Claim:
1. A method for receiving a downlink signal by a user equipment (UE) in a Time Division Duplex (TDD) wireless communication system supporting Coordinated Multi-point (CoMP) transmission and reception in which at least two cells having different uplink-downlink (UL-DL) configurations or different special subframe configurations participate, the method comprising: acquiring, by the UE, information of a time-resource region in which a downlink signal for the CoMP transmission and reception is received from at least one cell of the at least two cells; and receiving, by the UE from the at least one cell, the downlink signal for the CoMP transmission and reception using the acquired information of the time-resource region, wherein the acquired information of the time-resource region includes a length of a time region in a specific subframe in which the downlink signal for the CoMP transmission and reception is received from the at least two cells having different UL-DL configurations or different special subframe configurations participate, and wherein if the downlink signal for the CoMP transmission and reception is transmitted in special subframes of at least two cells having the same UL-DL configuration and different special subframe configurations, the acquired information of the time-resource region includes a minimum value from among lengths of a downlink pilot time slot (DwPTS) of the special subframes.
