    Abstract: A method of generating reference signals by a base station in a wireless communication system is disclosed. The method including a sequence of a first reference signal using a cell identifier of the base station, transmitting, to a first user equipment (UE), a message including mode information indicating a first mode for a coordinated multi-point (CoMP) operation and a predetermined identifier being different from the cell identifier of the base station and generating a sequence of a second reference signal for the first UE using the predetermined identifier instead of the cell identifier of the base station.
