Abstract: Method, apparatus and systems are disclosed that may be implemented. One method implemented by a transceiver, is directed to transmission via a plurality of beams. The method includes obtaining an input bit stream and bit mapping bits of the input bit stream into at least a first stream and a second stream. The method further includes, generating one or more complex symbols using the first stream, selecting a Space-Time (ST) spreading matrix from a plurality of ST spreading matrices and spreading the generated one or more complex symbols over the selected ST spreading matrix to generate one or more dispersed ST codewords. In this method the transceiver maps the one or more dispersed ST codewords to a plurality of beams and transmits the mapped one or more dispersed ST codewords over the plurality of beams.
