Claim:
1. A method for receiving a downlink signal by a user equipment (UE) supporting a plurality of carrier types in a wireless communication system, the method comprising: receiving, by the UE, a first downlink signal through a downlink pilot time slot (DwPTS) in a special subframe including the DwPTS, a guard period (GP), and an uplink pilot time slot (UpPTS), wherein a length of the DwPTS is less than or equal to half the special subframe; and demodulating, by the UE, the first downlink signal, wherein the first downlink signal is demodulated using a first cell-common reference signal when the first downlink signal is received on a first type carrier, wherein the first downlink signal is demodulated using a UE-specific reference signal when the first downlink signal is received on a second type carrier, and wherein the first downlink signal is scheduled by a first physical downlink control channel (PDCCH) signal transmitted through a downlink subframe prior to the special subframe on the second type carrier, when the first downlink signal is received on the second type carrier.
