Method for transmitting data file in wireless communication system and device therefor

A user equipment (UE) comprising:

• a radio frequency (RF) transceiver;
• and
• a processor connected to the RF transceiver,
• wherein the processor controls the RF transceiver to receive configuration information including information about a size and a transmission period of a periodically transmitted vehicle to everything (V2X) message, determine a UE state based on state information obtained for the UE, transmit the V2X message based on the configuration information, and segment and transmit a data file into a first segmentation size or a second segmentation size based on the UE state and the configuration information.

A method by a network comprising:

• transmitting configuration information including information about a size and a transmission period of a periodically transmitted vehicle to everything (V2X) message;
• receiving the V2X message based on the configuration information;
• and
• receiving a data file segmented and transmitted into a first segmentation size or a second segmentation size based on state information for a user equipment (UE) and the configuration information.
