Publication number: 20240080660Abstract: An electronic device (such as an access point) that receives a modified response frame is described. During operation, an interface circuit in the electronic device may provide a trigger frame addressed to a second electronic device, where the trigger frame includes a trigger-frame variant that is compatible with an IEEE 802.11 standard (such as IEEE 802.11ax or a subsequent IEEE 802.11 standard).

Publication number: 20210242964Abstract: The present invention relates to HARQ, particularly for IEEE 802.11, i.e. Wi-Fi. The invention proposes a transmitting device for supporting such HARQ, in which the order of scrambling and encoding is changed compared to the conventional transmitter.
