    • The present invention relates to a method for performing terminal cooperative transmission through direct link communication between a source terminal that requests terminal cooperation and a cooperative terminal that performs the terminal cooperative transmission with the source terminal in a wireless access system, and the method comprises the steps of allowing the source terminal to transmit a terminal cooperation request message for requesting the terminal cooperative transmission to a base station, allowing the base station to transmit control information for establishing a direct link between the source terminal and the cooperative terminal to the source terminal, and allowing the source terminal to establish a direct communication link with the cooperative terminal, on the basis of the received control information, wherein the control information contains dedicated random access channel (RACH) allocation information for synchronization between the source terminal and the cooperative terminal and for channel measurement, and dedicated random access channel (RACH) preamble sequence information.
    • 本发明涉及一种通过在无线接入系统中请求终端协作的源终端与执行终端协作传输的协作终端之间的直接链路通信进行终端协作传输的方法,该方法包括以下步骤 允许源终端向基站发送用于请求终端协作传输的终端协作请求消息,允许基站向源终端发送用于建立源终端与协作终端之间的直连链路的控制信息,以及 允许源终端基于接收到的控制信息与协作终端建立直接通信链路,其中控制信息包含用于源终端和协作终端之间同步的专用随机接入信道(RACH)分配信息 终端和信道测量,以及专用随机接入信道(RACH)前导序列信息。
