This approach allows, for example, the node to use a first or normal data-to-subcarrier mapping for transmissions that are targeted to receivers that do not need an effective increase of the CP length, while using the modified mapping for those receivers that need a longer effective CP length, e.g., because of receiver type or channel conditions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmission in a wireless communication network","description":"A node in a wireless communication network uses a modified data-to-subcarrier mapping on at least a selective basis, wherein the modified mapping effectively extends the cyclic prefix (CP) of a transm","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9838173","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.
