Methods, apparatuses, computer readable media for trigger frames for sounding in a wireless network. An apparatus of a wireless device is disclosed, which includes processing circuitry configured to: encode a null data packet (NDP) announcement (NDP-A) including an indication of stations, configure the wireless device to transmit the NDP-A, and encode a high-efficiency (HE) NDP. The processing circuitry may be further configured to configure the wireless device to transmit the HE-NDP and encode a trigger frame (TF) including feedback parameters for the stations and a resource allocation for each of the stations to transmit a feedback report to the wireless device. The feedback report is based on the feedback parameters and the HE-NDP. The processing circuitry may be further configured to configure the wireless device to transmit the trigger frame, and decode the feedback reports from the stations in accordance with the corresponding resource allocation and the feedback parameters.
