Abstract: The present invention provides a method for carrying out S-TTI-based communication performed by a terminal supporting a relatively short transmission time interval (S-TTI) compared to a legacy transmission time interval (L-TTI) in a wireless communication system. The method is characterized by: determining a value with respect to a ratio of reference signal energy per resource element (RS EPRE) to physical downlink shared channel energy per resource element (PDSCH EPRE); and carrying out S-TTI-based communication on the basis of the value with respect to the ratio, wherein the value with respect to the ratio is determined in an S-TTI unit.

Abstract: The present invention provides a method for a base station to transmit a downlink signal, in order to reduce interference between uplink transmission and downlink transmission in a wireless communication system. Particularly, the method is characterized by: a step of setting a power decrease region in which downlink transmission power is transmitted by being lower than that of another region; a step of separating and generating a first transmission block corresponding to the power decrease region, and a second transmission block not corresponding to the power decrease region; and a step of mapping downlink data to the first transmission block and the second transmission block, respectively, wherein the first transmission block is transmitted with the power allocated to the power decrease region, and the second transmission block is transmitted with the power allocated to the region other than the power decrease region.
