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: Devices and methods of limiting wideband STA communication are generally described. The STA receives, over a primary channel, a wakeup frame containing an indication of a SP or CBAP to acquire a wideband TXOP over a wide bandwidth channel including the primary channel and a secondary channel and a control trailer having an indication of the wide bandwidth channel. Prior to the SP/CBAP, the STA opens reception from the primary channel to the wide bandwidth channel. The STA then communicates with another STA over the wide bandwidth channel and subsequently reduces reception from the wide bandwidth channel to the primary channel. The wakeup frame originates from an AP/PCP or the other STA, and contains fields indicating the wakeup frame length and SP or a sensing time length prior to the CBAP.

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: 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: Apparatuses, computer readable media, and methods for scheduling trigger frames in a high-efficiency wireless (HEW) local-area network are disclosed. An apparatus of a HEW master station is disclosed. The HEW master station includes transceiver circuitry and processing circuitry configured to transmit a random access trigger frame (TF-R) to a plurality of HEW stations, and receive resource requests from one or more of the plurality of HEW stations in response to the TF-R. The transceiver circuitry and processing circuitry is further configured to transmit an indication when a trigger frame is to be transmitted. The trigger frame is to comprise resource allocations in response to the resource requests. An apparatus of a HEW station may enter a power save mode until a time when a trigger frame is scheduled that includes resource allocations in response to resource requests transmitted to a master station from the HEW station.

Abstract: An apparatus of a first high-efficiency (HE) access point (AP) or station for spatial reuse is the disclosed. The apparatus includes processing circuitry configured to: decode a first portion of a first packet; and if the first portion indicates the first packet was transmitted by a second HE AP or station and that the first packet is an overlapping basic service set (OBSS) packet, then if a preamble detect energy is below a threshold, cause to be transmitted a second packet simultaneously with a portion of the first packet after the first portion. The processing circuitry may be configured to determine the first portion was transmitted by the second HE AP or station if a field in a physical (PRY) header or a second field in a media access control (MAC) header indicate the first packet was transmitted by the second HE AP or station.
