    • The present invention relates to a method and an apparatus for transmitting and receiving data in a relay communication system. The method and the apparatus allocate resources by dividing backhaul link resources into plural partitions, and then transmit and receive data. The data transmission method of the invention comprises the steps of: allocating a certain number of initial OFDM symbol transmission periods in a sub-frame of a downlink channel to a control channel that transfers the control information of the terminal, wherein data is transmitted from a base station to a relay or terminal through the downlink channel; dividing the resource blocks excluded from the control channel of the sub-frame into at least two partitions based on frequency domain; determining whether or not each divided partition is allocated to the relay or terminal as resources; and allocating data to the determined partition in order to transmit the partition to the relay or terminal through the downlink channel, wherein the partition determined for the allocation of resources to the relay is allocated to the relay through time division multiplexing (TDM) or frequency division multiplexing of both control and data channels of the relay.
    • 本发明涉及在中继通信系统中发送和接收数据的方法和装置。 该方法和装置通过将回程链路资源分成多个分区,然后发送和接收数据来分配资源。 本发明的数据传输方法包括以下步骤:在下行链路信道的子帧中将一定数量的初始OFDM符号传输周期分配给传送终端的控制信息的控制信道,其中数据从 基站通过下行链路信道到中继或终端; 将从子帧的控制信道排除的资源块划分为基于频域的至少两个分区; 确定每个划分的分区是否作为资源分配给中继站或终端; 并且将数据分配给所确定的分区,以通过下行链路信道向中继站或终端发送分区,其中通过时分多路复用(TDM)或分频将分配给中继的资源确定的分区分配给中继 继电器的控制和数据通道的复用。
