The method includes transmitting, at a base station, information on a primary cell operating in a frequency division duplexing (FDD) mode and a secondary cell operating in a time division duplexing (TDD) mode, transmitting, at the base station, downlink scheduling information for downlink data, transmitting, at the base station, the downlink data in a first subframe according to the downlink scheduling information, and receiving, at the base station, control information corresponding to the downlink data on the primary cell, from a terminal. The control information is transmitted using a physical uplink control channel (PUCCH) format determined based on a type of the first subframe of the secondary cell."},"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 channel in intra-cell carrier aggregation system","description":"A method for receiving control channel and an apparatus in a wireless communication system are provided.
