Abstract: A method and an apparatus for transceiving data are provided to reduce a queuing delay of data by maximizing use of a BSN(Block Sequence Number). A transmitter assigns a BSN to each block(S602). The transmitter transmits 0~9 blocks to a receiver(S604). The receiver generates ACK(Acknowledgement) and NACK(Non-Acknowledgement)(S608,S610). The ACK/NACK is transmitted to the transmitter(S612). The transmitter assigns the BSN to a new SDU(Service Data Unit) block as the number of blocks which receives the ACK(S614). ARQ-TX-NEXT-BSN is updated(S616). The receiver stores the received data block in a DATA Q(S622,S624). The receiver moves the block having the BSN to the DATA Q belonging to a Window range(S626,S628). The ACK/NACK is transmitted to the transmitter(S630,S632). The transmitter transmits the new SDU block including the new BSN(S634).

Abstract: A method for allocating resources and a method for receiving data are provided to control a transmission error of data received through a relay station uplink dedicated channel. A base station transmits a resource allocating message to a relay station(S310), and receives a receiving confirmation message about the resource allocating message from the relay station(S320). The receiving confirmation message is included in a header of a relay station uplink dedicated channel. The base station confirms success of a resource allocation in receiving the receiving confirmation message(S340). If the base station does not receive the receiving confirmation message about the resource allocating message from the relay station, the base station retransmits the resource allocating message to the relay station(S330).
