Quasi-orthogonal spatially-coupled multiple-input, multiple-output

A method of wireless communication performed by a transmitter, comprising:

• generating multiple code blocks based at least in part on a transport block (TB) segmentation procedure;
• mapping the multiple code blocks across N layers of a multiple-input, multiple-output (MIMO) transmission such that each layer of the N layers is assigned a respective portion of the multiple code blocks, the mapping being based at least in part on a quasi-orthogonal spatially-coupled (SC)-MIMO-based mapping scheme that includes a layer-based cyclical shift of the respective portion of the multiple code blocks for one or more layers of the N layers, N being an integer;
• and
• transmitting the MIMO transmission based at least in part on the quasi-orthogonal SC-MIMO-based mapping scheme.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a transmitter, cause the transmitter to:
• generate multiple code blocks based at least in part on a transport block (TB) segmentation procedure;
• map the multiple code blocks across N layers of a multiple-input, multiple-output (MIMO) transmission such that each layer of the N layers is assigned a respective portion of the multiple code blocks, the mapping being based at least in part on a quasi-orthogonal spatially-coupled (SC)-MIMO-based mapping scheme that includes a layer-based cyclical shift of the respective portion of the multiple code blocks for one or more layers of the N layers, N being an integer;
• and
• transmit the MIMO transmission based at least in part on the quasi-orthogonal SC-MIMO-based mapping scheme.
