Data transmission method for wireless local area networks
A recently granted patent (Publication Number: US12003457B2) discloses a data transmission method for wireless local area networks, focusing on enhancing efficiency and reducing interference. The method involves an access point (AP) generating a scheduling frame with specific trigger frames for different stations (STAs), scheduling them for uplink data transmission on non-overlapping frequency channels. The patent emphasizes the use of a protocol beyond the 802.11ax standard, ensuring compatibility with evolving technologies. Additionally, the method includes features like bandwidth indication information and support for full-duplex transmission, enhancing the overall network performance.
Furthermore, the patent extends to an apparatus for implementing the data transmission method in wireless local area networks. This apparatus includes processors and memories to execute operations like generating scheduling frames, handling hybrid uplink data, and sending multi-user block acknowledgments. The apparatus ensures efficient data transmission by incorporating advanced features like indication information for preventing misreading and detailed user information fields for STAs. With a focus on improving network capacity and reducing interference, this patent showcases advancements in wireless communication technologies, catering to the evolving needs of modern wireless networks.
