    • The present invention provides a mobile communication system based on cooperative communication that prevents performance degradation when there is a time difference between a point of time when an MCS level is measured between a relay and a terminal and a point of time when an AMC is applied based thereon. The mobile communication system based on cooperative communication according to the present invention includes a base station, a relay, and a terminal. The base station determines map information between the relay and the terminal based on channel information received from the terminal through the relay. The received channel information includes information with respect to an MCS level. The base station delivers the information with respect to the raised MCS level to the relay when a rise in the MCS level is required. In other words, the base station can control the MCS level by delivering an MCS level control signal to the relay. In order to prevent data loss that may occur when the MCS level is raised, the base station delivers the same data as the relay to the terminal during the period of time when the MCS level is changed and thus a macrodiversity gain can be obtained.

    • 本发明提供了一种基于协作通信的移动通信系统,当在中继站和终端之间测量MCS级别的时间点与基于应用AMC的时间点之间存在时间差时,防止性能下降 在其上。 根据本发明的基于协作通信的移动通信系统包括基站,中继站和终端。 基站基于通过中继从终端接收到的信道信息确定中继站与终端之间的映射信息。 所接收的频道信息包括关于MCS级别的信息。 当需要MCS级别的上升时,基站将相对于提高的MCS级别的信息传递给继电器。 换句话说,基站可以通过向中继发送MCS级别控制信号来控制MCS级别。 为了防止在MCS电平升高时可能发生的数据丢失,基站在MCS电平改变的时间段期间向终端传送与中继器相同的数据,从而可以获得宏分集增益。 (附图标记)(100)基站; (200)继电器; (300)码头; (AA,CC)协同通信数据,MCS控制信号; (BB,DD)频道信息; (EE)合作通信数据
