The present application discloses a method for transmitting a downlink signal by a base station in a wireless communication system. Particularly, the method comprises the steps of: distributing a total transmission power with respect to data for a short range user equipment (UE) and data for a long range UE; and transmitting the data for the short range UE through a plurality of layers, and transmitting the data for the long range UE through at least one of the plurality of layers, using the distributed transmission power, wherein the data for the short range UE and the data for the long range UE are transmitted through the same time resource and the same frequency resource, and a transmission power of the data for the short range UE distributed for each of the plurality of layers has an equal value.
