    Abstract: A method, performed by a transceiver, is described. The transceiver receives a null data packet announcement (NDPA) frame to initiate channel sounding and a null data packet (NDP), the NDP following the NDPA frame. A first report field including beamforming information and a second report field including signal to noise ratio (SNR) information is configured. First feedback data including the first report field and a second report field is split into a plurality of segments. The plurality of segments is transmitted in a single aggregated medium access control protocol data unit (A-MPDU) including MPDUs. A retransmission request including a segment retransmission bitmap field indicating at least one segment of the plurality of segments for retransmission is received. In response to the retransmission request, second feedback data including the at least one segment indicated by the segment retransmission bitmap field is transmitted.

    Abstract: A method of transmitting a frame in a Wireless Local Area Network (WLAN) system is provided. The method includes receiving, by a first station, information about an association identifier (AID) from an access point, the AID identifying the first station in the WLAN system; transmitting, by the first station, a Direct Link Setup (DLS) request frame to a second station to request a setup for a direct link with the second station, the DLS request frame including the AID of the first station; receiving, by the first station, a DLS response frame from the second station in response to the DLS request frame, the DLS response frame including an AID of the second station; and transmitting, by the first station, a Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU) to the second station or the access point.
