Abstract: Embodiments of a high efficiency subchannel selective transmission (HE SST) access point (AP) and an HE SST station (STA) are generally described herein. The HE SST AP may determine a temporary primary channel for an HE SST STA. The HE SST AP may communicate with the HE SST STA in a plurality of channels that includes the temporary primary channel and further includes a primary channel. The HE SST AP may determine trigger-enabled target wake time service periods (TWT SPs) for exchange of frames between the HE SST AP and the HE SST STA on the temporary primary channel. The trigger-enabled TWT SPs may be determined to not overlap with target beacon transmission times (TBTTs) at which beacon frames that include delivery traffic indication maps (DTIMs) are to be sent on the primary channel by the HE SST AP.

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: 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: 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: Computer readable media, methods, and apparatuses to determine whether to respond to a frame based on a network allocation vector. An apparatus of a station comprising memory and processing circuitry coupled to the memory is disclosed. The processing circuitry is configured to: decode a frame comprising a first duration and a first transmitter address, if the frame is a trigger frame or a multi-user request-to-send (MU-RTS) frame from a master station of a basic service set (BSS), respond to the trigger frame or the MU-RTS frame if the trigger frame or MU-RTS frame comprises a NAV indicator that indicates not to consider a network allocation vector (NAV). The indication may be an indication in a physical header or an indication in a media access control header.
