Abstract: Disclosed is a method and device for transmitting a sounding reference signal (SRS) in a cooperative communication system. The method comprises the steps of: receiving, from a macro base station, SRS resource information indicating transmission resources of an SRS to be transmitted by a user equipment (UE); transmitting the SRS and uplink data on the basis of a UE-specific SRS subframe configuration included in the SRS resource information when the SRS resource information includes information on the UE-specific SRS subframe configuration; and transmitting the SRS and the uplink data on the basis of a pre-stored cell-specific SRS subframe configuration when the SRS resource information does not include the information on the UE-specific SRS subframe configuration. When a destination of the SRS to be transmitted by the UE is selected as a base station related to the macro base station, the SRS resource information includes information on the UE-specific SRS subframe configuration of the base station selected as the destination of the SRS.

Abstract: Methods and apparatuses are provided for reporting channel status by a user equipment (UE) in a communication system. Information on at least one channel status information reference signal is received from an evolved node B. A first channel status based on a first period and a first set of the at least one channel status information reference signal, is reported to the evolved node B. A second channel status based on a second period and a second set of the at least one channel status information reference signal, is reported to the evolved node B. The first channel status includes at least one of a precoding matrix indicator (PMI), a channel quality indicator (CQI), and a ranking indication (RI), and the second channel status includes at least one of a CQI, a PMI and a RI. The RI of the second channel status is same as the RI of the first channel status.
