Method for transmitting and receiving downlink signal in wireless communication system and device for same

A user equipment for receiving a downlink signal in a wireless communication system of a time division duplex (TDD) scheme, the user equipment comprising:

• a transceiver;
• and
• a processor,
• wherein the processor is configured to:
• control the transceiver to receive a usage change message for informing of a change from a first uplink-downlink (UL-DL) configuration to a second UL-DL configuration,
• wherein the usage change message informs of that a special subframe of the first UL-DL configuration is to be changed to a downlink subframe of the second UL-DL configuration,
• determine whether the special subframe is changed to the downlink subframe based on a special subframe configuration and a cyclic prefix of the special subframe related to the first UL-DL configuration, and
• control the transceiver to receive the downlink signal based on whether the special subframe is changed to the downlink subframe,
• wherein the special subframe configuration is a special subframe configuration #7 and the cyclic prefix is an extended cyclic prefix, and
• wherein, based on a downlink control information (DCI) format 1A for receiving the downlink signal, the special subframe is determined not to be changed.
