Abstract
A method is provided for transmitting control information from a terminal in a wireless communication system. Physical downlink shared channels (PDSCHs) are received on a primary component carrier and PDSCHs are received on a secondary component carrier. The primary component carrier and the secondary component carrier are configured for the terminal. A first acknowledgement (ACK)/negative acknowledgement (NACK) feedback is transmitted for the received PDSCHs on a first physical uplink control channel (PUCCH) resource corresponding to a first antenna port and a second ACK/NACK feedback is transmitted for the received PDSCHs on a second PUCCH resource corresponding to a second antenna port. The first antenna port and the second antenna port are configured for the terminal. The first ACK/NACK feedback and the second ACK/NACK feedback are identical.
