Abstract

Communication between autonomous vehicles, in 5G or 6G, is necessary for cooperative hazard avoidance and to coordinate the flow of traffic. However, before cooperative action, each vehicle must determine the wireless address of other vehicles in proximity, so that they can communicate directly with each other. Methods and systems disclosed herein include a computer-readable wireless “connectivity matrix”, an array of black and white squares showing a connectivity code. The connectivity code may be the vehicle's wireless address, an index code, or other information about the vehicle. The connectivity code may be an index in a tabulation of information that provides the wireless address, among other data. Other vehicles, or their cameras, may read the connectivity matrix, determine the code therein, and find the vehicle's wireless address. After determining the wireless address of the other vehicles, the vehicles can then communicate and cooperate to avoid accidents and facilitate the flow of traffic.

First claim

The invention claimed is:

1. A wireless entity comprising:
a) a matrix comprising a plurality of square or rectangular fields, the matrix displayed visually in or on the wireless entity, the fields arranged in a rectangular array, each field colored either black or white according to a binary code, the binary code comprising data related to a wireless address of the wireless entity;
b) wherein the binary code indicates an index of a particular entry of a tabulation, the tabulation comprising a plurality of entries, each entry related to a wireless vehicle or a wireless fixed asset, respectively, and each entry indicating the wireless address of the related wireless vehicle or wireless fixed asset.

2. The wireless entity of claim 1 , wherein the wireless entity is configured to communicate according to 5G or 6G technology.

3. The wireless entity of claim 1 , the matrix further comprising a border comprising further fields arranged peripherally around the matrix and colored black or white according to a predetermined pattern.

4. The wireless entity of claim 1 , wherein the binary code further indicates the wireless address of the wireless entity.

5. The wireless entity of claim 1 , wherein the wireless entity comprises a first vehicle, and the matrix is further configured to indicate, to a second vehicle, the wireless address of the first vehicle.

6. The wireless entity of claim 5 , wherein the matrix is configured to be readable by a camera on the second vehicle from a predetermined distance, the predetermined distance in the range of 20 to 100 meters.

7. The wireless entity of claim 1 , wherein each field has a predetermined size in the range of 5 to 20 millimeters.

8. The wireless entity of claim 1 , wherein the wireless entity is a base station of a wireless network, and the code comprises a frequency of a broadcast channel of the base station.

9. The wireless entity of claim 1 , wherein the entity is a fixed asset comprising a traffic signal or a highway sign or a roadside building and the code further indicates a wireless address of a receiver associated with the wireless entity.

10. The wireless entity of claim 1 , wherein:
a) each field comprises an illuminator, respectively;
b) each illuminator is powered individually; and
c) the code is determined by which of the illuminators are powered and which of the illuminators are unpowered.

11. The wireless entity of claim 1 , wherein:
a) each field comprises a filter, respectively, each filter having an individually controllable opacity; and
b) the code is determined by which of the filters are controlled to have a high opacity and which filters are controlled to have a low opacity.

12. The wireless entity of claim 1 , wherein the matrix further comprises 48 fields colored black or white according to a MAC (medium access code) address, surrounded by a border comprising 32 fields colored black or white according to a predetermined pattern.

13. Non-transitory computer-readable media in a first vehicle, the media including instructions that when executed by a computing environment cause a method to be performed, the method comprising:
a) detecting, in or on a second vehicle, a connectivity matrix comprising a plurality of fields colored black or white according to a code; and
b) determining, from the code, a wireless address of the second vehicle;
c) wherein the determining of the wireless address comprises:
d) retrieving, from a tabulation of entries, a particular entry according to the code; and
e) determining, from the particular entry, the wireless address of the second vehicle.

14. The media of claim 13 , the method further comprising transmitting, according to the wireless address, a message to the second vehicle.

15. The media of claim 13 , wherein the code is configured to indicate whether the second vehicle is autonomous or semi-autonomous or human-driven.

16. A base station of a wireless network, the base station comprising:
a) a visibly displayed connectivity matrix comprising a plurality of fields arranged in a rectangular array, each field colored black or white according to a code, the code configured to indicate a particular entry, in a tabulation of entries, according to the code, the particular entry comprising a particular frequency; and
b) a transmitter configured to transmit system information messages on the particular frequency.

17. The base station of claim 16 , wherein the system information messages indicate how user devices can become registered with the base station.

18. The base station of claim 16 , further comprising a receiver configured to receive messages on a second frequency, different from the particular frequency, the second frequency indicated in the system information messages.
