Disclosed are a method by which a first device transmits a message in a wireless communication system supporting sidelink, and a device therefor according to various embodiments. The method comprises: a step in which the first device receives a first safety message from a second device; a step of evaluating a collision risk on the basis of the first safety message and generating first event information on the basis of the collision risk evaluation; and a step of transmitting a threat notification message (TNM) including identification information of the second device and the first event information, wherein when the first safety message is a personal safety message (PSM), the threat notification message further includes information on a first risk region determined in response to the first event information.

Method by which first device transmits message in wireless communication system supporting sidelink, and device therefor

Disclosed is a vehicle system including: a first electronic device configured to receive a radio frequency (RF) signal from an external device and process the RF signal to generate data; and a second electronic device configured to receive the data through an Ethernet communication method and perform an operation based on the data, wherein the first electronic device includes: a first signal detector configured to receive a first wake-up signal in a power saving mode state; and a first Ethernet interface configured to attempt an Ethernet connection with the second electronic device when the first signal detector receives the first wakeup signal.
