The reference signal may be a channel usage beacon signal (CUBS) transmitted by the serving base station prior to transmission or may be a specific channel state information (CSI) reference signal transmitted in the first subframe of a transmission frame. The UE generates a fast CSI feedback report based on the measured reference signal and transmits it to the serving base station. The fast CSI feedback report is received quickly enough by the serving base station such that the base station may apply the CSI feedback to additional transmissions in subsequent subframes within the same transmission frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel and interference measurement in LTE/LTE-A networks including unlicensed spectrum","description":"Channel and interference measurement in long term evolution (LTE)/LTE-Advanced (LTE-A) networks including unlicensed spectrum is discussed in which a user equipment (UE) detects a reference signal fro","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9681325","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.
