Abstract: The present invention relates to a method for transmitting an uplink channel in a wireless communication system. The method for transmitting an uplink channel of a terminal according to one embodiment of the present invention may comprise the steps of: receiving a downlink control message; extracting the starting point of a dynamic physical uplink control channel (PUCCH) resource region from the downlink control message; and transmitting an uplink channel according to the starting point of the extracted dynamic PUCCH resource region. An embodiment of the invention exhibits effects in reducing the signaling overhead, and preventing the terminal from unnecessarily consuming power, when transmitting the uplink channel in a CoMP system.

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.
