    • PURPOSE: A data transceiving apparatus and method using a relay device in a wireless communications system based on centralized control type MAC(Media Access Control) are provided to transmit and receive smoothly data by using a relay path through the relay device even in case the condition of a channel is not good, or a direct path on LOS(Line of Sight) between devices is cut off. CONSTITUTION: The channel condition of a communications path with a corresponding device and a communications path through a relay device are determined. According to the channel conditions of the communications paths, one or more paths are selected(S1201). Data is transmitted and received through the selected paths(S1203). In case the selected path is cut off, or channel condition information is lower than a preset threshold value, the other communications path is reselected(S1205,S1207). The data is transmitted and received through the reselected path(1209).
    • 目的:提供一种基于集中控制型MAC(媒体访问控制)的无线通信系统中的中继装置的数据收发装置和方法,通过使用通过中继装置的中继路径平滑发送数据,即使在条件 的通道不好,或者设备之间的LOS(视线)的直接路径被切断。 规定:确定通过相应设备的通信路径和通过中继设备的通信路径的信道状况。 根据通信路径的信道条件,选择一个或多个路径(S1201)。 通过选择的路径发送和接收数据(S1203)。 在所选择的路径被切断或信道条件信息低于预设阈值的情况下,重新选择另一通信路径(S1205,S1207)。 通过重选路径(1209)发送和接收数据。
