    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.

    Abstract: The present invention relates to a method by which a terminal measures interference in a wireless communication system in which a macro cell and a small-scale cell coexist. The interference measurement method can include a step in which a terminal receives setting information for interference measurement (IM). Here, the setting information for the IM includes at least two settings, each setting is defined in a resource element (RE) unit, the first of the two settings is for measuring interference from other neighboring cells besides the macro and small-scale cells, and the second is for measuring interference from the macro cell. The interference measurement method may further include: measuring interference by using setting information for the IM; and feeding back channel quality obtained by using the measured interference value.
