    摘要： A transmitter/receiver pair may estimate a first channel interference caused during the spatial reuse phase by the transmitter/receiver pair to other transmitter/receiver pairs over a channel. A second channel interference experienced by the transmitter/receiver pair may be estimated during the spatial reuse phase by the transmitter/receiver pair from the other transmitter/receiver pairs. An interference margin may be estimated for the channel based on the first and second channel interferences. The interference margin may be announced to the other transmitter/receiver pairs in frame. The interference margin may then be complied with while communicating over the channel in order to control the interference.

    摘要： The present disclosure relates to computer-implemented systems and methods for facilitating simultaneous poll responses. 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： 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.
