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.

Abstract: A transmission device in a wireless communication system: determines an encoder having S outputs from among encoders supported by the transmission device, on the basis of the number B of feedback bits, wherein B=S×Q; encodes CSI through the encoder to output S real number values; determines B-bit encoded CSI including Q bits indicating the S real number values, respectively; and transmits the B-bit encoded CSI. The encoders may have different numbers of outputs from each other, and the different numbers of outputs may be predetermined for different feedback bit number ranges.
