The operation method includes generating a legacy preamble, generating a high efficiency (HE) preamble including at least one HE-signal (HE-SIG) field, a HE-short training field (HE-STF), and at least one HE-long training field (HE-LTF), and generating a HE physical layer convergence procedure protocol data unit (HE-PPDU) including the legacy preamble and the HE preamble. Therefore, performance of WLAN can be enhanced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless local area network communications with varying subcarrier spacings","description":"An operation method of station in wireless local area network is provided.
