Abstract: In a wireless communication system, a transmission device may transmit semantic data. The transmission device may: transmit a first semantic message including the semantic data to a reception device; receive a first semantic feedback for the first semantic message from the reception device; and on the basis that a result included in the semantic feedback does not agree with the result intended by the transmission device through the first semantic message, transmit a second semantic message including first redundancy data related to the semantic data to the reception device.
