Abstract:
One embodiment of the present specification provides an interference cancellation receiving method. According to the method, interference estimation support information can be received from a serving cell. The information includes information for a time domain and information for a frequency domain, wherein the information for a time domain can indicate a section of a subframe or a radio frame in which the coherence of an interference signal is maintained, and the information for a frequency domain can indicate a section in which the coherence of the interference signal is maintained. According to the method, an interference signal introduced from a neighboring cell is estimated by using the information for a time domain and the information for a frequency domain of the interference estimation support information, and a signal from the serving cell can be detected by cancelling the estimated interference.
