Abstract
A method for restraining inter-cell interference in a mobile communication system is provided. The method uses the fast dynamic selection of the Fractional Frequency Reuse (FFR) technology and the Macro Diversity (MD) technology of the cell edge to increase the cell edge user data rate and provide excellent system capacity. The method is particularly suitable in a OFDMA mobile communication system downlink. The method comprises the steps of: (a) determining whether the cell edge user is able to operate the MD technology; (b) processing the fast dynamic selection of the FFR technology and the MD technology for the cell edge user, and the selection is made based on a instantaneous link Signal Quality Index (SQI); and (c) allocating the center subband or the edge subband to the cell edge user according to the selection.
