摘要：
The present invention relates to a method for transmitting reference signals for measuring a channel in a downlink MIMO (Multi Input Multi Output) system. The method comprises the steps of: configuring, by a base station at which Nt transmit antennas are configured, Nt reference signals for channel measurement, where Nt≧1; and transmitting, by the base station, the Nt reference signals to a use equipment in subframes at a specific cycle. The specific cycle is configured to include more than one subframe.
