The present invention relates to a method for receiving a device-to-device signal of a terminal in a wireless communication system supporting frequency division duplex (FDD) band and time division duplex (TDD) band-based carrier aggregation. Particularly, the present invention comprises a step for receiving a D2D signal on an uplink cell of the FDD band according to whether a wide area network (WAN) signal of the TDD band is transmitted and received on a specific sub-frame in which the WAN signal is received on a downlink cell of the FDD band, wherein the D2D signal is received when the TDD band transmits the WAN signal and a reception circuit (RX chain) for the TDD band is reconfigured for the uplink cell of the FDD band.
