    • The present invention relates to a broadband wireless access system, and more particularly, a ranging technique of a terminal using a legacy support frame in a mobile communication system including a legacy system and an advanced system. According to one form of an embodiment of the present invention, the ranging method of the terminal for a base station in the mobile communication system having the legacy system and the advanced system comprises the steps of: receiving secondary super frame header (S-SFH) information from the base station; determining whether a frame composition used in the mobile communication system supports the legacy system; acquiring ranging channel information for initial ranging, handover ranging, and periodical ranging from the S-SFH; and performing one or more ranging processes of the initial ranging, the handover ranging, and the periodical ranging in the base station by using the ranging channel information.
    • 宽带无线接入系统技术领域本发明涉及一种宽带无线接入系统,更具体地说,本发明涉及在包括传统系统和高级系统的移动通信系统中使用传统支持帧的终端的测距技术。 根据本发明的实施例的一种形式,具有遗留系统和高级系统的移动通信系统中的基站终端的测距方法包括以下步骤:接收第二超帧头(S-SFH) 来自基站的信息; 确定在移动通信系统中使用的帧组合是否支持传统系统; 从S-SFH获取初始测距,切换测距和定期测距的测距信道信息; 并通过使用测距信道信息来执行初始测距,切换测距和基站中的周期测距的一个或多个测距过程。
