Among the several mitigation techniques disclosed herein, a wireless device may reduce possible out-of-band interference arising from its D2D transmissions by adjusting transmit power and/or time/frequency resource allocations when it is determined that there is an interference risk. Such mitigations provide improved performance for the D2D transmissions and for the communications in the critical frequency band."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for device-to-device transmissions","description":"This disclosure presents a method and apparatus for mitigating interference arising from Device-to-Device, D2D, communications, in cases where the frequency band used for D2D transmissions is adjacent","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9681331","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.
