Application: Methods, devices and systems for improving transmission protection rates for radio circuits that coexist with wlan circuits (Patent ID: US20240107515A1)
The patent filed by Infineon Technologies AG describes a method, devices, and systems for managing coexisting wireless communications in a device. The method involves determining an estimated duration for future communications of a coexisting wireless circuit and transmitting clear-to-send-to-self frames based on this estimation. If the actual duration of the coex communications exceeds the estimated duration, a second frame with an extended duration is transmitted. The patent also covers devices with WLAN circuits and controller sections for managing coex communications, as well as systems where WLAN and coex communication circuits operate on the same medium but follow different protocols like Bluetooth, Zigbee, or Thread.
The claims in the patent detail the specific steps involved in the method, such as determining estimated durations, transmitting CTS-to-self frames, and managing WLAN activities based on coex communication timings. The devices described include WLAN circuits, MAC circuits, and PHY circuits for handling different types of frames and communications. The systems outlined involve WLAN circuits and coex communication circuits communicating on the same medium but following different protocols, with the ability to determine communication timings and durations based on data exchange between the circuits. Overall, the patent focuses on efficiently managing coexisting wireless communications to optimize performance and avoid interference between different wireless protocols.
