Disclosed are a method and an apparatus for transmitting and receiving data. A method for transmitting an uplink comprises the steps of: a terminal determining the size of an ACK/NACK payload according to a transmission mode of a first serving cell and a transmission mode of a second serving cell; the terminal establishing a transmission power for transmitting the ACK/NACK payload based on the size of the ACK/NACK payload; and the terminal transmitting the ACK/NACK payload through a physical uplink control channel (PUCCH) based on the transmission power.
