Abstract: 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.

Abstract: Disclosed are a method for dividing a carrying block of a Low Density Parity Check (LDPC) code and an apparatus therefor. The method for dividing a LDPC code of the present disclosure can obtain a high throughput by using a limited size of shifting network. Moreover, it is possible to prevent degradation in performance due to a minimum size of code block by performing shortening for a large size of code block while minimizing the number of code blocks. Furthermore, in selection of a minimum size of code block, since a minimum size of code block is selected on the basis of shortening for a relatively large size of code block, it is possible to increase the size of the minimum size of code block.
