Abstract:
A method of multiple input multiple output downlink communications including mapping complex-valued modulation symbols onto one or more transmission layers by mapping complex-valued modulation symbols onto the layers and preceding the complex-valued modulation block of vectors and generating a block of vectors mapped onto at least four antenna ports. A first embodiment employs a maximum of two layers per codeword. A second embodiment employs no more than two codewords.
