Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

WHAT IS CLAIMED IS:

1. An apparatus for providing vehicle-to-everything (V2X) communications, comprising:

a first communication system configured to access a communication frequency channel during a first time interval; and

a second communication system configured to access the communication frequency channel during a second time interval adjacent to the first time interval;

wherein the first communication system is configured to communicate using cellular based communication, and the second communication system is configured to communicate using an Institute of Electrical and Electronics Engineers (IEEE) 802.11 based communication.

2. The apparatus of claim 1, wherein the first communication system is configured to

communicate cellular communication signals during the first time interval, and the second communication system is configured to communicate IEEE 802.11 based communication signals during the second time interval.

3. The apparatus of claim 1, wherein the first communication system is configured to

communicate during a first set of time intervals and the second communication system is configured to communicate during a second set of time intervals, wherein the first set of time intervals alternates with the second set of time intervals such that each time interval from the first set of time intervals is adjacent to a time interval from the second set of time intervals, and wherein the first time interval is included in the first set of time intervals, and the second time interval is included in the second set of time intervals.

4. The apparatus of claim 1, wherein the first communication system is an LTE C-V2X

communication system, and the second communication system is an IEEE 802.11 based DSRC or ITS-G5 communication system.

5. The apparatus of claim 1, wherein the first time interval is a predetermined, fixed time slot dedicated to the first communication system, and the second time interval is a predetermined, fixed time slot dedicated to the second communication system.

6. The apparatus of claim 1, wherein the first time interval and the second time interval are predetermined based at least in part on a level of usage of cellular communications and IEEE 802.11 based communications in a geographic area proximate to the apparatus.

7. The apparatus of claim 6, wherein the level of usage of cellular communications and IEEE 802.11 based communications is determined based at least in part on a plurality of resource requests from a plurality of users in the geographic area proximate to the apparatus.

8. The apparatus of claim 6, wherein the level of usage of cellular communications and IEEE 802.11 based communications is determined based at least in part on historical communication usage of the geographic area proximate the apparatus.

9. The apparatus of claim 1, further configured to receive a reservation request message and to identify a start of the first time interval based at least in part on the reservation request message.

10. The apparatus of claim 1, wherein the first communication system is configured to:

sense that the communication frequency channel is vacant; and

access the communication frequency channel in response to sensing that the communication frequency channel is vacant;

wherein the first time interval begins when the first communication system senses that the communication frequency channel is vacant.

11. The apparatus of claim 1, wherein the first time interval and the second time interval are separated by a pause period.

12. The apparatus of claim 11, wherein the pause period is reduced for ultra-high priority communications.

13. A method of providing vehicle-to-everything (V2X) communications, the method

comprising:

accessing, by a first communication system, a communication frequency channel during a first time interval using cellular communication; and

accessing, by a second communication system, the communication frequency channel during a second time interval using an Institute of Electrical and Electronics Engineers (IEEE) 802.11 based communication;

wherein the first time interval is adjacent to the second time interval.

14. The method of claim 13, wherein the first communication system is configured to

communicate cellular communication signals during the first time interval, and the second communication system is configured to communicate IEEE 802.11 based communication signals during the second timer interval.

15. The method of claim 13, wherein the first communication system is configured to

communicate during a first set of time intervals and the second communication system is configured to communicate during a second set of time intervals, wherein the first set of time intervals alternate with the second set of time intervals, wherein the first set of time intervals alternates with the second set of time intervals such that each time interval from the first set of time intervals is adjacent to a time interval from the second set of time intervals, and wherein the first time interval is included in the first set of time intervals, and the second time interval is included in the second set of time intervals.

16. The method of claim 13, wherein the first communication system is an LTE C-V2X

communication system, and the second communication system is an IEEE 802.11 based DSRC or ITS-G5 communication system.

17. One or more Computer-readable media (CRM) comprising instructions, upon execution of the instructions by one or more processors, cause the one or more processors to:

access, by a first communication system, a communication frequency channel during a first time interval using cellular vehicle-to-everything (V2X) communication; and

access, by a second communication system, the communication frequency channel during a second time interval using an Institute of Electrical and Electronics Engineers (IEEE) 802.11 based V2X communication;

wherein the first time interval is adjacent to the second time interval.

18. The one or more CRM of claim 17, wherein the first time interval is a predetermined, fixed time slot dedicated to the first communication system, and the second time interval is a predetermined, fixed time slot dedicated to the second communication system.

19. The one or more CRM of claim 17, wherein the first time interval and the second time interval are predetermined based at least in part on a level of usage of cellular

communications and IEEE 802.11 based communications in a geographic area proximate the first and second communication systems.

20. The one or more CRM of claim 17, wherein the instructions further cause the one or more processors to:

sense that the communication frequency channel is vacant; and

access, by the first communication system, the communication frequency channel in response to sensing that the communication frequency channel is vacant;

wherein the first time interval begins when the first communication system senses that the communication frequency channel is vacant.
