Abstract:
The present invention relates to a method and a device for receiving a downlink signal by a terminal in a wireless communication system using a time division duplex (TDD) scheme. Specifically, the present invention comprises the steps of: receiving a usage change message indicating a change from a first uplink-downlink configuration to a second uplink-downlink configuration; with regard to a specific subframe, when a wireless frame type according to the first uplink-downlink configuration is different from a wireless frame type according to the second uplink-downlink configuration, determining a subframe type on the basis of a special subframe configuration associated with the first uplink-downlink configuration; and receiving a downlink signal on the basis of the determined subframe type.
