Various disclosed techniques may determine a transmit power for a subsequent transmission based on channel characteristics during one or more clear channel assessment (CCA) time durations. The transmit power may be selected to provide a CCA threshold that may increase the likelihood that a device will win contention for the channel during the CCA procedure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"CCA clearance in unlicensed spectrum","description":"Techniques are described for contention-based wireless communications channel access that may improve the likelihood that a contention procedure will pass and allow a device to transmit an uplink or d","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9743363","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.
