Determining Relative Locations by Differential Analysis in 5G and 6G

A method for a first wireless device to communicate with a second wireless user device and a third wireless device, the method comprising:

• a) broadcasting a message offering to determine precision locations of any responding wireless user devices, and specifying a particular time;
• b) receiving, from the second wireless device, a data message indicating data acquired, at the particular time, by the second wireless device from navigation satellite signals;
• c) receiving, from the third wireless device, a further data message indicating further data acquired, at the particular time, by the third wireless device from the navigation satellite signals;
• and
• d) determining, by differential analysis of the data and the further data, a relative location of the second wireless device relative to the third wireless device, or vice-versa.

A method for a first vehicle to determine a location of a second vehicle, the method comprising:

• a) synchronizing a clock of the first vehicle with a clock of the second vehicle;
• b) simultaneously, at a predetermined time, acquiring a first set of navigation satellite signals and determining a first value of a parameter of the signals;
• c) receiving, from the second vehicle, a data message indicating a second value of the parameter, the second value determined according to a second set of navigation satellite signals acquired by the second vehicle at the predetermined time;
• and
• d) determining, according to the first value and the second value, a location of the second vehicle relative to the first vehicle.
