Patent Application: Spatially Coupled MIMO Signaling Techniques
Summary
The USPTO has published a new patent application (US20260088947A1) detailing techniques for spatially coupled multiple-input multiple-output (MIMO) signaling in wireless communications. The application describes methods for transmitting code blocks across multiple layers and time-frequency resources to reduce interference.
What changed
This document is a publication of a patent application (US20260088947A1) filed by inventors Jing JIANG, Wei YANG, Gabi SARKIS, and Thomas Joseph RICHARDSON with the USPTO on October 22, 2025. The application outlines novel methods, systems, and devices for wireless communications, specifically focusing on spatially coupled multiple-input multiple-output (MIMO) signaling techniques. The core innovation involves transmitting a single codeword across multiple layers and time-frequency resources in a staggered manner, enabling a receiving device to cancel interference from previously decoded code blocks.
As this is a patent application, it does not impose immediate regulatory obligations or compliance deadlines on entities. However, companies operating in the wireless communication and technology sectors, particularly those involved in developing or manufacturing telecommunications equipment, should be aware of this potential intellectual property. Companies may wish to review the application to assess its relevance to their existing or future product development and to understand potential licensing or patent infringement considerations.

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.
