Abstract
Methods, systems, and devices for wireless communications are described. The described techniques generally provide for spatially coupled multiple-in multiple-out (MIMO) signaling for a single codeword across multiple layers. A transmitting device may transmit, via multiple time-frequency resources using multiple spatial layers, a set of code blocks associated with a codeword. At a first time-frequency resource, each code block of a first subset of the set of code blocks may be mapped to a respective transmission layer, and at a second time-frequency resource, each code block of a second subset of the set of code blocks may be mapped to a respective transmission layer, where the second set of code blocks is staggered from the first set of code blocks. By staggering code blocks across multiple time-frequency resources, a receiving wireless device may cancel out interference of one or more previously decoded code blocks.
