V2X communication device and geo-networking transmission method

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.
