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.

Abstract: A method for selecting a serving cell by a user equipment (UE) to which the inter-site carrier aggregation (CA) technology is according to the intensity of a reception signal of each carrier wave is provided. However, in order to improve resource usage and a throughput of the entire cells, a method is performed in which a PCell and an SCell are selected considering the intensity of a reception signal and a load between cells, the SCell is activated, and loads of the PCell and the SCell are adjusted. The method can balance an inter-cell traffic load, and eventually, increase usage of the entirety of a network and improve a throughput.
