Abstract: In order to improve the quality of a telephone call communicated over a wireless local area network (WLAN), an electronic device (such as a cellular telephone) may obtain one or more performance metrics based on communication with another electronic device (such as an access point) via a connection in the WLAN. For example, the electronic device may receive the one or more performance metrics from the other electronic device and/or may determine the one or more performance metrics based on the performance of the communication. Then, the electronic device may compare the one or more performance metrics with an interference criterion. If the interference criterion is met, the electronic device may perform a remedial action, such as selectively discontinuing use of the WLAN to communicate the telephone call for a time interval. Otherwise, the electronic device may continue using the WLAN to communicate the telephone call.

Abstract: Methods and apparatus to mitigate interference among multiple wireless subsystems of a wireless communication device are described. A host processor obtains configurations for a plurality of wireless subsystems and evaluates whether potential or actual coexistence interference exists between two or more of the wireless subsystems. The host processor provides configuration information and link quality reporting parameters to and obtains link quality reports from at least two wireless subsystems. When link quality for at least one wireless subsystem fails a set of link quality conditions, the host processor adjusts data requirements for applications that communicate through one or more of the wireless subsystems and/or adjusts radio frequency operating conditions for one or more of the wireless subsystems to mitigate interference among the wireless subsystems.

Abstract: In order to facilitate communication between an electronic device and another electronic device, the electronic device determines communication-quality metrics for a first connection in a wireless network based on received information from the other electronic device. Then, the electronic device calculates an overall communication-quality indicator for the first connection based on at least some of the communication-quality metrics. Moreover, the electronic device dynamically adapts the communication with the other electronic device based on the overall communication-quality indicator. For example, the electronic device may establish a second connection in a cellular-telephone network and may use the second connection to communicate with the other electronic device. Alternatively, the electronic device may provide the overall communication-quality indicator to the other electronic device and may at least partially transition the communication from the second connection in the cellular-telephone network to the first connection in the wireless network.

Abstract: Methods and apparatus for adaptively adjusting receiver operation for e.g., power optimization. In one embodiment, operation during diversity operation is adaptively adjusted. Diversity techniques consume significantly more power than non-diversity operation. However, the performance gain from receiver diversity is not always predictable. Consequently, in one embodiment, a device evaluates the overall performance gain contributed by diversity operation and, where the performance gain is insignificant or inadequate, the device disables diversity operation. In one implementation, the device can operate in a static single antenna mode, a dynamic single antenna mode and a dynamic multiple antenna mode.

Abstract: This application relates to electronic devices configured to connect to a wireless local area network and communicate using a trigger-based access mechanism. An access point is configured to manage the wireless local area network. The access point includes a processing subsystem configured to select a channel associated with a communications medium for communicating with the set of electronic devices. The processing subsystem is also configured to monitor the channel to detect interference from radio frequency sources not connected to the wireless local area network, receive channel information for at least one additional channel associated with the communications medium from the electronic devices, and configure an interface circuit of the access point to communicate with the set of electronic devices on a new channel based, at least in part, on the channel information. Each electronic device can be configured to collect the channel information and transmit the channel information to the access point for analysis.

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: Embodiments relate to apparatus, systems, and methods for reception of calls on a mobile device that includes Wi-Fi and cellular radios. The mobile device may be configured to establish communication on a Wi-Fi network with a cellular carrier. The mobile device may further be configured to register a first IP address with an IMS server for the Wi-Fi network communication and register a second IP address with the IMS server for the cellular network communication (or register different ports of a single IP address with Wi-Fi and cellular). Upon occurrence of a mobile terminating call from the cellular carrier, the mobile device may receive an incoming call notification on one or both of the Wi-Fi network using the first IP address and the cellular network using the second IP address.

Abstract: An electronic device that determines a transmission schedule is described. This electronic device may include an interface circuit that communicates with a recipient electronic device. During operation, the electronic device may receive a frame with scheduling-request information that is associated with the recipient electronic device. The scheduling-request information may include a buffer status report for persistent traffic, and the frame may be compatible with an IEEE 802.11 communication protocol. For example, the frame may include a scheduling-request management frame. Alternatively, the frame may include a data frame and the scheduling-request information may be included in a media access control (MAC) frame header, such as a high-efficiency (HE) variant high-throughput (HT) control header. Then, the electronic device may determine the transmission schedule based at least in part on the scheduling-request information.

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.
