Abstract:
The present invention relates to a wireless communication system, and more specifically, disclosed are a method and an apparatus using a null data packet frame in a wireless LAN system. A method for a first station (STA) receiving a null data packet (NDP) type frame in the wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving from a second STA the NDP type frame including a specific frame transmission point offset field; and determining whether to perform an action triggered by the NDP type frame by comparing a value of the specific frame transmission point offset field, and the difference in values of the transmission point of the specific frame and the transmission point of the NDP type frame.
