Abstract

Disclosed are methods for providing interference information in mobile communication systems. The method for providing interference information performed in a base station comprise obtaining information about at least one intra-cell interference signal interfering desired signals of a victim terminal, and transferring the information about at least one intra-cell interference signal to the victim terminal. In the method, the information about at least one intra-cell interference signal may include either information related to generation of reference signal for the at least one intra-cell interference signal or frequency resource allocation information and precoding matrix indicator (PMI) allocation information for the at least one intra-cell interference signal. Thus, the victim terminal may operate an advanced receiver based on the received information thereby canceling interferences efficiently.
