    摘要： Apparatus and method for performing Automatic Retransmission request (ARQ) in a wireless relay communication system are provided, which include performing ARQ with the base station (BS), transmitting data successfully received from the BS to mobile station (MS), and retransmitting corresponding data to the MS when a retransmission indication message is received from the BS. Since the relay station (RS) relays only the errorless data to the receiver, the reliability of the data received at the receiver can be enhanced. The load on the RS can be reduced because the transmitter controls the ARQ.

    摘要： A method for managing flow information of a mobile station by a target base station in a communication system is provided. The method includes receiving a ranging request message, which includes a flow identifier for each of flows between a serving base station and the mobile station and a change count indicating the number of times of an addition/change/deletion operation of a corresponding flow for each of flow identifiers, from the mobile station; and transmitting a ranging response message, which includes a validity indicator indicating whether the change count of each of the flow identifiers is valid or not, to the mobile station, wherein, when the validity indicator indicates that at least one change count among change counts for each of the flow identifiers is not valid, the ranging response message includes a list including the at least one change count that is not valid.

    摘要： Provided are an apparatus and a method for providing a concurrent data service to an Mobile Station (MS) through a plurality of heterogeneous networks. In a method for providing a data service to an MS through different wireless networks, the MS measures channel qualities of at least one accessible wireless network (913) and reports the measured channel qualities to an Internet Protocol (IP) packet controller (914). The IP packet controller selects wireless networks for data transmission on the basis of the reported channel qualities (918), distributes data destined for the MS (919), and transmits the distributed data to the selected wireless networks (920). The selected wireless networks receive the data from the IP packet controller and transmit the received data to the MS (922). The MS combines and interprets the data received from the selected wireless networks (923,924). Accordingly, it is possible to provide a seamless data service to the MS in service environments with a mixture of different wireless communication systems.

    摘要： Provided is an apparatus and method for communicating a frame in a multi-hop relay cellular communication system. When communicating at a Relay Station (RS), a Downlink (DL) signal is received from a Base Station (BS) and the received DL signal is reconfigured during a first section of a frame. The reconfigured DL signal is transmitted to a Mobile Station (MS) during a second section of the frame. During a third section of the frame, a UL signal is received from the MS and is reconfigured. The reconfigured UL signal is transmitted to the BS during a fourth section of the frame. The RS recovers data from the BS to retransmit only specific data corresponding to the BS.
