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.

Abstract: A dynamic resource allocating apparatus of a first base station that manages a first cell in a cellular communication system including the first cell and a plurality of cells adjacent to the first cell determines time resource division vector in which one time resource division period is formed of a plurality of time division intervals and calculates time resource division vector for maximizing utilities of user terminals in a set up objective function to update the time resource division vector. Among the plurality of time division intervals, a first time division interval is operated by a time resource reuse coefficient 1 for user terminals positioned in center regions of a first cell and a plurality of adjacent cells, and the remaining time division intervals excluding the first time division interval are operated by a time resource reuse coefficient n for user terminals positioned at edges of the first cell and the plurality of adjacent cells.
