    Abstract: An access point establishes target wakeup times (TWTs) with one or more associated electronic devices in a WLAN. The access point transitions to a power-saving mode outside of the one or more TWTs. The access point maintains synchronization with the one or more electronic devices, during at least a first TWT in the one or more TWTs, by transmitting, to the one or more electronic devices, a TWT beacon that includes, or in conjunction with, synchronization information. Alternatively or additionally, during at least the first TWT, the access point transmits a multi-user trigger frame that includes the synchronization information to the one or more electronic devices. In response to the multi-user trigger frame, the access point receives data frames from the one or more electronic devices, transmits one or more acknowledgments, and transitions into the power-saving mode during a remainder of at least the first TWT.

    Abstract: 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, NAN devices may operate to establish a datapath and multiple NAN devices may operate with one another in the form of a NAN cluster to facilitate communications processes. Portions 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, having established a datapath, 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 access point (AP) in a wireless local area network (WLAN) uses a protocol to determine frequency/time resource allocations of resource units (RUs) in parallel with data transfer to and from WLAN stations (STAs). The AP generates a sounding table associating STAs with RUs for uplink (UL) and downlink (DL). The AP processes the sounding table to create a channel map table and then the AP allocates particular RUs to particular STAs. The STAs then receive and transmit data from and to the AP over the allocated RUs. This approach achieves good throughput while reducing the use of signaling and pilot overhead associated with channel sounding. To avoid interruption of ongoing transmissions, a newly arriving STA is grouped and sounded with other STAs. The protocol includes a joint sounding and data epoch followed by a determination of the channel map table.

    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 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.

    IPC: H04W52/02

    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.
