PROBLEM TO BE SOLVED: To provide a method for transmitting ACK/NACK in a TDD-based wireless communication system.SOLUTION: A method for transmitting ACK/NACK in a TDD-based wireless communication system includes the steps of: receiving M (M>2) downlink subframes coupled to an uplink subframe n in each of two serving cells; determining four candidate resources on the basis of the M downlink subframes received; and transmitting ACK/NACK response to the M downlink subframes received using one resource selected from among the four candidate resources in the uplink subframe n. The two serving cells include first and second serving cells. Among the four candidate resources, first and second resources are associated with a PDSCH received by the first serving cell or a SPS releasing PDCCH releasing a semi-persistent scheduling, and third and fourth resources are associated with a PDSCH received by the second serving cell.SELECTED DRAWING: Figure 10 |
