulse and immediately determine, from the phase, the alignment angle toward the transmitter. In another embodiment, the transmitter transmits a uniform, non-directional pulse, and the receiver receives it using an antenna configured to impose an angle-dependent phase shift, thereby indicating the alignment direction. With either method, wireless entities can align their beams rapidly and efficiently, using just one or two resource elements, without complex encoding or time-consuming handshaking.
