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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for channel sounding based on aggregated physical protocol data unit","description":"The present disclosure provides a wireless communication method.
