Abstract: A method of connecting base stations by a one-way cooperative channel forming a beam is provided. Since it is possible to determine directions of beams and to distribute power components by small amounts of calculations, it is possible to realize the base stations in a one-way cooperative situation with small expenses. In addition, the base stations according to the exemplary embodiment of the present invention may minimize the influence of interference generated by signals transmitted by other base stations through the one-way cooperative channel and the influence of interference generated by signals transmitted to other terminals.
