A METHOD FOR TRANSMITTING DOWNLINK REFERENCE SIGNAL IN MULTI-CARRIER SUPPORTING WIRELESS COMMUNICATION SYSTEM AND AN APPARATUS FOR THE SAME

摘要

PURPOSE: A method and an apparatus for in transmitting a downlink reference signal in a wireless communication are provided to efficiently transmit downlink according to the kind of subframes. CONSTITUTION: A receiving module(3611) receives an link signal from a terminal. A transmitting module(3612) transmits a downlink signal to the terminal. A processor(3613) controls the receiving module and the transmitting module. The processor maps CSI-RS about antenna ports on a data area of a downlink subframe. The processor transmits the downlink subframe which the CSI-RS is mapped about antenna ports through the transmitting module.
