The user equipment supports one or more MIMO modes associated with four branch MIMO and one or more of a single stream restriction, a dual stream restriction and no restriction. The controlling node controls a base station. The user equipment signals at least one of said supported MIMO modes to the controlling node that determines one of said at least one MIMO modes to be used by the user equipment. The controlling node sends, to the user equipment, a mode instruction instructing the user equipment to use the determined MIMO mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Handling of stream restriction in a cellular communications system supporting four branch MIMO","description":"Methods, user equipment and controlling node for handling of stream restriction of the user equipment in a cellular communications system supporting four branch Multiple Input Multiple Output (MIMO) a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9591477","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.
