The processing circuitry may be configured to decode a first portion of a physical layer convergence procedure (PLCP) protocol data unit (PPDU), and configure the station to transmit a frame, if the PPDU is an overlapping basic service set (OBSS) PPDU, and a receive power of the PPDU is below an overlapping power detect level. An apparatus of an access point comprising processing circuitry is disclosed. The processing circuitry may be configured to encode a PPDU comprising a basic service set identifier of the access point, and encode the PPDU to indicate spatial reuse (SR) delay, SR restricted, or SR not permitted.

Abstract: Embodiments of a station (STA), access point (AP) and method for determination of transmit power for spatial reuse are generally described herein. The STA may detect, in the channel, an overlapping basic service set (OBSS) physical layer convergence procedure protocol data unit (PPDU) from an OBSS AP. The STA may determine, based at least partly on an ESS color parameter included in the OBSS PPDU, whether the OBSS AP is included in the ESS network. The STA may determine an OBSS power threshold based at least partly on whether the OBSS AP is included in the ESS network. The STA may determine, based at least partly on a comparison between the OBSS power threshold and a received power of the OBSS PPDU, whether to transmit an uplink PPDU to the BSS AP in the channel during the TXOP.

An apparatus of a wireless device is disclosed. The apparatus comprises processing circuitry configured to contend for access to a wireless medium of a channel with a first access category (AC), where the first AC comprises a first transmission opportunity (TXOP) limit, a first contention window minimum (CWmin), a first contention window maximum (CWmax), and a first arbitration inter-frame space (AIFS) number (AIFSN), and where the wireless device is to contend for the wireless medium in accordance with the first CWmin, the first CWmax, and the first AIFSN.

Abstract: This disclosure describes methods, apparatuses, and systems related to network allocation vectors. A device is disclosed that may determine a first length of time corresponding to a first spatial reuse transmit opportunity (SR-TxOP) time period. The device may determine a second length of time corresponding to a transmit opportunity (TxOP) time period that starts when a request to send (RTS) frame is transmitted and ends after the first length of time ends. The device may cause to transmit the RTS frame, over the channel, to a first device. The device may determine that a clear to send (CTS) frame is received from the first device, the CTS frame comprising a first duration field equal to having a third length of time corresponding to a second transmission opportunity (SR-TxOP). The device may determine that the third length of time corresponds to a length of time between when the CTS frame was transmitted and when the first length of time ends. The device may determine that the third length of time is less than the second length of time. The device may cause to transmit a CTS to self frame, over the channel, comprising a second duration field equal to having a fourth length of time, wherein the fourth length of time corresponds to a length of time between when the CTS to self frame is transmitted and when the first length of time ends.

Abstract: Embodiments of a station (STA) and method for communication on primary and secondary channel resources are generally described herein. The STA may transmit a grant frame to indicate a transmission of a data payload by the STA during a grant period. The grant frame may indicate whether the data payload is to be transmitted on primary channel resources or on secondary channel resources. The STA may transmit the data payload to a destination STA on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources. The grant frame may be transmitted on the primary channel resources and on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources.

Abstract: Embodiments for an access point (AP) and method for communication in a basic service set (BSS) of a management domain are generally described herein. The AP may be configured to maintain a list of BSSs that belong to the management domain and retrieve, for a station (STA) configured to perform spatial reuse over overlapping basic service set (OBSS) physical layer convergence protocol (PLCP) protocol data units (OBSS PPDUs) belonging to OBSSs from the management domain, at least one parameter for a spatial reuse rule that proportions overlapping basic service set packet detection levels (OBSS_PD) and transmit power (TxPower) levels for the STA. In an embodiment, the AP may retrieve, for a STA configured to perform spatial reuse over OBSS PPDUs not belonging to OBSSs from the management domain, default parameters for a spatial reuse rule that proportions OBSS_PD and TxPower levels for the STA and encode, for transmission to the STA belonging to the OBSSs from the management domain, an indication of the at least one parameters, and encode, for transmission to the STA not belonging to OBSSs from the management domain, an indication of the default parameters.

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 (PHY) 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.
