The second scrambling sequence is an N-bit left cyclic shift of the first scrambling sequence. Another wireless device generates first scrambled data using a first scrambling sequence and transmits an MU-RTS frame including the first scrambled data. The wireless device receives a CTS frame transmitted in response to the MU-RTS frame, and descrambles second scrambled data in the CTS frame using a second scrambling sequence. The second scrambling sequence is an N-bit left cyclic shift of the first scrambling sequence. In either device, N may be 7, and lengths of the first and second scrambling sequences may be 127 bits."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protection methods for wireless transmissions","description":"A wireless device receives a Multi-User Request-To-Send (MU-RTS) frame, descrambles first scrambled data in the MU-RTS frame using a first scrambling sequence, generates second scrambled data using a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667394","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.
