MUMBAI, India, Aug. 31 -- Intellectual Property India has published a patent application (202647100236 A) filed by Qualcomm Incorporated on August 19, 2026, for Rate Matching And Signaling In Probability Constellation Shaping In Wi-Fi Systems.
Inventors include Chen, Jialing Li; Baik, Eugene Pctus No; and Tian, Bin.
The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: This disclosure provides methods, components, devices and systems for rate matching and signaling in probability constellation shaping in Wi-Fi systems. Some aspects more specifically relate to a rate matching algorithm and various rules, calculations, procedures, and signaling designs to support rate matching in conjunction with probability constellation shaping. In some examples, a wireless communication device functioning as a transmitter device may implement a rate matching algorithm to determine a pre-forward error correction (FEC) padding boundary, a pre-FEC padding size, a quantity of codewords, and a post-FEC padding size given a presumed payload size after shaping, a codeword size, and an effective code rate. Additionally, or alternatively, a wireless communication device may indicate information associated with an application of a constellation shaping. Such information may indicate a specific constellation shaping combination or whether constellation shaping is set to an ON or OFF sets, or both.
