Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may map two or more code blocks across N layers of a multiple-input, multiple-output (MIMO) transmission by separating each code block into N code block partitions and assigning each layer a respective code block partition, N being an integer greater than two. The mapping of the code blocks may be based at least in part on a spatially-coupled MIMO-based mapping scheme. The transmitter may map two or more interference-mitigating code blocks across the N layers by separating each interference-mitigating code block into N interference-mitigating code block partitions and assigning each layer a respective interference-mitigating code block partition. Mapping the interference-mitigating code blocks may be complementary to the mapping of the code blocks. The transmitter may transmit the MIMO transmission based at least in part on the mapping. Numerous other aspects are described.
