Abstract: The present disclosure provides a wireless communication method. The wireless communication method includes a first apparatus communicating with at least one second apparatus in a wireless local area network (WLAN) system. The wireless communication method generates an aggregated physical layer protocol data unit (PPDU) including a first null data packet (NDP) based on a first protocol standard and a second NDP based on a second protocol standard and transmits the aggregated PPDU to the at least one second apparatus, wherein the first NDP and the second NDP have a same duration in different frequency bands.
