Abstract: A legacy WiFi communication may contain information to permit a receiver to know of the presence of a parallel new band (NB) communication, and to receive that information in time to know how to receive the NB communication. In various embodiments, this information may be contained in the L-SIG, RL-SIG, and/or HE-SIG-A subfields of a single user PPDU, or in the L-SIG, RL-SIG, HE-SIG-A, and/or HE-SIG-B subfields of a multi-user PPDU.

Abstract: An apparatus, computer readable medium, and method for overlapping basic service set (OBSS) indication in a high-efficiency wireless local-area network (HEW). An apparatus of a high-efficiency wireless local-area network device is disclosed. The apparatus including transceiver circuitry and processing circuitry configured to receive a frame and determine whether the frame is a frame transmitted from a basic service set (BSS) or a frame transmitted from an OBSS based on one or more media access control (MAC) addresses of the frame. The MAC address may include an indication of a BSS of the HE wireless device. If the HE wireless device is an access point, then a second part of the MAC address may be a predetermined pattern, the second part of the MAC address may be a formula applied to a first part of the MAC address, or an individual/group bit of the MAC address may be set.

Abstract: This disclosure describes systems, methods, and devices related to wake-up radio (WUR) advertisement channels. A device may include a wake-up receiver (WURx) and a primary connectivity radio. The device may determine a wake-up radio (WUR) discovery subchannel for WUR advertisement. The WUR discovery subchannel may be associated with a channel of a frequency band. The device may generate a WUR discovery frame comprising a WUR advertisement. The device may transmit, by the WURx, the WUR discovery frame to a second device using the WUR discovery subchannel. The device may identify a response from the second device indicating an acknowledgment of the WUR discovery frame.

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: Methods, computer readable media, and wireless apparatuses are disclosed. The apparatuses including processing circuitry configured to: associate with a master station, decode a frame, where the frame comprises a first duration and a transmitter address and determine that the frame is an intra basic service set (Intra-BSS), an inter (Inter-BSS), or an unclassified frame, where the unclassified frame is the Intra-BSS frame or the Inter-BSS frame. The processing circuitry may be further configured to set an Intra-BSS network allocation vector (NAV) to the first duration if the first duration is longer than a current duration of the Intra-BSS NAV and the frame is determined to be the intra-BSS frame and set the second NAV to the first duration if the first duration is longer than a current duration of the second NAV and the frame is determined to be the inter-BSS frame or the unclassified frame.

Abstract: The disclosure generally relates to a method, system and apparatus to communicate in a neighbor awareness network (NAN) cluster. In an exemplary embodiment, the disclosure provides dynamic wakeup frequency in one or more mobile devices in a NAN cluster of mobile devices. The dynamic wakeup frequency may include additional device awake times in between consecutive NAN discovery windows (DWs). The additional awake periods may be prompted by a layer higher than the NAN/MAC layer. The additional awake periods may be prompted by the NAN/MAC layer itself in response to observing a larger volume of messages exchanged between the mobile device and other devices in the NAN cluster.
