    • PURPOSE: A management frequency band sharing method of heterogeneous wireless communication system and a system thereof are provided to manage power saving method of a terminal within a service zone in a AP(Access Point) of a Wi-FI system, thereby managing data transmission of the terminal. CONSTITUTION: A transmission section of a first wireless communication system(141) is assignment within a frame section of a second wireless communication system. A terminal is operated in a power saving method in a transmission method of a second wireless system. The terminal transmits data only in the transmission interval of a first wireless communication system. The transmission interval is assigned following a downlink section of a second communication system. In other words, the transmission interval is assigned before a uplink section of a second communication system.
    • 目的:提供异构无线通信系统的管理频带共享方法及其系统,以管理Wi-Fi系统的AP(接入点)内的服务区内的终端的节能方法,由此管理数据传输 终点站。 构成:第一无线通信系统(141)的发送部分是在第二无线通信系统的帧部分内的分配。 在第二无线系统的发送方法中,以省电方式操作终端。 终端仅在第一无线通信系统的发送间隔中发送数据。 在第二通信系统的下行链路部分之后分配传输间隔。 换句话说,在第二通信系统的上行链路部分之前分配传输间隔。

    • PURPOSE: An apparatus and a method for separating signals of different systems in a wireless communication system are provided to efficiently separate the signal of different kinds of systems by discriminating a transmission signal from a reception signal in each system and adjusting transmission and reception timing. CONSTITUTION: The reception signals of first and second systems are received through an antenna connected to a first terminal, and a circulator(202) outputs the transmission signals of the first and second systems, which are inputted to a third terminal, to the first terminal. A first reception filter(204-1) filters the signal outputted from a second terminal of the circulator to a reception band of the first system. A second reception filter(204-2) filters the signal outputted from the second terminal to the reception band of the second system.
    • 目的:提供一种用于在无线通信系统中分离不同系统的信号的装置和方法,以通过从每个系统中的接收信号辨别发送信号并且调整发送和接收定时来有效地分离不同种类的系统的信号。 构成:第一和第二系统的接收信号通过连接到第一终端的天线接收,循环器(202)将输入到第三终端的第一和第二系统的传输信号输出到第一终端 。 第一接收滤波器(204-1)将从循环器的第二端子输出的信号滤波到第一系统的接收频带。 第二接收滤波器(204-2)将从第二终端输出的信号滤波到第二系统的接收频带。
