摘要：
The present invention provides a method and apparatus in which user equipment sends channel state information. The method includes receiving mapping information informing an uplink (UL) channel mapped to a reference signal; determining a valid downlink (DL) subframe based on the mapping information; measuring the reference signal in the valid DL subframe; and transmittingg Channel State Information (CSI), generated based on the measurement, in a configured UL subframe, wherein the UL channel is placed in the configured UL subframe, and the valid DL subframe is a DL subframe including the reference signal mapped to the UL channel.
