Method for transmitting data in full duplex system

The present invention in a wireless communication system is a node performing transmit and receive simultaneously using the same resource for the data transmission and reception method. Method in accordance with one embodiment of the present invention, the packet receiving method in the second receiver in the network to support a full-duplex cross each other three or more nodes to the destination based on a transmission request to the first transmitter is sent to the first receiver (request-to-send, RTS) signal comprising: a listening (overhearing); Generating intensity information of the first transmitter and an interference signal between the nodes by using the information for receiving intensity of the listening a RTS signal; The step of looking at the intensity information of the interference signal between the generated node to the second transmitter; May include a; and wherein the packet data when the packet data is received from the second transmitter demodulation and decoding, and transmits a response signal.
