Claim of US Patent No. 10,194,459

1. A method of relaying a V2X (Vehicle-to-Everything) message in a wireless communication system supporting V2X communication, the method performed by a first UE (User Equipment) and comprising:receiving the V2X message from a second UE;
calculating a resource usage rate of a direct link between a plurality of UEs;
determining a relay scheme of the V2X message by comparing the calculated resource usage rate to a predetermined threshold; and
transmitting the received V2X message to a third UE based on the determined relay scheme,
wherein the threshold is determined based on a type of the V2X message or a type of the second UE,
wherein the threshold is lower when the V2X message is an event-driven message than when the V2X message is a periodic message, and
wherein the threshold is lower when the second UE is a public safety UE than when the second UE is a normal UE.
