    Abstract: An interface circuit in an electronic device (such as an access point) may utilize a configurable wake-up-frame format. During operation, the interface circuit may receive a wake-up-radio (WUR)-setup request associated with a recipient electronic device, where the WUR-setup request specifies a proposed configurable wake-up-frame format. In response, the electronic device may determine the configurable wake-up-frame format to be used based at least in part on the proposed configurable wake-up-frame format. Then, the interface circuit may provide a WUR-setup response intended for the recipient electronic device, where the WUR-setup response specifies the configurable wake-up-frame format selected for use. Note that the configurable wake-up-frame format may specify a payload length in a wake-up frame and/or one or more operations of at least one of the recipient electronic device or the electronic device after the wake-up frame is transmitted by the electronic device.

    IPC: H04W52/02

    Abstract: An interface circuit in an electronic device (such as an access point) may provide a wake-up beacon to a recipient electronic device. During operation, the interface circuit may provide a wake-up beacon associated with a predefined sub-channel in one or more channels in a band of frequencies, where the wake-up beacon is for a wake-up radio in the recipient electronic device. Moreover, the wake-up beacon may be provided within an associated time interval, such as a keep-alive interval of the electronic device. In some embodiments, the wake-up beacon includes a field with channel information that specifies one or more second channels used by a main radio in the recipient electronic device. Alternatively or additionally, the wake-up beacon may include a field with service information that specifies one or more types of services and/or a field with information specifying a transmit power of the interface circuit.

    Abstract: A method for controlling transmission power in accordance with a total transmission power limit in a multi-radio wireless communication device including a master radio and a slave radio is provided. The method can include the wireless communication device determining, at the master radio, a transmission power of the master radio. The method can further include the wireless communication device providing information indicative of the transmission power of the master radio from the master radio to the slave radio. The method can additionally include determining, at the slave radio, an allowable transmission power for the slave radio. A sum of the allowable transmission power and the transmission power of the master radio may not exceed the total transmission power limit.

    Abstract: An interface circuit in a device, e.g., an access point, may perform link adaptation. During operation, the interface circuit may provide a wake-up frame, e.g., a LP-WUR packet, associated with a channel in a band of frequencies, where the wake-up frame is intended for a wake-up radio in a recipient device. Then, the interface circuit may receive, from the recipient device, feedback information associated with a second channel in a second band of frequencies, where the feedback information is associated with a main radio in the recipient device. Based at least in part on the feedback information, the interface circuit may estimate one or more communication metrics associated with the channel in the band of frequencies. Moreover, based at least in part on the one or more communication metrics, the interface circuit may determine a data rate for use in communication via the channel in the band of frequencies.
