Abstract: Proposed are a method for carrying out wireless communication by a first device, and a device supporting the same. For example, on the basis of an interworking relationship between the first device and a second device not being established, the first device may transmit a first message, and reception of at least one of a second message or a third message may be omitted. For example, the first device may establish the interworking relationship between the first device and the second device. For example, on the basis of the interworking relationship being established, the first device may receive at least any of the second message or the third message.
