A slave station apparatus converts a received optical signal into an electrical signal, separates, from the electrical signal, the frequency-domain user data and the data originating from the modulated control data, modulates the frequency-domain user data, adds resource element information to the modulated user data, and transmits time-domain composite data including a component originating from the modulated user data and a component originating from the modulated control data by radio waves."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio base station, master station apparatus, slave station apparatus, and control method","description":"A master station apparatus modulates downlink digital control data that includes at least a synchronization signal and a control signal, adds resource element information to the modulated control data","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9602175","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.
