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 translation: 提供了一种通过形成光束的单向协作通道来连接基站的方法。 由于可以通过少量的计算来确定波束的方向和分配功率分量，所以可以以小的费用在单向协作状态下实现基站。 此外，根据本发明的示例性实施例的基站可以最小化由其他基站通过单向协作信道发送的信号产生的干扰的影响以及由发送到其他终端的信号产生的干扰的影响。
