Abstract

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.
