摘要： Wireless devices, methods and computer readable media for spatial reuse in a high efficiency wireless local-area network. An apparatus of a HEW station may comprise circuitry. The circuitry may be configured to determine if a plurality of links with a plurality of wireless stations are device-to-device links that indicate that there is a spatial reuse opportunity; and transmit a packet that comprises a spatial reuse indication that there is the spatial reuse opportunity, if the spatial reuse opportunity is indicated. The spatial reuse opportunity may be an uplink orthogonal frequency division multiple access (OFDMA) with the plurality of wireless stations, a downlink OFDMA with the plurality of wireless stations, or a downlink multiple users multiple-input multiple-output (MU-MIMO). The spatial reuse indication may include a margin that indicates how a second HEW station may adjust a transmit power and clear channel assessment to use within the spatial opportunity.

摘要： For example, a non Access Point (AP) (non-AP) station (STA) may be configured to operate in a 40 Megahertz (MHz) operating mode, as a 40 MHz operating non-AP STA, which supports a 40 MHz operating channel width. For example, the 40 MHz operating non-AP STA may be capable to process allocation information from an AP to identify a Resource Unit (RU) or Multiple RU (MRU) (RU/MRU) allocated to the 40 MHz operating non-AP STA within the 40 MHz operating channel width; and to communicate data over the RU/MRU allocated to the 40 MHz operating non-AP STA as part of a wider bandwidth Orthogonal Frequency Division Multiple Access (OFDMA) transmission over a channel bandwidth of at least 80 MHz.

摘要： This disclosure describes systems, methods, and devices related to multi-user uplink channel sounding. A device may determine a channel sounding sequence with one or more access points (APs), wherein the channel sounding sequence comprises a null data packet announcement (NDPA) communicated with at least one of the one or more APs. The device may determine a first group of station devices (STAs) associated with a first basic service set (BSS). The device may cause to send a trigger frame to the first group of STAs to solicit an uplink NDP from each STA of the first group of STAs. The device may identify a first uplink NDP received from a first STA of the first group of STAs. The device may identify a second uplink NDP received from a second STA of a second group of STAs.

摘要： Embodiments of an AP and wake up radio (WUR) non-AP station (STA) are generally described herein. The AP may transmit a WUR packet to wake up a wireless local area network (WLAN) radio of the WUR non-AP STA. A non-WUR portion of the WUR packet may include legacy fields and a BPSK mark to spoof high throughput (HT) devices receiving the WUR packet. The AP may transmit the BPSK mark in a channel that includes a lower guard band, a transmission bandwidth, and an upper guard band. The AP may encode the BPSK mark in accordance with: on-off keying (OOK) modulation in a center portion of the transmission bandwidth; and orthogonal frequency division multiplexing (OFDM) in a remaining portion of the transmission bandwidth that excludes the center portion.
