The present invention relates to methods for determining whether to perform millimeter wave (mmWave) scanning in a mmWave system, and a device supporting same. The method for a terminal performing mmWave scanning in a wireless access system supporting mmWave technology, according to one embodiment of the present invention, comprises the steps of: attempting to detect a mmWave pilot signal by monitoring a mmWave pilot detection window in a mmWave band; and transmitting, to an uplink of a legacy band, a feedback signal for indicating whether the mmWave pilot signal is detected, wherein the method may further comprise the step of, if the mmWave pilot signal is detected, performing mmWave ray scanning with a base station, or the step of, if the mmWave pilot signal is not detected, determining whether to perform mmWave beam scanning or whether to perform legacy communication. |
