Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting higher data transmission rates than 4th generation (4G) communication systems such as long term evolution (LTE). A method performed by a first base station in a wireless communication system includes: identifying a first signal-to-interference-noise ratio (SINR), based on channel state information received from a terminal; identifying a modulation and coding scheme (MCS), based on the first SINR and information on a link direction of a second base station; and transmitting information indicating the MCS to the terminal.

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.
