摘要： Disclosed are a method for estimating a channel state in a CoMP operation of a terminal and a method for generating channel state information of a base station. A terminal can measure strength or an interference level of a signal of each cell using a reference signal received from each cell for performing the CoMP operation.

In addition, the terminal can transmit to the serving base station the strength or the interference level of the signal of each cell for performing the measured CoMP operation and the sum of the interference levels of the cells which do not perform the CoMP operation. At this time, the data of the adjacent cells for performing the CoMP operation are mapped on regions except for the region on which the reference signal of the serving cell is mapped and the reference signal of the serving cell and the signals of the cells which do not perform the CoMP operation can be separated by particular tones in the region on which the reference signal of the serving cell is mapped.
