First Claim
Patent Images
1. A method for performing, by a first road side unit (RSU), V2X communication in a wireless communication system, the method comprising:
- receiving event occurrence information and a hop level, from a second RSU,wherein the hop level is generated by the second RSU based on a type of the event occurrence information received from a first user equipment (UE);
decreasing of the received hop level by one;
when the decreased hop level is zero;
broadcasting the event occurrence information to a second UE in a coverage of the first RSU, andwherein the event occurrence information and the decreased hop level are not transmitted to a third RSU located in a neighbor of the first RSU; and
when the decreased hop level is larger than zero;
broadcasting the event occurrence information to the second UE in the coverage of the first RSU, andtransmitting the event occurrence information and the decreased hop level to the third RSU,wherein the first UE and the second UE are included in vehicles, andwherein the second RSU and the third RSU are connected with the first RSU.

Abstract
Provided are a method by which a device performs V2X communication in a wireless communication system, and a device for supporting the same. The device receives event termination information from a terminal and can transmit the event termination information to a neighboring device. The terminal is provided in a vehicle for V2X communication, and the event termination information can be information indicating that an event occurring in the terminal has been terminated.

5. A first road side unit (RSU) performing V2X communication in a wireless communication system, the first RSU comprising:
-
a memory;
a transceiver; and
a processor operatively coupled to the memory and the transceiver, wherein the processor is configured to;control the transceiver to receive event occurrence information and a hop level, from a second RSU, wherein the hop level is generated by the second RSU based on a type of the event occurrence information received from a first user equipment (UE); decrease of the received hop level by one; when the decreased hop level is zero; control the transceiver to broadcast the event occurrence information to a second UE in a coverage of the first RSU, and wherein the event occurrence information and the decreased hop level are not transmitted to a third RSU located in a neighbor of the first RSU; and when the decreased hop level is larger than zero; control the transceiver to broadcast the event occurrence information to a second UE in a coverage of the first RSU, and control the transceiver to transmit the event occurrence information and the decreased hop level to the third RSU, wherein the first UE and the second UE are included in vehicles, and wherein the second RSU and the third RSU are connected with the first RSU. - View Dependent Claims (6)
