In an embodiment, an indication of signal powers of the transmit antennas is signaled by the network to the user equipment (UE) when the UE is configured for logical antenna ports using non-collocated and/or power imbalanced transmit antennas. The UE can use the indication of signal powers in determining the Precoding Matrix Indicator (PMI) and the Channel Quality Indicator (CQI), resulting in higher accuracy link adaptation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Efficient link adaptation for non-collocated antennas","description":"Systems and methods for efficient link adaptation in multi-access wireless communication networks, including link adaptation in scenarios with non-collocated and/or power imbalanced base station trans","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9769679","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.
