Abstract: During operation, an electronic device may perform, using a scanning radio, a scan of a band of frequencies, where the scanning radio only receives frames. Then, the electronic device may receive, using the scanning radio, a beacon frame associated with a second electronic device, where the beacon frame includes information associated with operation of a third electronic device in a second band of frequencies. Next, the electronic device may perform, using a data radio, a second scan of the second band of frequencies based at least in part on the information, where the data radio transmits and/or receives second frames, and where the second scan is performed, at least in part, while the scan is performed. Note that the electronic device may not be associated with (or may not have a connection with) the second electronic device and/or the third electronic device.

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).

Abstract: Embodiments provide a technique for enabling a wireless device to operate in a power saving mode without completely cutting off the wireless device from receiving outside communications. The technique includes, at an access point (AP), generating traffic indication map (TIM) information that indicates whether downlink data directed to the wireless device is buffered at the AP. The AP precedes a beacon frame with at least one “lightweight” traffic indication map (TIM) frame that includes the TIM information, which is a subset of the information that is included in the beacon frame. The AP can be configured to transmit the TIM broadcast frame, the beacon frame, and any other frames that include the TIM information during a single transmit opportunity to reduce the number of instances where the wireless device is required to transition from an idle state to a listen state.

Abstract: This disclosure relates to methods for providing detailed basic service set load information in a wireless local area network. A wireless device may receive basic service set load information including one or more of overlapping basic service set channel utilization information, in basic service set channel utilization information for a basic service set, or load history information for the basic service set. The wireless device may select a basic service set with which to associate based at least in part on the load information for the basic service set.

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: An interface circuit in an electronic device (such as an access point) may provide a wake-up-radio (WUR) discovery frame for a recipient electronic device, where the WUR discovery frame includes an operating class of a wireless local area network (WLAN) associated with the electronic device. The operating class may specify a regulatory domain and a channel set of the WLAN. Moreover, the WUR discovery frame may include an index of a channel in the channel set. Furthermore, the WUR discovery frame may include a compressed or a partial identifier associated with the electronic device or the WLAN. The amount of compression may be based at least in part on a communication environment of the electronic device, such as a number of electronic devices, or a number of neighboring WLANs. Thus, the WUR discovery frame may have a variable size or length.

Abstract: One embodiment of the present invention provides a system that facilitates offloading neighbor discovery from a host prior to the host entering Wake on Wireless LAN (WoWLAN) mode. During operation, the system receives a request from a host executing on the processor to enter WoWLAN mode. Next, the system collects a set of active IP addresses on the host. The system then places the apparatus in WoWLAN mode. Next, the system receives neighbor discovery requests from IP addresses external to the host at a networking chip external to the processor. The system then responds to the neighbor discovery requests from the networking chip on behalf of the host and without waking the host from WoWLAN mode for requests destined to IP addresses that are members of the set of active IP addresses. Finally, the system also prevents, at the networking chip, the neighbor discovery requests from waking the host.

Abstract: Embodiments disclosed herein relate to reducing power consumption of an electronic device scanning for wireless communication signals while maintaining or even improving an efficiency of the scanning operations. To do so, the electronic device may include more than one scan core, such as a main core and a receiving core. The receiving core may have limited functionality compared to the main core. For example, the receiving core may only receive wireless signals (including scanning for wireless signals). That is, the receiving core may not support certain operations that consume relative high power that are supported by the main core, such as transmission of signals. In this way, operation of the receiving core, either in place of or in addition to the main core, may reduce power consumption of the electronic device by avoiding high power consuming operations, such as data transmission, while scanning for various signals.

Abstract: Embodiments for performing a fast return to Wi-Fi following completion of a cellular voice call are provided. These embodiments include detecting that a device has switched from communicating over a Wi-Fi interface to communicating over a cellular interface; determining the earliest time that the device can switch back to Wi-Fi; and instituting the switch. In some embodiments, the process of performing a fast return to Wi-Fi is carried out by devices having small form factors, such as smartwatches and other wearables, which may be susceptible to coexistence and peak power problems. The fast return to Wi-Fi embodiments disclosed herein allow a device to perform a voice call over a cellular interface when Wi-Fi calling is not available, and switch over to a Wi-Fi interface immediately upon completion of the voice call in order to conserve battery life, achieve higher data speeds, and avoid high costs associated with cellular data transmissions.
