Abstract

An inter-vehicle communication method and an apparatus for performing the same. The inter-vehicle communication method may include a reception node receiving at least one vehicle-to-vehicle (V2V) message from at least one transmission node and the reception node transmitting a relay V2V message on the basis of the at least one V2V message, wherein the at least one V2V message may include information about adjacent vehicles discovered by the at least one transmission node.

First claim

What is claimed is:

1 . An inter-vehicle communication method comprising:
receiving, by a reception node, at least one vehicle-to-vehicle (V2V) message from at least one transmission node; and transmitting, by the reception node, a relay V2V message on the basis of the at least one V2V message, wherein the at least one V2V message includes information about adjacent vehicles discovered by the at least one transmission node.

2 . The inter-vehicle communication method of claim 1 , wherein,
the at least one V2V message is a V2V message (Type 1) or a V2V message (Type 2), the V2V message (Type 1) includes identification information about all the discovered adjacent vehicles, and the V2V message (Type 2) includes identification information about a vehicle among the discovered adjacent vehicles that changes.

3 . The inter-vehicle communication method of claim 2 , wherein,
the V2V message (Type 1) is transmitted at first intervals, the V2V message (Type 2) is transmitted at second intervals, the first interval is longer than the second interval, and the V2V message (Type 2) is transmitted at least once within the transmission interval of the V2V message (Type 1).

4 . The inter-vehicle communication method of claim 3 , wherein,
a relay V2V message includes a field that is the same as at least one of a plurality of fields included in the at least one V2V message and a relay flag, and the relay flag is a flag for identifying the relay V2V message.

5 . The inter-vehicle communication method of claim 4 , wherein the reception node determines whether to transmit the relay V2V message on the basis of the at least one V2V message and another relay V2V message.

6 . A reception node for inter-vehicle communication, the reception node comprising:
a radio frequency (RF) unit configured to communicate with a transmission node; and a processor operatively connected to the RF unit, wherein, the processor is implemented to receive at least one vehicle-to-vehicle (V2V) message from at least one transmission node and transmit a relay V2V message on the basis of the at least one V2V message, and the at least one V2V message includes information about adjacent vehicles discovered by the at least one transmission node.

7 . The reception node of claim 6 , wherein,
the at least one V2V message is a V2V message (Type 1) or a V2V message (Type 2), the V2V message (Type 1) includes identification information about all the discovered adjacent vehicles, and the V2V message (Type 2) includes identification information about a vehicle among the discovered adjacent vehicles that changes.

8 . The reception node of claim 7 , wherein,
the V2V message (Type 1) is transmitted at first intervals, the V2V message (Type 2) is transmitted at second intervals, the first interval is longer than the second interval, and the V2V message (Type 2) is transmitted at least once within the transmission interval of the V2V message (Type 1).

9 . The reception node of claim 8 , wherein,
a relay V2V message includes a field that is the same as at least one of a plurality of fields included in the at least one V2V message and a relay flag, and the relay flag is a flag for identifying the relay V2V message.

10 . The reception node of claim 9 , wherein the reception node determines whether to transmit the relay V2V message on the basis of the at least one V2V message and another relay V2V message.
