Abstract

Embodiments of an access point (AP), user station (STA), and method for channel sounding in a wireless network are generally described herein. The AP may transmit a null data packet (NDP) announcement to indicate an NDP time period reserved for transmission of an NDP by the AP. The AP may further transmit a trigger frame for sounding (TFS) to indicate a scheduled sounding feedback period for multiple STAs, which may include identifiers of the STAs. The AP may further receive sounding feedback from at least some of the STAs during the sounding feedback period.
