Abstract: A Virtual Antenna Mapping (VAM) method of a base station and a transmission apparatus equipped with M physical antennas and Q Transceiver Units (TXRUs) are provided. The method includes transmitting Reference Signals (RSs) arranged differently according to respective VAM patterns to a terminal in a transmission mode supporting N logical antennas; receiving a feedback including information regarding a VAM pattern selected as a result of channel measurement with respect to the RSs transmitted according to the VAM pattern from the terminal; and transmitting a signal to the terminal through the M physical antennas by applying the selected VAM pattern, wherein the selected VAM pattern maps N data streams corresponding to the N logical antennas to the M physical antennas through the Q TXRUs.
