Abstract:
1. A method of data transmission in a multiple antenna system, the method comprising: generating, by a processor, mapping symbols by mapping modulation symbols for a first codeword and modulation symbols for a second codeword to a plurality of layers; and transmitting, by the processor, the mapping symbols, wherein when a number of the plurality of layers is an odd number larger than 4, a number of mapped layers for the modulation symbols for the second codeword is larger than a number of mapped layers for the modulation symbols for the first codeword by one, and wherein when the number of the plurality of layers is an even number larger than 4, a number of mapped layers for the modulation symbols for the second codeword is identical to a number of mapped layers for the modulation symbols for the first codeword, and wherein when the number of the plurality of layers is 5, 6, 7, or 8, the modulation symbols for the first codeword and the modulation symbols for the second codeword are mapped to layers based on the table below: wherein, in the above table, d
