Patent ID: 11402513

Abstract:
Wireless communication in 5G or 6G, between vehicles (V2V) and other entities (V2X), offers vast opportunities for collision avoidance and improved traffic flow. Many of these opportunities depend on localizing and identifying particular wireless entities (vehicle, pedestrian, base station, toll booth, security gate, among innumerable others). However, due to vehicle motion, the spatial resolution achievable with satellite signals such as GPS, is generally too poor (several meters) to reliably localize a particular wireless entity, inhibiting many applications. Greatly improved localization may be achieved by arranging for multiple vehicles to acquire the satellite signals at the same time from the same satellites. They then transmit parameters of the satellite signals to a calculating entity (such as one of the vehicles) which then processes the data differentially, determining the relative distances between vehicles. Many errors and uncertainties may thereby cancel. The calculating entity can then broadcast a message indicating the coordinates and wireless addresses of the vehicles. With sub-meter spatial resolution, vehicle localization may be improved, cooperation between vehicles may be enabled, and many collisions may be avoided, saving countless lives, according to some embodiments.
