Method for transmitting V2X signal of terminal having limited transmission capability and terminal using the method

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, the method comprising:

• selecting a first resource in a first carrier;
• based on the use of a specific subframe in a second carrier exceeding a transmission capability of the UE considering the first resource, randomly selecting a second resource that includes one or more subframes, excluding the specific subframe, in the second carrier;
• and
• transmitting the V2X signal using the first resource and the second resource,
• wherein the selection of the first resource in the first carrier prior to the selection of the second resource in the second carrier is based on an ordering of the first carrier and the second carrier, and
• wherein the ordering of the first carrier and the second carrier is determined based on a ProSe priority per packet (PPPP) of the V2X signal and a channel busy ratio (CBR).
