V2X communication device and geo-networking transmission method

1. A GeoNetworking transmission method of a V2X communication device, the method comprising:

receiving a beacon packet or a single hop broadcast (SHB) packet;

configuring location information, the location information including information about at least one neighboring V2X communication device executing a GeoNetworking protocol;

determining a forwarder from neighboring V2X communication devices included in a location table and setting an address of the determined forwarder to a link layer address; and

transmitting a GeoNetworking packet to a first service channel (SCH) based on the link layer address,

wherein a header of the beacon packet or the SHB packet includes SCH information for a multi-channel operation (MCO),

wherein the SCH information indicates at least one of a current SCH ID or a next SCH ID that is accessed by a neighboring V2X communication device transmitting the beacon packet or the SHB packet, and

wherein based on the beacon packet or the SHB packet including the SCH information being received on a specific SCH, the SCH information indicates an ID of another SCH other than the specific SCH.

2. The method of claim 1 , wherein the location information includes at least one of GeoNetworking address information, link layer address information, type information, position vector information, or the SCH information about at least one neighboring V2X communication device receiving the GeoNetworking packet.

3. The method of claim 1 , wherein the determining of the forwarder further comprises determining, as the forwarder, one of one or more V2X communication devices using the first SCH among the neighboring V2X communication devices.

4. The method of claim 1 , wherein the beacon packet or the SHB packet including the SCH information is received on a control channel (CCH) or a SCH.

5. A V2X communication device comprising:

a memory configured to store data;

a communication unit including a transceiver configured to transmit and receive a radio signal including a GeoNetworking packet; and

a processor configured to control the memory and the communication unit,

wherein the processor is configured to:

receive a beacon packet or a single hop broadcast (SHB) packet;

configure location information, the location information including information about at least one neighboring V2X communication device executing a GeoNetworking protocol;

determine a forwarder from neighboring V2X communication devices included in a location table and set an address of the determined forwarder to a link layer address; and

transmit the GeoNetworking packet to a first service channel (SCH) based on the link layer address,

wherein a header of the beacon packet or the SHB packet includes SCH information for a multi-channel operation (MCO),

wherein the SCH information indicates at least one of a current SCH ID or a next SCH ID that is accessed by a neighboring V2X communication device transmitting the beacon packet or the SHB packet, and

wherein based on the beacon packet or the SHB packet including the SCH information being received on a specific SCH, the SCH information indicates an ID of another SCH other than the specific SCH.

6. The V2X communication device of claim 5 , wherein the location information includes at least one of GeoNetworking address information, link layer address information, type information, position vector information, or the SCH information about at least one neighboring V2X communication device receiving the GeoNetworking packet.

7. The V2X communication device of claim 5 , wherein the determining of the forwarder is performed by determining, as the forwarder, one of one or more V2X communication devices using the first SCH among the neighboring V2X communication devices.

8. The V2X communication device of claim 5 , wherein the beacon packet or the SHB packet including the SCH information is received on a control channel (CCH) or a SCH.
