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. Using the electronic device and the wireless communication method of the present application can increase the number of data streams that can be transmitted independently in a MIMO system, thus improving transmission efficiency.
