A base station device includes a first control unit that updates a CFI value at a first interval, a second control unit that updates a PHICH duration value at a second interval, the second interval being greater than the first interval, and a scheduling unit that performs scheduling of, only in a subframe in which the PHICH duration value matches the CFI value, data to be sent to a communication terminal device that is outside an arrival coverage of a signal including the CFI value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication terminal device, base station device, and communication system","description":"A communication terminal device includes a determining unit that determines a region size of a control channel in accordance with a PHICH duration value transmitted from a base station device, and an ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9730209","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.
