Method for transmitting/receiving signal and device therefor

A user equipment (UE) configured to transmit uplink control information in a TDD (Time Division Duplex) wireless communication system configured with a plurality of serving cells including a first serving cell and a second serving cell, the UE comprising:

• a receiver;
• a transmitter;
• and
• a processor operatively connected to the receiver and the transmitter, the processor configured to
• receive, from a base station (BS), a signal in a downlink subframe via the second serving cell;
• and
• in response to the signal, transmit a HARQ-ACK (Hybrid Automatic Repeat reQuest-Acknowledgement) response to the BS in an uplink subframe via the first serving cell or the second serving cell in accordance with a reference uplink-downlink (UL-DL) configuration that is based on a relationship between an UL-DL configuration of the first serving cell and an UL-DL configuration of the second serving cell as described in the following Table 1,
