Abstract:
1. A method of data transmission in a multiple antenna system, the method comprising: generating mapping symbols by mapping modulation symbols for a first codeword and modulation symbols for a second codeword to a plurality of layers; and transmitting the mapping symbols through a plurality of antennas, wherein when a number of the plurality of layers is larger than 4, at least one of the modulation symbols for first codeword and the modulation symbols for the second codeword is mapped to at least 3 layers and, wherein when the number of the plurality of layers is 5, the modulation symbols for the first codeword are mapped to 2 layers and the modulation symbols for the second codeword are mapped to remaining 3 layers, and when the number of the plurality of layers is 6, the modulation symbols for the first codeword are mapped to 3 layers and the modulation symbols for the second codeword are mapped to remaining 3 layers, and when the number of the plurality of layers is 7, the modulation symbols for the first codeword are mapped to 3 layers and the modulation symbols for the second codeword are mapped to remaining 4 layers, and when the number of the plurality of layers is 8, the modulation symbols for the first codeword are mapped to 4 layers and the modulation symbols for the second codeword are mapped to remaining 4 layers.
