The method and associated devices allow a control of TXOP bandwidth or transmission mask where devices capable of both dynamic and static bandwidth operation may be present within the network. The preceding frame may include a non-HT frame of a non-HT duplicate frame exchange, such as a non-HT duplicate RTS/CTS exchange or a BAR/BA exchange, where the bandwidth or the transmission mask would be controlled by being limited to be less than or equal to a bandwidth of the non-HT frame. The preceding frame may include a preceding PPDU, where the bandwidth or the transmission mask would be limited to be less than or equal to a bandwidth of the preceding PPDU."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmission rules within a TXOP for wider bandwidth operation","description":"A method of communicating in a wireless network comprises controlling a bandwidth or a transmission mask of a PPDU transmitted by a transmitting STA to a receiving STA within a TXOP based on bandwidth","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9820304","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.
