Interference cancellation receiving method and interference cancellation receiving terminal

摘要

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.
