APPARATUS AND METHOD FOR NETWORK-ASSISTED INTERFERENCE CANCELLATION AT DOWNLINK USING ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING

摘要

The present invention suggests a method for informing a terminal of information on a tone by which an interference that influences peripheral cells, by a base station, and efficiently removing the interference influenced by the peripheral cells to demodulate a data channel by the terminal, thereby increasing signal reception performance. In particular, when a peripheral cell transmits a cell specific reference signal, the base station transmits location information of a cell specific reference signal transmitted by the peripheral cell, and the terminal demodulates the received data except for a data channel tone that is severely interfered by the cell specific reference signal of the peripheral cell. According to the present invention, data reception performance can be increased by efficiently removing an interference influenced by a peripheral cell.
