Abstract: The present invention relates to a method for transmitting and receiving signals in a wireless communication system. Specifically, in a multi-cell cooperative communication system, a base station can form cooperative detection user set information by detecting a terminal within a cell and form cooperative processing user set by receiving the cooperative detection user set information of a neighboring base station. At this time, the base station acquires information about a base station adjacent to the neighboring base station and designs an efficient filter in transmitting and receiving signals of terminals between the base stations, thereby being capable of removing inter-cell interference signals.
