Claim Text:
1. A time-domain inter-cell interference control method of a base station in a heterogeneous network environment, comprising: transmitting information about sub-frames, some of whose resources are to be punctured, to user equipment (UE); puncturing the some resources of the corresponding sub-frame based on the information about the sub-frames and transmitting the sub-frame, some of whose resources are punctured, to the UE; and transmitting physical downlink shared channel (PDSCH) data to the UE only when the some resources of the corresponding sub-frame are not punctured, wherein, when the sub-frames, some of whose resources are punctured, are set to be specific to a cell managed by the base station, the information about the sub-frames is transmitted to the UE using system information (SI) broadcast by the base station.
