The present invention relates to a method and an apparatus for transmitting a HARQ ACK/NACK signal and a scheduling request (SR) over an identical uplink subframe by a terminal in a time division duplex (TDD) system in a carrier aggregation environment. An example of a method for transmitting an HARQ ACK/NACK signal and an SR according to one embodiment of the present invention comprises the steps of: receiving an allocation of a plurality of SR PUCCH resources; and transmitting a HARQ ACK/NACK signal using the plurality of SR PUCCH resources. According to the present invention, in the event a HARQ ACK/NACK signal and an SR are transmitted over an identical uplink subframe in a time division duplex (TDD) system in a carrier aggregation environment, the HARQ ACK/NACK signal may be transmitted such that the HARQ ACK/NACK signal and the SR may be retransmitted only for the PDSCH which has not successfully received the signal and the SR, instead of retransmitting the signal and the SR for all PDSCHs. |
