Abstract:
This invention is a method and an apparatus to up link transmission of data from a user equipment to a base station for single user multiple input, multiple output. This invention includes receiving at least one codeword, permuting the received codewords, precoding the permuted codewords and transmitting the predecoded codewords on plural antennas. The codewords may be permuted by layer permutation or by codeword permutation.
