According to one aspect of the present invention, a method for transmitting a PPDU frame to a reception apparatus by a transmission apparatus in a WLAN may be provided. The method may include generating a legacy preamble, generating a High Efficiency (HE)-preamble, and transmitting a PPDU frame including a first region and a second region to the reception apparatus, the first region including the legacy preamble and a first field and the second region including the HE-preamble. The first field may have a variable length, and the HE-preamble may include a High Efficiency-Short Training Field (HE-STF) following the first field."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Physical layer protocol data unit format in a high efficiency wireless LAN","description":"The present invention relates to a new Physical layer Protocol Data unit (PPDU) format and a transmission and reception method and apparatus using the new PPDU format in a Wireless Local Area Network ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9673943","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
