Abstract: The present disclosure relates to a machine learning-based vector quantization method and device for limited feedback in a wireless communication system. The method for providing feedback on a selection vector by a reception terminal in a wireless communication system according to one embodiment of the present disclosure comprises the steps of: obtaining a feature matrix on the basis of a reception signal from a transmission terminal; obtaining a selection vector with respect to one or more codeword candidates included in a predetermined codebook, on the basis of the feature matrix; and sending feedback on the selection vector to the transmission terminal, wherein the selection vector comprises the same number of elements as the number of the one or more codeword candidates and may comprise one or more elements which are not 0.
