Abstract
The present invention discloses a method for mapping a codeword to a layer in a multi-input multi-output system, the method includes: grouping current layers in a multi-input multi-output system according to the number of current codewords, and mapping each codeword to the layer of a group to which the codeword corresponds. The present invention further discloses a device for mapping a codeword to a layer in a multi-input multi-output system, the device includes: a layer grouping unit and a mapping unit, wherein the layer grouping unit is used for grouping current layers in a multi-input multi-output system according to the number of current codewords; and the mapping unit is used for mapping each codeword to the layer of a group to which the codeword corresponds. The present invention is easy to be implemented, and the mapping manner for mapping a codeword to a layer is more reasonable.
