Abstract: Disclosed are a terminal and a CSI feedback method of a terminal, comprising the steps of: classifying cells into one or more cell groups on the basis of cell IDs of the cells set in a terminal; selecting a representative cell representing other cells belonging to each cell group; and transmitting a CSI feedback on the cells belonging to each cell group to at least one of a macro cell and a small cell connected to the terminal by using the representative cell selected in each cell group.
