摘要： 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.

摘要： The present invention relates to a method and apparatus for data transmission, which properly use the time slot between a downlink transmission period and an uplink transmission period for a backhaul communication between a base station and a relay node in a time division multiplexing communication system. The method for data transmission in a relay communication system according to one embodiment of the present invention comprises the steps of: setting a data frame including a downlink subframe for transmitting a downlink signal, an uplink subframe for transmitting an uplink signal, and a special subframe existing between the downlink subframe and the uplink subframe; and transmitting/receiving data to/from the relay node or a terminal via the data frame set in the previous step. The special subframe includes a first transmission period and a second transmission period. The downlink signal is transmitted to the relay node or the terminal via the first transmission period, and the downlink signal is transmitted to the relay node via the second transmission period, and the terminal does not perform a reference signal decoding process during the second transmission period. Therefore, interference which may occur in the backhaul communication between the base station and the relay node can be minimized, the transmission volume of the backhaul communication between the base station and the relay node can be dynamically adjusted, and the backward compatibility between the present invention and conventional wireless communication systems and conventional terminals can be maintained at a maximum level.
