Abstract: The present invention relates to a method for controlling transmission power in a wireless access system that supports an operation in an unlicensed band, and to an apparatus for same. More particularly, the method for controlling the transmission power of a terminal in a wireless access system that supports a TV white space (TV WS) band comprises the steps of: allocating, to a terminal, an available frequency band which is not used by a licensed device from among the TV WS band; calculating, if a receiving band of another device exists in a band adjacent to the available frequency band, the maximum transmission power value of the terminal based on a level of interference which will not affect the reception of another device; and transmitting, to the terminal, transmission power control information for correcting the transmission power of the terminal on the basis of the maximum transmission power value.
