Abstract: A resource allocation method according to the present invention may comprise the steps of: allocating a signal of an external resource to a predetermined resource according to a preconfigured resource allocation frame structure by a first base station governing a first cell; allocating a signal of an internal resource to the resource according to the resource allocation frame structure by a second base station governing a second cell adjacent to the first cell; and frequency-hopping the signal of the internal resource by the second base station when the signal of the internal resource overlaps the signal of the external resource. Accordingly, proposed is a resource allocation method capable of stably receiving a signal even when a terminal moving in a dense small cell structure is located at a cell edge, that is, an inter-cell boundary area.

Abstract: Provided are a method and a device for arranging a subframe structure of a short TTI according to the change in a control region in a wireless communication system. Specifically, a plurality of first downlink channels received during an sTTI and a second downlink channel received during a TTI are received. The number of symbols used for each of the plurality of first downlink channels is determined by a format indicator channel included in the first symbol of a subframe. Further, the plurality of first downlink channels are demodulated by using scheduling information included in each of the plurality of first downlink channels, and the second downlink channel is demodulated by using scheduling information included in a control region indicated by the format indicator channel.
