For HARQ-ACK timing, in cases where a reference UL-DL configuration applied to the second cell is any one of UL-DL configurations #1 to #6, the DAI field is used in a process of transmitting the HARQ-ACK information. For HARQ-ACK timing, in cases where a reference UL-DL configuration applied to the second cell is #0, the DAI field is not used in a process of transmitting the HARQ-ACK information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting control information in wireless communication system","description":"The present invention relates to a wireless communication system, particularly, a method in which a terminal transmits control information in a CA-based wireless communication system and an apparatus ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9648608","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.
