The method according to an embodiment includes receiving at least one physical downlink control channel (PDCCH) or at least one physical downlink shared channel (PDSCH); and generating reception response information for the at least one PDCCH or the at least one PDSCH. When the reception response information and channel status information are configured to be transmitted in a same subframe and a first physical uplink control channel (PUCCH) format is configured for the communication apparatus, if a certain condition is satisfied, the reception response information and the channel status information are transmitted together using a second PUCCH format. The certain condition includes a first condition of a single PDSCH transmission only on a primary cell (PCell) where there is not a corresponding PDCCH being present."},"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","description":"A method and a communication apparatus for transmitting uplink control information in a wireless communication system using time division duplex (TDD).
