Abstract: 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). Then, the interface circuit may receive a modified response frame associated with the second electronic device, where the modified response frame is different from a response frame associated with the trigger frame specified by the IEEE 802.11 standard. When the second electronic device indicates support for the modified response frame during association with the electronic device, the interface circuit may define parameters associated with the modified response frame in an association response.

Abstract: 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 management frame addressed to a second electronic device. Then, the interface circuit may provide a trigger frame addressed to the second electronic device, where the trigger frame includes a trigger-frame variant that is compatible with an IEEE 802.11 standard. Next, the interface circuit may receive a modified response frame associated with the second electronic device, where the modified response frame is different from a response frame associated with the trigger frame specified by the IEEE 802.11 standard, and modifications to the modified response frame are specified in the management frame.

Abstract: An auto-adjusting device for adjusting a drive voltage of a light receiver includes an amplifier, an analog-to-digital converter, a determination control circuit and a boost circuit. The amplifier is configured to amplify an analog signal generated by the light receiver. The analog-to-digital converter is configured to convert the amplified analog signal to a digital signal. The determination control circuit is configured to process and determine the digital signal, and output a control signal when the processed digital signal satisfies a predetermined condition. The boost circuit is configured to receive the control signal and adjust the drive voltage of the light receiver.
