The DCI comprises at least one code word indicating a rank of a channel matrix between the transmitter portion of the node and the wireless station greater than 4 and a spatial-related configuration for the wireless station. In one exemplary embodiment, the transmitter portion transmits the DCI from one substantially localized geographical transmission point forming a single-cell access point for the plurality of wireless stations. In another exemplary embodiment, the transmitter portion transmits the DCI from multiple geographically substantially isolated transmission points forming a single-cell access point."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Higher order MU-MIMO for LTE-A","description":"An access node of a 3GPP LTE-based wireless communication network comprises a transmitter portion that transmits downlink control information (DCI) to at least one wireless station of a plurality of w","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9807617","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.
