A base station apparatus communicates with a first communication terminal in a first frequency band and also communicates with a second communication terminal in a second frequency band of a narrower bandwidth than the first frequency band, and includes: an allocation control section that allocates an extended downlink control channel which is frequency-division-multiplexed with a downlink shared data channel, in a predetermined frequency region in the second frequency band; and a mapping section that maps a common control signal that is common between the second communication terminals at least, in a common search space of the extended downlink control channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Base station apparatus, radio communication terminal, radio communication system and radio communication method","description":"The present invention is designed to provide a base station apparatus, a radio communication terminal, a radio communication system and a radio communication method which can reduce the cost required ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9628236","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.
