Abstract:
1. A method for transmitting information over M layers, where M is a positive integer value representing a number of spatial layers, and M≧2, the method comprising: receiving at least two codewords to transmit, wherein the at least two codewords each comprises a plurality of symbols, each symbol composed of two or more code bits; grouping the plurality of symbols in the at least two codewords into M groups using an interleaver comprising M same-level sub-interleavers with one sub-interleaver per group; mapping the M groups to the M layers, wherein the plurality of symbols in each codeword are mapped to non-corresponding symbol positions across the M layers; and transmitting the M layers on an uplink from a user equipment to a base station using single carrier frequency division multiple access (SC-FDMA).
