Method for controlling interference in an overlaid network environment

A time-domain inter-cell interference control method of a base station in a heterogeneous network environment, comprising:

• setting system information (SI) transmission resources;
• transmitting SI using only the SI transmission resources or preferentially using the SI transmission resources when SI is transmitted using a sub-frame designated as an almost blank sub-frame (ABS);
• and
• transmitting physical downlink shared channel (PDSCH) data to user equipment (UE) only when the SI transmission resources are not being used,
• wherein, when the sub-frame, some of whose resources are punctured, are set to be specific to the cell managed by the base station, information about the sub-frame is transmitted to the UE using SI broadcast by the base station.

A time-domain inter-cell interference control method of user equipment (UE) in a heterogeneous network environment, comprising:

• receiving information about sub-frames, some of whose resources are to be punctured;
• and
• receiving data using a region excluding the resources to be punctured in a corresponding sub-frame based on the information about the sub-frames,
• wherein, when the sub-frames, some of whose resources are punctured, are set to be specific to a cell to which the UE belongs, the information about the sub-frames, is received using system information (SI) broadcast by the base station.
