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:
The embodiments set forth herein disclose techniques for enabling a user device to seamlessly establish a secure, high-bandwidth wireless connection with a vehicle accessory system to enable the user device to wirelessly stream user interface (UI) information to the vehicle accessory system. To implement this technique, a lower-bandwidth wireless technology (e.g., Bluetooth) is used as an initial means for establishing a Wi-Fi pairing between the user device and the vehicle accessory system. Wi-Fi parameters associated with a Wi-Fi network provided by the vehicle accessory system can be communicated to the user device using the lower-bandwidth wireless technology. A secure Wi-Fi connection can then be established between the user device and the vehicle accessory system using the provided Wi-Fi parameters. The embodiments also disclose a technique for enabling the user device to automatically reconnect with the vehicle accessory system in a seamless manner (e.g., when returning to a vehicle).
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.
Abstract:
This document describes multicast communication between wireless devices. A scheduling frame may be wirelessly transmitted by a wireless device. The scheduling frame may include a multicast address indicating a group of intended receiving devices for a payload frame. The scheduling frame may further include scheduling information indicating an order for the group of intended receiving devices to transmit acknowledgement information for the payload frame. A payload frame may also be wirelessly transmitted by the wireless device. The payload frame may include payload information intended for the group of intended receiving devices. Additionally, acknowledgement frames may be wirelessly received by the wireless device from at least a subset of the group of intended receiving devices. The acknowledgement frames may be received according to the order indicated in the scheduling information.
Abstract:
A host device may include a wireless interface for communications, a memory, and a processor coupled to the memory and to the wireless interface. The host device may receive, via the wireless interface, an advertisement message from a client device. The advertisement message may include an identifier associated with the client device and a request for communication of data from a cloud-based service. Responsive to the advertisement, the host may send the identifier to the cloud-based service. The host may receive from the cloud-based service, a proxy indication of available data associated with the client. Responsive to receiving the proxy indication of available data, the host may provide, via the wireless interface, a connection request including a client indication of the available data from the cloud-based service to the client. After receiving the available data from the cloud-based service, the host device may send the available data to the client.
Abstract:
Circuits, methods, and apparatus that react to brownout or near brownout conditions and mitigate complications that may result. Examples may turn off one or more circuits, such as a Wi-Fi transceiver when a brownout condition is reached or neared. Other examples may provide circuits, methods, and apparatus that proactively avoid brownout conditions. These examples may detect that a brownout condition may occur and take steps, such as Wi-Fi traffic shaping, to avoid them. Still further examples may react to brownout or near brownout conditions one or more times, then preemptively act to avoid further brownout conditions.
Abstract:
A wireless local area network (WLAN) station (STA) reports, with a medium access control (MAC) frame, a buffer status of an urgent traffic identifier (TID) to a second STA. In some embodiments, the second STA is also an access point (AP). The delay in reporting is reduced by providing a buffer status report for the urgent TID in a data frame being transmitted to carry data for a current TID. The buffer status report, in some embodiments, provides the value of the urgent TID. In some embodiments, the buffer status report provides an indication of the amount of data in a buffer corresponding to the urgent TID. In some embodiments, the buffer status report is based on an aggregated measure of more than one buffer with data awaiting transmission. The transmission of the MAC frame, in some embodiments, is unsolicited.
Abstract:
A client device can be configured to identify data to be communicated with a network. In some examples, the client device can determine one or more transient properties of the client device and/or receive a connection request from a host device that is connected to the network, where the connection request comprises one or more connection properties of the host device. In some instances, the client device can also be configured to determine whether the host device is capable of transmitting the data to the network based at least in part on the one or more transient properties of the client device and the one or more connection properties of the host device and/or establish a connection with the host device in accordance with determining that the host device is capable of transmitting the data to the network.
Abstract:
An electronic device communicates frames with an access point (AP) by receiving, from the AP, a frame header that includes information specifying a first set of tones of an OFDMA communication, the first set of tones associated with first resource block subchannels having a first bandwidth used by the AP to transmit a frame payload. The electronic device obtains a second set of tones associated with second resource block subchannels having a second bandwidth that differs from the first bandwidth, and receives the frame payload using the OFDMA communication, the second resource block subchannels, and the second set of tones. Alternatively, an electronic device dynamically switches a channel-access mode when communicating a frame with the AP depending on whether the communication includes a primary 20 MHz channel. In a technique, an MU-PPDU is communicated using a frame via a non-primary 20 MHz channel without using the primary 20 MHz channel.
Abstract:
Passive and active scanning for extended range wireless networking. The choice between legacy and extended range signaling can depend on one or more factors. For passive scanning, an electronic device may transmit a combination of legacy beacons and extended range beacons for network discovery by receiving electronic devices. For active scanning, an electronic device may transmit extended range probe requests in addition to legacy probe requests to discover all of the access points within its transmission range. Responses to probe requests can use extended range, legacy, single user, and/or multi user protocols.
