One embodiment of the present invention relates to a method for transmitting signals over an unlicensed band phase of a base station in a wireless communication system, which comprises the steps of: transmitting a physical down-link control channel (PDCCH) from a licensed band; and transmitting a physical down-link shared channel (PDSCH) over a time interval of the unlicensed band corresponding to the sub-frame transmitted by the PDCCH, wherein a reservation signal can be transmitted to a pre-set point from the point the unlicensed band is available to the base station, if the base station performs wave transmission sensing for the unlicensed band for transmission of the PDSCH, and the pre-set point is earlier than the point at which the unlicensed becomes available from the transmission sensing results. |
