    摘要: An apparatus and a method for sending a control message for retransmission in a multihop relay wireless communication system are provided. Data received from a lower node is checked for errors. The data is transmitted to an upper node, when the data has no errors. When two or more messages, which include at least one of Acknowledgement (ACK) messages and Negative ACK (NACK) messages in response to a data reception are received from one or more lower nodes, the two or more messages are transmitted to the upper node at the same time. Accordingly, the RS can transmit the control messages for the ARQ provided from the lower nodes, to the upper node at the same time.

    摘要: Data retransmission apparatus and method in a wireless relay communication system are provided. It is checked whether an Acknowledgement (ACK) message or a Negative ACK (NACK) message for data is received from a Relay Station (RS), which receives the data from a Mobile Station (MS). Scheduling information for transmitting the data is transmitted to the RS, when the ACK message is received from the RS. Errors are checked for in of the data, when the data is received from the RS. The RS is requested to retransmit the data, when the data has an error. Accordingly, since the RS retransmits only the error-free data to the BS, the BS can enhance the data reliability.

    摘要: An apparatus and method for configuring a Relay-Frame Control Header (R-FCH) transmitted in an intermediary link area in a multi-hop relay Broadband Wireless Access (BWA) communication system are provided. The method includes determining a modulation scheme of a Relay Station (RS) Downlink (DL)-MAP (or simply referred to as R-MAP) in consideration of a channel state with the RS while an initial network entry process is performed by the RS or while communicating with the RS in a Base Station (BS)-RS area where communication is made with RSs connected to the BS and transmitting a message including the determined modulation scheme to the RS. Accordingly, a Modulation and Coding Scheme (MCS) on the R-MAP can be dynamically changed according to a channel state between an RS and a BS, thereby enabling effective use of resources.

    摘要: An apparatus and a method for processing the relayed data in a multihop relay broadband wireless access communication system are provided. A method for an operation of a Relay Station (RS) includes determining whether a packet received from an upper node comprises a Relay Media Access Control (MAC) Header (RMH), when the RMH is comprised in the received packet, determining whether the RMH comprises access RS information, and when the access RS information is not comprised in the RMH, removing the RMH from the received packet and transmitting the packet to a lower Mobile Station (MS).

    摘要: An apparatus and a method for processing a change of a preamble of a Relay Station (RS) are provided. An operating method of a Base Station (BS) includes providing a relay service via an RS, determining whether a preamble of the RS needs to change, when it is necessary to change the preamble of the RS, sending a preamble change command message to the RS and, when the preamble of the RS is changed, sending a preamble change notification message informing of the preamble change to at least one lower node of the RS.
