Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a first wireless device to select a channel to a second wireless device among a set of channels to the second wireless device shared by a set of wireless devices of the wireless network, and further transmit data to the second wireless device over the selected channel. The first wireless device can perform a measurement to determine a channel occupancy during a measurement period for a channel, wherein the measurement period includes a plurality of periodic transmission durations. The first wireless device can select a channel that is less occupied indicated by the channel occupancy of the channel. The first wireless device can further transmit data to the second wireless device over the selected channel in a transmission period after the measurement period.

Abstract: An interface circuit in a recipient electronic device (such as a cellular telephone) may provide preference-indication information for an electronic device (such as an access point). Notably, the recipient electronic device may compute preference-indication information associated with the recipient electronic device, where the preference-indication information indicates whether the recipient electronic device prefers that the electronic device use downlink (DL) multi-user (MU) MIMO transmissions when communicating with the recipient electronic device. Then, the recipient electronic device may provide the preference-indication information in a packet or a frame associated with the electronic device. In some embodiments, the recipient electronic device determines a trigger event (such as measuring a motion indication), and the computing may be selectively performed based at least in part on the trigger event. Moreover, the preference-indication information may include additional information that was used by the recipient electronic device to compute the preference indication of the recipient electronic device.

Abstract: Some embodiments include an apparatus and method for a mobile access point (AP) station that operates in an always-on soft AP mode where a station is associated with the mobile AP station, and switch back to operate as a station in an infrastructure mode with an AP. For example, in an always-on soft AP mode, the mobile AP station may implement a target wake time (TWT) responder power save mode feature. The mobile AP station may maintain a wake window after a beacon to enable unassociated devices to associate; establish a broadcast TWT schedule for unassociated TWT-capable devices to associate; schedule TWT for associated devices; go to sleep outside of the scheduled TWT of the associated devices; and switch back to infrastructure mode to perform as a station and maintain a connection with an AP.

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.

Abstract: Methods, systems, and apparatus are presented for providing enhanced scheduling requests, e.g., in an IEEE 802.11 network. A client station (STA) may determine one or more minimum quality of service (QoS) metrics for supporting an application being implemented by the STA, and may determine minimum scheduling parameters to be implemented by an access point (AP) to achieve the minimum QoS. The STA may transmit to the AP a specific scheduling request indicating the minimum scheduling parameters. In response, the AP may schedule communication resources for the STA in accordance with the minimum scheduling resources.

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.

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: Some embodiments enable low power mode for wireless local area network (WLAN) subsystem of an electronic device to improve power usage at the electronic device and increase response time of the WLAN subsystem to prioritized application(s). For example, a method includes enabling a sleep mode of the WLAN subsystem of the electronic device. The electronic device maintains a connection with an access point of a wireless network during the sleep mode. The method further includes receiving a request from an application to communicate with the wireless network. The application is included in a list of prioritized applications. In response to determining that a metric associated with the sleep mode does not exceed a power budget, the sleep mode of the WLAN subsystem is suspended and the communication between the application and the access point of the wireless network is enabled (after the suspension of the sleep mode).
