Abstract: Methods, computer readable media, and wireless apparatuses are disclosed for a TXOP duration field disable setting in a HE preamble, such as HE-SIG-A. An apparatus of a wireless device can include processing circuitry configured to decode a HE PPDU received from a second wireless device, the HE PPDU including a first TXOP duration field in a PHY portion of the HE PPDU. The processing circuitry can detect whether the TXOP duration field includes a disable flag based on bit values of the TXOP duration field. The disable flag can indicate absence of duration information in the TXOP duration field. Upon detecting the disable flag, a response HE PPDU can be encoded for transmission to the second wireless device. The response HE PPDU can include a second TXOP duration field with a disable flag within a PHY portion of the response HE PPDU.

Abstract: For example, an apparatus configured to cause a first Wake-Up Radio (WUR) wireless communication station (STA) to exchange a request frame and a response frame with a second WUR STA to set up a plurality of WUR parameters of a WUR mode at which the first WUR STA is to transmit one or more WUR wake-up frames configured for reception by a Wake-Up Receiver (WURx) of the second WUR STA, wherein the request frame is from the second WUR STA to the first WUR STA, and the response frame is from the first WUR STA to the second WUR STA in response to the request frame; to transmit an unsolicited update frame to the second WUR STA to update one or more WUR parameters of the plurality of WUR parameters; and to receive an Acknowledgement (Ack) frame from the second WUR STA to acknowledge the unsolicited update frame.

Abstract: Methods, apparatus, and computer-readable media are described to encode, by a first station, duty cycle timing for transmission to a second station via a primary connectivity radio. A wake-up radio (WUR) receiver (WURx) is enabled to receive a transmission based upon the duty cycle timing of the WURx when the primary connectivity radio is in a doze state from a perspective of the second station. A wake-up packet, received from the second station, is decoded and received by the WURx. The WURx receives a WURx transmission when in an WURx awake state. The primary connectivity radio is enabled based upon decoding the wake-up packet.

Abstract: A transmitter/receiver pair may estimate a first channel interference caused during the spatial reuse phase by the transmitter/receiver pair to other transmitter/receiver pairs over a channel. A second channel interference experienced by the transmitter/receiver pair may be estimated during the spatial reuse phase by the transmitter/receiver pair from the other transmitter/receiver pairs. An interference margin may be estimated for the channel based on the first and second channel interferences. The interference margin may be announced to the other transmitter/receiver pairs in frame. The interference margin may then be complied with while communicating over the channel in order to control the interference.

Abstract: Logic to “loosely” manage synch frame transmissions in a synch network via the devices synched to the network that implement the logic. Logic may distributedly adjust the frequency of attempting synch frame transmissions without estimating the size of the neighborhood. Logic in devices of a synch network to let each device maintain a Transmission Window (TW). Logic to determine the frequency of attempting synch frame transmissions based upon the TW. Logic to increase TW if the device detects a synch frame transmission. Logic to decrease TW if the device successfully transmits a synch frame. Logic to balance power consumption and discovery timing by adjusting the decrease in TW responsive to a synch transmission in relation to the increase in TW responsive to detection of a synch transmitted by another device.

Abstract: Systems, apparatus, and methods to provide an indication of frequency resource unit (RU) allocation from a wireless access point (AP) to one or more station devices (STA) are disclosed. The AP may be configured to generate a protocol data unit including a high efficiency wireless (HEW) preamble that indicates the RU allocation corresponding to each of the STA. The indication of the RU allocation for each of the STA, as disclosed herein, may be encoded in fewer bits than providing a bitmap of the RU allocation for each of the STA. A predetermined RU pattern may be used to map RU (e.g., 26 tone units, 52 tone units, etc.) to a RU allocation index. This RU allocation pattern may be efficiently communicated to each of the STAs in the HEW preamble of the protocol data unit.

Abstract: This disclosure describes methods, apparatuses, and systems related to signaling for concurrent operation and/or cancellation capabilities for termination of concurrent operations on networks (e.g., NAN, WLAN networks). In some implementations, systems and methods are provided for handling of time blocks that partially overlaps with the concurrent operations.

Abstract: The disclosure describes systems and methods for updating multicast wakeup schedules in devices in a mesh network such as a neighborhood area network (NAN) multicast service group (NMSG). The systems and methods enable meshed devices to send and receive routing control messages amongst themselves in accordance with a centralized update protocol, a distributed update protocol, or a hybrid update protocol which is a combination of the centralized and distributed update protocols.

Abstract: Embodiments for an access point (AP), station (STA) and method for communication are generally described herein. An access point (AP), configurable to operate in a basic service set (BSS), the apparatus comprising memory. The AP further comprising processing circuitry coupled to the memory. The processing circuitry configured to encode a physical layer convergence procedure (PLCP) protocol data unit (PPDU) for transmission to stations operable in the BSS. The PPDU may comprise a media access control (MAC) header portion. The processing circuitry may encode signaling in the MAC header portion of the PPDU that defines a spatial reuse restriction and the spatial reuse restriction may restrict spatial reuse by stations operating in a BSS that is different from the BSS of the AP. In an embodiment, processing circuitry coupled to the memory may encode the spatial reuse restriction in an HE-A control field of the MAC header portion.

Abstract: Embodiments of a LP-WUR (low-power wake-up radio) wake-up packet acknowledgement procedure are generally described herein. A first wireless device encodes for transmission of a wake-up packet of a LP-WUR to a second wireless device, the wake-up packet to wake up a WLAN (wireless local area network) radio of the second wireless device. Upon decoding a response frame from the second wireless device received during a predefined time period: the first wireless device encodes for transmission of a data packet to the WLAN radio of the second wireless device. Upon failing to receive the response frame from the second wireless device during the predefined time period: the first wireless device encodes for retransmission of the wake-up packet to the second wireless device.
