Patent ID: RE43930

Claim:
In a method for respective base stations of a plurality of cells to configure forward channels transmitted to a mobile station in an FDD (frequency division duplex) based mobile communication system, a forward channel configuring method comprising: (a) classifying the cells into a specific number of interference patterns based on location relations of the respective cells; (b) preventing the respective base stations of the cells having different classified patterns to sequentially transmit control information to the mobile station during different defined periods within a period of the forward channel, and allowing the respective base stations of the cells having the same classified patterns to concurrently transmit control information to the mobile station exclusively during one of the defined periods; and (c) allowing the respective base stations to transmit traffic data to the mobile station irrespective of the classified patterns when the control information is transmitted in (b), wherein (a) comprises classifying the cells, which have less inter-cell interference since the cells are not adjacent, as those having the same pattern.
