Disclosed is a method for receiving a V2X message by a V2X communication device. A method for transmitting a V2X message comprises the steps of: acquiring CBR information indicating a congestion state of a channel; determining a state and substate of a channel for a distributed congestion control (DCC) on the basis of the CBR information; on the basis of the state and substate state, generating transmission period information and transmission structure information for the V2X message; and generating the V2X message on the basis of the transmission period information and the transmission structure information. Here, the transmission period information indicates a transmission period of the V2X message, and the transmission structure information indicates a structure of the V2X message transmitted in the transmission period.
