Abstract: Methods for performing negative acknowledgements (NACKs) in a Wi-Fi based network may include a wireless device receiving, from a neighboring wireless device, a transmission schedule associated with receipt of data packets from the neighboring wireless device. The transmission schedule may include a timeout period associated with transmission of the data packets and/or a start time of the transmission schedule. The method may also include the wireless device determining an error condition associated with the data packets. The error condition may be, for example, non-receipt of any packet (e.g., data packets and/or non-data packets) prior to expiration of the timeout period and/or detection of a gap in sequence numbers associated with the data packets. The method may further include the wireless device, based on the error condition, transmitting a NACK. The NACK may be (or include) a negative block ACK (N-BA) bitmap indicating which data packets were not successfully received.

Abstract: An access point may receive, from a set of electronic devices, one or more buffer status reports that indicate that at least a subset of the electronic devices have uplink data associated with one or more access categories. In response, the access point may create a group of uplink virtual queues for one or more electronic devices in the subset based on the one or more buffer status reports, where a given uplink virtual queue corresponds to a particular access category and a given electronic device. The access point may start one or more backoff counters with a one-to-one correspondence to uplink virtual queues in the group of uplink virtual queues. When a backoff counter for the given uplink virtual queue reaches zero, the access point may transmit a trigger frame to an electronic device in the subset that corresponds to the given uplink virtual queue.

Abstract: In order to reduce the power consumption associated with waking and receiving beacons, a current listening device in a group of electronic devices wakes and scans for a beacon from another electronic device (such as an access point) using a wireless-local-area-network (WLAN) communication protocol (such as Wi-Fi®). Then, the current listening device transmits information associated with the beacon to the group of electronic devices using a second communication protocol (such as Bluetooth® Low Energy), which is different than the WLAN communication protocol and has a lower power consumption. Moreover, the current listening device receives, using the second communication protocol, a sequence of responses from the group of electronic devices indicating that the information was received, wherein the responses from different electronic devices are received at different times. For example, the responses may be received in a predefined order and/or in round-robin fashion for the group of electronic devices.

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: 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: 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 define a contention-free period associated with a communications medium utilized by the wireless local area network. During the contention-free period, the access point allocates transmission opportunities to each of a number of electronic devices by transmitting trigger frames to the electronic devices via the communications medium. Each trigger frame can be directed to a particular electronic device and indicates to that electronic device that the current transmission opportunity has been allocated to that electronic device to transmit data (e.g., frames) to the access point via the communications medium. The access point implements an algorithm for allocating two or more transmission opportunities within a contention-free period to two or more corresponding electronic devices.
