Abstract
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 measure the sum of the interference levels of the cells which do not perform the CoMP operation using a region from which a reference signal of a serving cell of each cell is transmitted. In addition, the terminal can transmit to the serving base station the strength of 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.
