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.

Abstract: Disclosed is a method for transmitting a physical uplink control channel (PUCCH) by a machine type communication (MTC) device. The PUCCH transmission method comprises the steps of: receiving configuration for independent PUCCH resources at each repetition level of PUCCH; determining a PUCCH resource corresponding to a repetition level, on the basis of the configuration; and repeatedly transmitting the PUCCH, on the determined resource.
