Method and apparatus for controlling uplink transmission power in wireless communication system supporting machine-type communication

An MTC UE for controlling uplink transmit power in a wireless communication system supporting MTC (machine type communication), comprising:

• a transceiver;
• and
• a processor configured to control the transceiver, the processor configured to calculate a first maximum power reduction value to be applied to a first uplink channel, the processor configured to transmit the first uplink channel using maximum transmit power to which the first maximum power reduction value is applied in a plurality of subframes,
• wherein the first uplink channel is transmitted via frequency resources different from each other within a plurality of the subframes, wherein the maximum transmit power included a different value according to a frequency resource in which a specific channel is transmitted, and wherein a prescribed value is applied to the first maximum power reduction value while the first uplink channel is transmitted.
