Original Abstract Submitted
A method and a device for a sounding procedure comprising transmission or reception of a null data physical layer protocol data unit (PPDU) (NDP) announcement frame, which is related to support of an aggregated-PPDU (A-PPDU) in a wireless LAN system are disclosed. A method for performing a sounding procedure by a first station (STA) in a wireless LAN system according to an embodiment of the present disclosure may comprise the steps of: receiving an NDP announcement frame from a second STA on a first frequency unit related to a first type physical layer protocol date unit (PPDU) format and a second frequency unit related to a second type PPDU format; and transmitting, to the second STA, a feedback frame related to one or more of the first frequency unit and the second frequency unit, wherein the NDP announcement frame is a single type NDP announcement frame, and comprises a specific STA information (Info) field configured to have a specific association identifier (AID) value.
