摘要： A method and device for performing an Automatic Repeat Request (ARQ) procedure in a wireless communication environment are provided. An initiation of the ARQ reset procedure is triggered by one of a transmitting device and a receiving device. A sequence number corresponding to a start of an ARQ window is determined. The sequence number is a sequence number of a first ARQ block to be transmitted by the transmitting device upon completion of the ARQ reset procedure. An ARQ reset message indicating the determined sequence number is transmitted to the receiving device. Accordingly, first and second pointer values of the ARQ window at the receiving device is set to the sequence number in the ARQ reset message. An ARQ reset acknowledgement message is sent to the transmitting device. Moreover, first and second pointer values of the ARQ window at the transmitting device is set to the determined sequence number.

摘要： The present invention provides a method and system for generating and processing medium access control (MAC) protocol data units (PDUs) in a broadband wireless network environment. In one embodiment, a method includes determining whether a MAC service data units (SDUs) intended for a receiving device includes fragmented MAC SDU(s). The method also includes generating MAC PDU(s) from the fragmented MAC SDU(s) when the MAC SDUs includes fragmented MAC SDU(s), where each MAC PDU includes a single fragmented MAC SDU. The method further includes determining whether unfragmented MAC SDU(s) in the MAC SDUs satisfy pre-defined criteria. If the unfragmented MAC SDU(s) satisfy the predefined criteria, the method includes generating MAC PDU(s) from the unfragmented MAC SDU(s), where each MAC PDU includes multiple unfragmented MAC SDUs. Otherwise, the method includes generating MAC PDU(s) from the unfragmented MAC SDU(s), where each MAC PDU includes a single unfragmented MAC SDU.

摘要： An apparatus and method for performing Uplink (UL) communication by a Relay Station (RS) in a wireless communication system are provided. The RS receives a Transmit/receive Transition Gap (TTG) and a Receive/transmit Transition Gap (RTG) of a Base Station (BS) during a network entry process of the RS, receives, from the BS, an idle time R_IdleTime between frames used in the RS, and determines a structure of a UL frame. In the alternative, the RS determines a time interval Tad or an idle time R_IdleTime according to a predetermined scheme, and transmits the Tad or the R_IdleTime to the BS. The proposed apparatus and method reduce an overhead of a frame structure when the RS transitions from a transmission mode to a reception mode or from a reception mode to a transmission mode, the frame structure being for frames of the BS and it adjacent RS, thereby reducing interference.

摘要： An apparatus and method for reduces an overhead caused by an operation transition gap in a Relay Station (RS) of a relay wireless communication system. The method includes identifying a signal delay time with an upper node. A transmission/reception operation transition time is determined through a negotiation with the upper node. An idle time is identified. An overhead caused by a transmission/reception operation transition is determined with consideration of a start time point of an Uplink (UL) subframe dependent on the signal delay time, the transmission/reception operation transition time, and the idle time. And communication is performed considering the overhead. The start time point of the UL subframe is set earlier than a start time point of a UL subframe of the upper node in consideration of the idle 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.
