Method and Device Transmitting Interference Information for Network Assisted Interference Cancellation and Suppression in Wireless Communication Systems

摘要

The present invention relates to a method and apparatus for transmitting interference-related control information in order to improve reception performance of a terminal receiving a downlink in a cellular mobile communication system based on an LTE-A system, and in one embodiment of the present invention The communication method of the terminal according to the present invention comprises the steps of: receiving a higher layer control message including probability information of a modulation method for an interference signal from a base station; and performing error correction decoding using a probability value of a modulation scheme for the interference signal included in the higher layer control message. According to an embodiment of the present invention, it is possible to improve the reception performance of the terminal through interference cancellation and suppression.
