A method by a UE includes receiving a trigger for an aperiodic CSI report as part of an uplink (UL) grant from a radio node in a static downlink (DL) subframe, where the trigger indicates a CSI subframe set, out of at least two alternative CSI subframe sets. An aperiodic CSI measurement is performed for a CSI reference resource in the indicated CSI subframe set, and the result of the CSI measurement is reported to the radio node. One of the at least two alternative CSI subframe sets relates to the one or more static subframes, and another one of the at least two alternative CSI subframe sets relates to the one or more flexible subframes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and radio node for handling CSI reporting","description":"Separate aperiodic channel state information (CSI) reports are handled for static subframe(s), in which the direction of signal transmission is fixed, and flexible subframe(s), in which the direction ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9680581","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.
