The determination whether a given pair of communications devices should communicate using direct peer to peer communications, rather than via the infrastructure element(s), is determined by a control device. The control device instructs various wireless terminals to make various signal measurements and/or transmit signals to be measured. Based on the signal measurements the control device estimates interference caused by the direct peer to peer link to the existing communications devices, the direct peer to peer link channel quality and/or interference caused to such a direct peer to peer link by existing communications devices which are communicating using peer to peer signaling and makes a mode decision based on such information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for determining and/or using a communications mode","description":"Methods and apparatus for determining whether two or more communications devices, e.g., wireless terminals, in a communications system should communicate using direct peer to peer communications or vi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8521886","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.
