    摘要： Apparatuses, computer readable media, and methods for uplink sounding in wireless networks are disclosed. An apparatus of a wireless device may include processing circuitry configured to: encode an uplink sounding trigger element (USTE) for one or more stations, the USTE comprising one or more uplink (UL) resource allocations for the one or more stations to transmit one or more uplink sounding referee elements (USREs) to the wireless device. The processing circuitry may be further configured to configure the wireless device to transmit the USTE to the one or more stations, and decode the one or more USREs from the one or more station, wherein the one or more USREs are to be received by the wireless device in accordance with a corresponding resource allocation indicated in the USTE.

    摘要： Embodiments of an access point (AP), station (STA) and method for uplink sounding are generally described herein. The AP may transmit an uplink (UL) sounding trigger frame (TF) that indicates a request to receive UL sounding elements from a group of one or more stations (STAs). The AP may receive UL sounding elements from the STAs in accordance with UL multi-user multiple-input multiple-output (MU-MIMO) reception. The AP may also receive, from at least a portion of the STAs, UL sounding feedback that includes one or more UL sounding transmission parameters used by the portion of the STAs for UL sounding element transmissions. The UL sounding TF may further indicate the portion of the STAs that are to transmit the UL sounding feedback.

    摘要： Apparatuses, methods, and computer readable media are disclosed for sounding using manipulated null data packets (NDP). An apparatus of an wireless device comprising memory and processing circuitry coupled to the memory is disclosed. The processing circuitry may be configured to: encode a null data packet (NDP) announcement (NDP-A) frame, configure the wireless device to transmit the NDP-A frame, and encode a manipulated NDP frame. The processing circuitry may be further configured to configure the wireless device to transmit the manipulated NDP frame, encode a trigger frame comprising resource allocations for one or more stations, and configure the wireless device to transmit the trigger frame. The processing circuitry may decode beamforming feedback frames from the stations, where the beamforming feedback frames are to he received by the wireless device in accordance with the resource allocations, and where the beamforming feedback frames are to comprise feedback for the manipulated NDP frame.

    摘要： System and techniques for multi-phase wireless sounding are described herein. A first set of stations may be selected by an access point from a plurality of stations known to the access point. The access point may then transmit a first sounding request to members of the first set of stations. The access point may receive a sounding report in response to the first sounding request from members of the first set of stations. The access point may then select a second set of stations from the plurality of stations based on the sounding report. This second set of stations is a proper subset of the first set of stations. The access point may then transmit a second sounding request to the second set of stations.
