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： A station (STA), an access point (AP) and method of adjusting for detection of an Overlapping Basic Service Set (OBSS) packet is disclosed. The STA may initiate a counter in response to determining that a BSS packet is to be transmitted. A packet may be detected on the channel and the counter suspended. If the packet is a BSS packet, the counter may be reset and restarted. If the packet is an OBSS packet, the counter may be decremented by a time to detect and determine that the packet is the OBSS packet and subsequently restarted prior to transmitting the BSS packet when the counter reaches 0. The counter may be further decremented by an Inter Frame Space period. If the counter after being decremented is 0, the BSS packet may be transmitted immediately, the counter may not be decremented or may be incremented by a backoff window.

A method may include assigning respective subsets of subcarrier frequencies to a plurality of user devices for communication over a wireless channel. The method may also include transmitting, simultaneously, a channel status request poll to the user devices. Additionally, the method may include determining, based at least in part on a first channel status response received via a first subset of subcarrier frequencies over the wireless channel, that the first channel status response is received from the first user device. Similarly, the method may also include determining a second channel status response is received from a second user device. Furthermore, the method may include determining, based at least in part on the first channel status response and the second channel status response, to schedule simultaneous data communication for the first device and the second device.

摘要： For example, an AP may be configured to set RU allocation information for a user STA in an RU allocation subfield of a user field for the user STA. For example, the RU allocation information for the user STA may indicate an RU allocation for a TB UL transmission from the user STA. For example, the AP may be configured to set a 7-bit UL MCS subfield, for example, after the RU allocation subfield, to indicate a first MCS and a second MCS for the user STA. For example, the first MCS may be assigned to a first UL resource of the RU allocation for the user STA, and the second MCS may be assigned to a second UL resource of the RU allocation for the user STA. For example, the AP may be configured to transmit a trigger frame including the user field for the user STA.

摘要： A client station (STA), when operating in a wireless network, receives data sent by an access point (AP) on a first channel comprising at least one subchannel. During reception of the data on the first channel, the STA monitors channel availability of an additional set of one or more subchannels. In response to a detected availability of at least one newly-available subchannel, the STA sends at least one notification to the AP identifying STA-side availability of the newly-available subchannel(s). The STA subsequently receives data from the AP on the newly-available subchannel(s), which is sent in response to the at least one notification. The AP, when communicating data to the STA, receives the at least one notification from the STA and, in response thereto, initiates data transmission on one or more of the newly-available channel(s).
