Abstract: The present application relates to an electronic device and a wireless communication method. The electronic device comprises: a processing circuit, configured to select a modulation codebook from a modulation codebook cluster for use in a multiple-input multiple-output MIMO system on the basis of a channel matrix of the MIMO system, the modulation codebook cluster comprising a plurality of modulation codebooks used by a sending terminal device corresponding to the electronic device for generating modulation signals, wherein the number of data streams transmitted after modulation is greater than the number of orthogonal channels; and a transceiving circuit, configured to send feedback information to the sending terminal device, the feedback information comprising identification information of the selected modulation codebook.
