Abstract:
1. A method of data transmission in a multiple antenna system, the method comprising: determining, by a processor, the number of layers; generating, by the processor, mapping symbols by mapping modulation symbols for a first codeword and modulation symbols for a second codeword to each layer; and transmitting, by the processor, the mapping symbols, wherein at least one of the first codeword and the second codeword is mapped to at least 3 layers and the number of layers is larger than 3, wherein when the number of layers is an odd number larger than 4, a number of mapped layers for the second codeword is larger than a number of mapped layers for the first codeword by one, and when the number of layers is an even number larger than 4, a number of mapped layers for the second codeword is identical to a number of mapped layers for the first codeword.
