Abstract: Disclosed is a method for controlling interference in a heterogeneous network environment. The method for controlling the inter-cell interference of a base station according to one aspect of the present invention comprises the following steps: transmitting, to a terminal, information relating to subframes in which a portion of a resource is to be punctured; transmitting, to the terminal, a relevant subframe in which a portion of a resource is punctured on the basis of the information relating to said subframes. A method for controlling the inter-cell interference of a base station according to another aspect of the present invention comprises the following steps: setting a resource for transmitting system information; and transmitting system information using only said resource for transmitting system information, or preferentially using said resource for transmitting system information when transmitting system information using a subframe designated as an almost blank subframe (ABS). Accordingly, inter-cell interference problems may be alleviated even in the event pieces of important system information, such as CRS, should be transmitted using an ABS.

KSP Keywords: Network Environment, System Information, almost blank subframes(ABSs), base station, heterogeneous network, inter-cell, inter-cell interference
