Abstract: The present invention provides a method for defining, and for transmitting, a new uplink reference signal and devices supporting the method. In one embodiment of the present invention, a method in which a terminal transmits a millimetre wave reference signal (mW-RS) in a millimetre-wave (mmWave)-supporting wireless access system comprises the steps of: receiving a downlink reference signal in a predetermined number of sub-frames, and measuring two or more received power levels; determining whether to transmit an mW-RS, based on the value(s) of the difference(s) between the two or more received power levels; and transmitting the mW-RS if it has been decided to transmit an mW-RS. Here, the mW-RS is transmitted in order to measure whether the state of a wireless channel has transitioned between an LoS (Light of Sight) state and a NLoS (Non-LoS) state.
