Abstract: This disclosure describes systems, methods, and devices related to low power wake-up radio beacon signaling. An access point may determine timing information for the transmission of low power wake up radio beacons and send that timing information to a user device. An access point may then send low power wake up radio beacons based on that timing information to a user device, and a user device may receive the low power wake up radio beacons based on the timing information.

Abstract: Described herein are mechanisms to inform a first Neighbor Awareness Networking (NAN) device as to whether or not a second NAN device is connected to a dynamic frequency selection (DFS) master and/or whether the second NAN device is listening to the same DFS master as the first NAN device. In order for NAN client devices to operate in the 5 GHz band and be DFS compliant, all such devices that are communicating in a NAN peer-to-peer manner must either maintain association with a DFS master or must listen to the same DFS master for channel information.

Abstract: Methods, devices, and systems for retransmission of wake-up signals from a first station to a second station over a wireless network are disclosed. In some aspects, a wake-up signal is encoded for transmission to the second station. While the first station is waiting for an acknowledgment of the wake-up signal from the second station, the second station may retransmit the wake up signal and/or encode a packet for transmission to a third station. In some aspects, whether the wake-up signal is retransmitted is based in part, on at least one of whether a number of timeout events for wake-up signals transmitted to the second station exceeds a maximum timeouts threshold, whether a number of wake-up signals transmitted to the second station exceeds a maximum wake-up signals threshold; or whether a maximum predetermined elapsed time since a first wake-up signal was transmitted to the second station is exceeded.

Abstract: A STA and method of providing a subscription policy are provided. The STA determines a subscription policy for a multicast, broadcast or unicast service and provides a policy comprising an indication that indicates active subscription (i.e. group joining is required) or no subscription (i.e. group joining is prohibited) or implicit subscription (i.e. group joining is implicit), dependent on network or subscription conditions. Updates to the policy are transmitted upon one or more thresholds are being reached. Subscribers re-subscribe to the service when the indication switches from implicit subscription to active subscription.

Abstract: This disclosure describes systems, methods, and devices related to enhanced retry count for an uplink (UL) multi-user (MU) transmission. A device may identify a trigger frame received from a first device on a wireless communication channel. The device may determine a quality of service counter associated with an access category. The device may cause to send a frame to the first device based at least in part on the trigger frame. The device may determine an error condition associated with the frame. The device may refrain from incrementing the quality of service counter based on the error condition.

Abstract: Wireless device, method, and computer readable media for multi-user request-to-send and clear-to-send and uplink ACK protection in a high efficiency wireless local-area network are disclosed. A high-efficiency (HE) wireless local-area network (HEW) master device may include circuitry configured to generate a multi-user (MU) RTS packet for a plurality of stations (STAs), the RTS packet to include an indication of an address for each of the plurality of STAs. The circuitry may be further configured to transmit the MU-RTS to the plurality STAs and transmit data to one or more of the plurality of STAs in accordance with at least from the following group orthogonal frequency division multi-user (OFDMA) and multi-user multiple-input multiple-output (MU-MIMO). The circuitry may be configured to receive acknowledgements from the one or more of the plurality of STAs. A HEW device may set a deferral duration in an uplink transmission to enable a HEW master device to send an acknowledgement.
