PROBLEM TO BE SOLVED: To provide a method suitable for transmitting reference signals for measuring a channel in a downlink MIMO (Multi Input Multi Output) system.SOLUTION: The method comprises the steps of: configuring, by a base station at which Nt (Nt≥1) transmit antennas are configured, Nt reference signals for channel measurement; and transmitting, by the base station, the Nt reference signals to user equipment in subframes with a specific cycle. The specific cycle is configured to include two or more subframes. |
