Method for controlling uplink transmission power in wireless communication system, and apparatus therefor

The present invention discloses a method for controlling uplink transmission power in a wireless communication system, and an apparatus therefor. Specifically, the method comprises the steps of: reporting to a base station, terminal capability information regarding uplink transmission power; receiving from the base station, indication information on the transmission power of a first uplink channel and indication information on the transmission power of a second uplink channel; transmitting the first uplink channel according to the transmission power of the received first uplink channel; and transmitting the second uplink channel according to the transmission power of the received second uplink channel, wherein a transition threshold due to the difference between the transmission power of the first uplink channel and the transmission power of the second uplink channel can be configured to be included in either one of the region to which the first uplink channel is transmitted or the region to which the second uplink channel is transmitted.
