Specifically, an AP generates FDR indication information that FDR can be performed. The AP transmits a DL PPDU including the FDR indication information to a first STA. The AP receives a UL PPDU from the first STA. The DL PPDU includes a legacy signal field, a first signal field, a second signal field, a third signal field, and a DL data field. The second signal field includes information on an RU placement in the entire frequency band and allocation information for a first RU to which the DL data field is allocated. The third signal field includes allocation information for a second RU to which the UL PPDU is allocated on the basis of the information on the RU placement. The allocation information for the second RU includes a bitmap of whether the UL PPDU is allocated in units of 26 RUs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting PPDU on basis of FDR in wireless LAN system","description":"A method and an apparatus for transmitting and receiving PPDU on the basis of FDR in a wireless LAN system are presented.
