Abstract

The subject matter described herein is directed towards a technology that increases the reliability of transmitting information, and extends the coverage of a vehicle-to-everything (V2X) network by propagating received information in a multiple-stage chain communication in a wireless communication system. A transmitting device transmits a communication message with repetition data indicating number of times the communication message is to be retransmitted in the wireless communication system. A receiving device determines from the repetition data that the communication message is intended to be retransmitted, modifies (e.g., decrements) the repetition data, and retransmits the communication message in association with the modified repetition data.

Claims (34)

1. A method, comprising:

determining, by a transmitting device of a wireless communication system and comprising a processor, repetition data comprising a retransmission limiting value representing a number of times a communication message is to be retransmitted in the wireless communication system, wherein the transmitting device comprises a local manager; and

transmitting, by the transmitting device, the communication message in association with the repetition data, wherein the transmitting comprises broadcasting the communication message.

2. The method of claim 1 , wherein the transmitting of the communication message further comprises transmitting the communication message in further association with resource information comprising resources to be used in a retransmission of the communication message.

3. The method of claim 1 , wherein the transmitting of the communication message further comprises transmitting the communication message in further association with timing information and frequency information to be used in a retransmission of the communication message.

4. The method of claim 1 , further comprising, selecting, by the transmitting device, an antenna panel for the transmitting of the communication message.

5. The method of claim 4 , wherein the selecting of the antenna panel for transmitting the communication message comprises choosing the antenna panel based on a previously established connection.

6. The method of claim 4 , wherein the selecting of the antenna panel for transmitting the communication message comprises choosing the antenna panel based on vehicle-to-everything network size and type information.

7. The method of claim 4 , wherein the selecting of the antenna panel for the transmitting of the communication message comprises choosing the antenna panel randomly or pseudo-randomly when there is a known number of panels in a vehicular network.

8. A receiver device of a wireless communication system, the receiver device comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising

receiving a communication message, the communication message associated with received repetition data indicating that the communication message is intended to be retransmitted;

determining, from the received repetition data, that the communication message is intended to be retransmitted at least one more time;

modifying the received repetition data into modified repetition data that indicates that the communication message is intended for retransmission one fewer time than was indicated in the received repetition data;

selecting an antenna panel for the retransmission of the communication message; and

retransmitting the communication message in association with the modified repetition data.

9. The receiver device of claim 8 , wherein the modifying of the repetition data into the modified repetition data indicates that the communication message is no longer intended for further retransmission before retransmitting the communication message in association with the modified repetition data.

10. The receiver device of claim 8 , wherein the retransmitting of the communication message comprises broadcasting the communication message.

11. The receiver device of claim 8 , wherein the operations further comprise receiving resource data associated with the communication message, the resource data specifying resources to be used by the receiver device in the retransmission of the communication message, and wherein the retransmitting of the communication message in association with the modified repetition data comprises using the resource data.

12. The receiver device of claim 8 , wherein the selecting of the antenna panel for the retransmitting of the communication message comprises choosing the antenna panel based on a previously established connection.

13. The receiver device of claim 8 , wherein the selecting of the antenna panel for the retransmitting of the communication message comprises choosing the antenna panel based on vehicle-to-everything network size and type information.

14. The receiver device of claim 8 , wherein the selecting of the antenna panel for the retransmitting of the communication message comprises choosing the antenna panel randomly or pseudo-randomly when there is a known number of beams in a vehicular network.

15. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of a receiver device of a wireless communication system, facilitate performance of operations, the operations comprising:

receiving a broadcast communication message, the broadcast communication message associated with received repetition data;

determining, based on the received repetition data, whether the broadcast communication message is intended to be rebroadcast; and

in response to the determining indicating that the broadcast communication message is intended for a rebroadcast:

selecting an antenna panel for the rebroadcast of the broadcast communication message, and

rebroadcasting the broadcast communication message resulting in a rebroadcast communication message.

16. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise modifying the received repetition data into modified repetition data that indicates that the broadcast communication message is intended for the rebroadcasting one fewer time than was indicated in the received repetition data.

17. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise receiving resource data associated with the broadcast communication message, the resource data specifying resources to be used by the receiver device in the rebroadcasting of the broadcast communication message, and wherein the rebroadcasting of the broadcast communication message comprises using the resource data.

18. The non-transitory machine-readable medium of claim 15 , wherein the selecting of the antenna panel for the rebroadcast of the broadcast communication message comprises choosing the antenna panel based on a previously established connection.

19. The non-transitory machine-readable medium of claim 15 , wherein the selecting of the antenna panel for the rebroadcast of the broadcast communication message comprises choosing the antenna panel based on vehicle-to-everything network size and type information.

20. The non-transitory machine-readable medium of claim 15 , wherein the selecting of the antenna panel for the rebroadcast of the broadcast communication message comprises choosing the antenna panel randomly or pseudo-randomly when there is a known number of beams in a vehicular network.
