Partial phase vectors as network sensors
Systems and methods provide for improving the accuracy of a location system. The location system can capture partial phase vector data from one or more access points (APs). The location system can capture associated data associated with the partial phase vector data across multiple dimensions, such as identity data of the APs and client devices generating the partial phase vector data and frequency band data, location data, a time and date, and other data associated with the partial phase vector data. The location system can determine correlation data across the multiple dimensions using the first partial phase vector data and the associated data. The location system can a cause of the partial phase vector data based on the correlation data. The location system can perform one or more remediation actions based on the cause of the partial phase vector data.

Creating library of interferers
A system includes a method for detecting a signal interference in a communication signal of a wireless communication system. An identified source of the signal interference is determined according to an interference profile of a plurality of interference profiles associated with an interference profile library having information that approximates characteristics of the signal interference. The signal interference of the communication signal is mitigated according to an interference parameter associated with the identified source by filtering the communication signal according to the interference parameter.

Position estimation of a pedestrian user equipment
In an aspect, a UE (e.g., PUE or VUE) performs one or more sidelink positioning measurements on a first sidelink positioning signal between PUE and a VUE. The UE transmits measurement data based on the one or more sidelink positioning measurements to a RSU. The RSU receives the measurement data and determines a positioning estimate for the PUE. The RSU transmits the positioning estimate to the PUE, at least one VUE, or a combination thereof.
System and method of time of flight detection
A position-determining apparatus, such as a GPS receiver, determines the position of the mobile device based on the time of flight of a transmitted probe signal using a method in which sections of the received signal is classified into two or more categories and accumulated according to categories before being used to compute the correlations familiar in the context of a matched filter. Using the method of the present invention to compute the correlations, and optionally applying additional time-saving techniques described herein, a position determination is achieved using arithmetic operations that are significantly reduced from that required in prior art methods to compute the correlations. The reduced number of arithmetic operations can reduce significantly the power consumption required of a device carrying out a method of the present invention, and thereby realizing a significant advantage.
Systems and methods of live streaming emergency dispatch data to first responders
Systems, devices, and methods including: capturing, by a capture device, an audio and corresponding location metadata associated with an emergency call; refining the location metadata to provide a refined location metadata; correlating, by the capture device, the refined location metadata of the emergency call with a geofenced location of the computing devices of one or more first responders (FRs); screening, by the capture device or the computing device, the emergency call data; transmitting, by the capture device, a first signal to the one or more computing devices based on the correlation, the transmitted signal including a portion of the captured audio and corresponding location metadata; receiving, by the capture device, an accept signal from the one or more computing devices of one or more FRs; transmitting, by the capture device, a second signal to the one or more computing devices based on the received accept signal.
Geographical radio availability as a service
Some methods enable a computer to receive location information from a device and determine a coverage region for the device. The device's coverage region is the area within range of a wireless signal coming from the device. The computer can determine that part of the device's coverage region covers part of a specified region and instruct the device to provide wireless access to a network associated with the first region.
Sensor-assisted technique for RF power normalization in locationing applications
A radio frequency (RF) device includes a spatial orientation sensor and logic circuit configured to determine spatial orientation of the RF device relative to a reference position or relative to a RF transmitter. In particular, the RF device determines a distance between the RF receiver and the RF transmitter based on a received signal strength of the signal and a determined spatial orientation of the RF device, by determining an orientation compensation value from a stored orientation compensation profile and determining a resulting compensated received signal strength. The RF device is thereby able to determine distance in an orientationally-invariant manner.
Transmission power compensation by attenuation mapping in 5G and 6G
For improved messaging reliability in 5G and 6G, mobile users and their base stations can adjust their transmission power according to the current location of the mobile user. Each entity can maintain a map of known attenuation values, including “dead zones”, and can adjust their transmission power and/or reception gain to compensate. Instead of constantly exchanging location-update messages, the users can indicate their speed and direction, and the base station (or other users) can extrapolate the location versus time to determine a future location, and thereby determine the attenuation factor at the new position. In addition, the base station can use a map to follow the mobile user device's progress, and can thereby update the attenuation factor in real-time. If the mobile user makes a change, it can inform the base station at that time, or during initial access. Result: improved reliability, lower energy consumption, improved traffic safety.
