  • Publication number: 20240289292
    Abstract: Embodiments relate to an integrated circuit of an electronic device that coordinates activities with another integrated circuit of the electronic device. The integrated circuit includes an interface circuit and a processor circuit. The interface circuit communicates over a multi-drop bus connected to multiple electronic components. The processor circuit receives an authorization request from the integrated circuit via the interface circuit and the multi-drop bus. The received authorization request relates to authorization to perform an activity on the other integrated circuit. In response to receiving the authorization request, the processor circuit determines whether the other integrated circuit is authorized to execute the activity.

  • Publication number: 20240098655
    Abstract: Techniques described herein are directed toward smart external interference detection and avoidance. An example method includes determining a first received signal strength indicator (RSSI) value of a received first signal across a radio band, wherein the first RSSI value is based at least in part on a second signal transmitted by an interfering device. The first received RSSI value is compared with a threshold value. A first gain adjustment value is determined for a receiver chain of the first computing device and a second gain adjustment value of a transmitter chain based at least in part on the comparison. A first gain of a first amplifier of the receiver chain is adjusted based at least in part on the first gain adjustment value. A second gain of a second amplifier of the transmitter chain is adjusted based at least in part on the second gain adjustment value.

  • Patent number: 11812438
    Abstract: An electronic device that selectively provides a trigger frame is described. During operation, the electronic device may receive a frame from a recipient electronic device, where the frame includes information that specifies a maximum uplink multi-user transmit duration of the recipient electronic device. Moreover, the electronic device may selectively provide the trigger frame to the recipient electronic device that specifies an uplink OFDMA frame or an uplink MIMO frame associated with the recipient electronic device. The trigger frame may be selectively provided when a transmit time corresponding to the uplink OFDMA frame or the uplink MIMO frame is less than or equal to the maximum uplink multi-user transmit duration.

  • Publication number: 20230089303
    Abstract: A transmitter of an electronic device may include one or more intermediate frequency stage circuitries. Processing circuitry may select one or more intermediate frequency stage circuitries of the transmitter that output one or more intermediate frequency signals that cause interference with a signal received by a receiver of the electronic device. The processing circuitry may adjust settings of the one or more intermediate frequency stage circuitries to reduce interference with the signal received by the receiver and store the settings. Subsequently, the processing circuitry may receive an indication of an operational mode of the receiver and apply the settings to the one or more intermediate frequency stage circuitries based on the indication.

  • Patent number: 11147046
    Abstract: An interface circuit in an electronic device (such as an access point) may request a channel status in order to specify a subset of one or more frequency sub-bands. During operation, the interface circuit may provide at least a frame to the recipient electronic device, where the frame requests the channel status for the one or more frequency sub-bands. Then, the electronic device may receive one or more measurement results from the recipient electronic device that specify the subset of the one or more frequency sub-bands (such as one or more RUs) that are not to be used when communicating with the recipient electronic device.
