Abstract:
The present invention presents a method by which a base station notifies a terminal of information on a tone into which interference caused by surrounding cells greatly flows, and by which a terminal uses the information so as to efficiently remove the interference caused by the surrounding cells and to demodulate data channels, such that the method improves reception performance. Particularly, when the surrounding cells transmit cell-specific reference signals, the base station transmits, to the terminal, location information of the cell-specific reference signals transmitted by the surrounding cells, and the terminal demodulates the received data except for a data channel tone in which cell-specific reference signals of the surrounding cells greatly cause interference. The present invention can improve data reception performance by efficiently removing the interference caused by the surrounding cells.
