Abstract
A method, station (STA), and access point (AP) for transmitting in a WLAN. A station includes a controller and a transceiver, the transceiver configured to receive, from an AP, a channel sounding sequence including a null data packet announcement frame (NDPA) including information indicating STAs to transmit a feedback report, a null data packet (NDP) containing pilots to compute the feedback report and a trigger frame (TF) to trigger transmission of the feedback report. An AP includes a controller and a transceiver, the controller configured to generate a NDPA including information indicating STAs to transmit a feedback report, a NDP containing pilots to compute the feedback report, and a TF to trigger transmission of the feedback report from at least one of the STAs, and the transceiver is operably connected to the controller and configured to transmit a channel sounding sequence that includes the NDPA, the NDP, and the TF.
