A first method of signaling to negotiate the channel bandwidth conveys the needed information in the SIG field of the PPDUs of duplicate RTS/CTS frames, and uses the SIG field of PPDUs of duplicated data, control and management frames to perform transmit opportunity protection. A second method of signaling to negotiate the channel bandwidth conveys the needed information in the scrambling sequence field of PPDUs of duplicate RTS, and uses the scrambling sequence field of PPDUs of duplicated data, control and management frames to perform transmit opportunity protection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel bandwidth indication and TXOP protection","description":"Methods and systems are disclosed for the operation of wireless communication networks, in which communication channels can have possibly overlapping bandwidths of different sizes, including sensor ne","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9826434","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.
