Abstract: Provided are a method for transmitting a vehicle-to-everything (V2X) signal performed by a user equipment (UE) having a limited transmission capability in a multi-carrier system and a UE using the method. The method includes selecting a first resource in a first carrier, if using a specific subframe in a second carrier exceeds a transmission capability of the UE considering the first resource, selecting a second resource randomly among the remaining subframes except the specific subframe in the second carrier and transmitting the V2X signal using the first resource and the second resource.

Abstract: Disclosed is a method for transmitting and receiving an alarm in V2X communication so as to prevent waste of power and radio resources. The method for transmitting and receiving an alarm according to the present invention involves transmitting an alarm message containing the rating information of an actual event, prior to transmitting a message containing information of the event. On the basis of the rating, a receiving end can decide whether or not to receive a subsequent message, thereby saving power.
