Disclosed in various embodiments are a method by which a first device transmits a collective perception message (CPM) in a wireless communication system, and a device therefor. Disclosed are a method by which a first device transmits a collective perception message (CPM) in a wireless communication system, and a device therefor, the method comprising the steps of: receiving a first message from a second device; acquiring sensing information about adjacent objects; and transmitting the CPM on the basis of the sensing information, wherein the first device determines whether object information that overlaps with first object information acquired from the first message is included in the sensing information, and determines whether to include the overlapping object information in the CPM on the basis of the distance to the second device.
