Abstract: During operation, an interface circuit in an electronic device may receive, from a second electronic device (such as an access point in a WLAN), an uplink trigger frame that may specify an access category. In response to the uplink trigger frame, the electronic device may first include data associated with the specified access category in one or more frames, and then may transmit the one or more frames to the second electronic device. Moreover, when all the data associated with the specified access category has been transmitted or when there is no data associated with the specified access category, and when there is leftover time in an allocation associated with the uplink trigger frame, the interface circuit may transmit the one or more frames to the second electronic device with additional data associated with another access category that is different from the specified access category.

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: Methods for performing a ranging procedure according to the non-trigger-based protocol may include negotiating timing parameters associated with the ranging procedure, performing a ranging measurement, and transmitting/receiving, after completion of the ranging measurement, a message announcing initiation of another ranging measurement. The timing parameters may indicate a time window in which an initiating device can initiate a subsequent ranging measurement and the message announcing initiation of the second ranging measurement may be received during the time range specified. Timing parameters may indicate a responding device's required minimum and maximum time between ranging measurements. Additional parameters may indicate an initiating device's required minimum and maximum time between ranging measurements. A power savings mode may be entered after the first ranging measurement and during at least a portion of a time period specified by the parameters.

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.

Abstract: This disclosure relates to techniques for performing ranging wireless communication including prioritization. A first wireless device may transmit a request for ranging services to a second wireless device. The first wireless device may transmit an indication of a ranging priority to the second wireless device. The second wireless device may determine a granted ranging priority. The first and second wireless device may perform ranging communication according to the granted ranging priority.

Abstract: An access point selects a channel access policy for an electronic device in a wireless local area network (WLAN). During operation, an interface circuit of the access point receives a channel access preference from the electronic device. The channel access preference includes: a multi-user trigger-based channel access technique, a single-user contention-based channel access technique, or both. The interface circuit selects the channel access policy for the electronic device based, at least in part, on the received channel access preference. The channel access policy can also be selected based at least in part on a communication performance metric associated with communication in the WLAN. The interface circuit communicates the selected channel access policy to the electronic device, which subsequently accesses a communication channel and communicates packets with the access point in accordance with the channel access policy.

Abstract: A recipient electronic device that provides an acknowledgment is described. This recipient electronic device may include a main radio and a wake-up radio (WUR) that at least selectively transitions the main radio from a lower-power mode to a higher-power mode in response to a wake-up frame. During operation, the WUR receives a wake-up frame associated with an electronic device, e.g., a second or a sending device. Then, the WUR provides, in response to the wake-up frame, the acknowledgement intended for the electronic device. The wake-up frame may specify that an acknowledgement from the recipient electronic device to the electronic device is expected. For example, the wake-up frame may specify that the acknowledgement is communicated by the recipient electronic device using the WUR in the recipient electronic device. Moreover, the WUR may provide the acknowledgment while the main radio is in the lower-power mode.

Abstract: In some embodiments, one or more wireless stations operate according to Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. In a NAN system, multiple NAN devices may operate with one another in the form of a NAN cluster to facilitate communications processes. Some embodiments of the disclosure relate to systems and methods for one or more wireless device (e.g., NAN devices) to transition into a cluster (e.g., a NAN cluster). In particular, wireless devices may be further organized into a data cluster (e.g., a NAN data cluster) within a cluster, which may be usable to facilitate the transitioning of a group of connected wireless devices (e.g., data clusters) between clusters.

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: In some embodiments, one or more wireless stations operate according to Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. In a NAN system, multiple NAN devices may operate in conjunction in the form of a NAN cluster to facilitate communications processes, and may be further organized into “NAN data clusters” within NAN clusters. NAN data clusters may use a common base channel to convey communications among member NAN devices. Embodiments herein provide mechanism by which a base channel may be determined, modified, and/or distributed among NAN devices operating in a NAN data cluster.
