Abstract: A method of allocating resources according to the present invention comprises the steps of: allocating a signal having a first beam width from a first base station controlling a first cell to a predetermined resource; and allocating a signal, having a second beam width different from the first beam width, from a second base station controlling a second cell adjacent to the first cell to the resource. The signal having the first beam width may be a signal having a first priority, and the signal having the second beam width may be a signal having a second priority that is different from the first priority. Accordingly, a method for allocating resources is proposed which can stably receive signals even when a terminal that moves in a dense small cell structure is at a cell edge or a border region between cells.
