1. A method for transmitting a Sounding Reference Signal (SRS) in a cooperative communication system, the method comprising:
receiving SRS resource information indicating a transmission resource of an SRS to be transmitted by a user equipment (UE), from a macro base station;
transmitting the SRS and uplink data based on a UE-specific SRS subframe configuration included in the SRS resource information when the SRS resource information includes UE-specific SRS subframe configuration information; and
transmitting the SRS and the uplink data based on a pre-stored cell-specific SRS subframe configuration when the SRS resource information does not include the UE-specific SRS subframe configuration information,
wherein one of one or more remote radio heads (RRHs) for the macro base station is selected as a destination of the SRS to be transmitted by the UE, the SRS resource information includes the UE-specific SRS subframe configuration information of the one of the one or more RRHs for the macro base station selected as the destination of the SRS, and
wherein the UE-specific SRS subframe configuration information allows a last SC-FDMA symbol of a subframe to be used in transmitting the uplink data, when the uplink data is transmitted in the subframe in which the SRS is not transmitted.
