    Abstract: A wireless communication device (UE) includes a cellular processor configured to conduct wireless communications according to a first radio access technology (RAT) in a first frequency band and in a second frequency band, wherein the first RAT is a cellular RAT, the first frequency band is in an unlicensed spectrum, and the second frequency band is in a licensed spectrum. In some embodiments, the apparatus includes a wireless local area network (WLAN) processor configured to conduct wireless communications according to a second RAT in the first frequency band. In some embodiments, the cellular processor and the WLAN processor are configured to couple to a common antenna for communications in the first frequency band. In some embodiments, the cellular processor may notify the WLAN processor when it is scanning and/or when it is assigned secondary component carriers in the first frequency band. In some embodiments, the WLAN processor may notify the cellular processor when it is transmitting. In some embodiments, the WLAN processor and/or the cellular processor may perform one or more actions in response to such notifications to improve coexistence in the first frequency band.

    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: 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.

    Abstract: An interface circuit in an electronic device (such as an access point) may provide a group wake-up packet to a group of recipient electronic devices in a set of recipient electronic devices. During operation, the interface circuit may select the group in the set of recipient electronic devices, where the group includes at least one of the recipient electronic devices. Then, the interface circuit may provide the group wake-up packet for the recipient electronic devices in the group with information that specifies that a subset of the recipient electronic devices in the group transition from a low-power mode. For example, the information may include a bitmap that specifies the subset and an identifier of the group. Note that the electronic device may dynamically define the group. Alternatively, the recipient electronic devices in the group may be static.
