    摘要： An apparatus and a method for transmitting an Automatic Repeat reQuest (ARQ) block in a wireless communication system are provided. The method for transmitting the ARQ block includes when transmitting the ARQ block to a receiving stage in a Not Sent state, transitioning to an Outstanding state to wait to receive one of an ACK and a NACK for the ARQ block, when receiving the NACK for the ARQ block from the receiving stage in the Outstanding state, transitioning to a Waiting for Retransmission state, when determining to retransmit the ARQ block for the NACK by splitting the ARQ block into at least two ARQ sub-blocks in the Waiting for Retransmission state, transitioning to a Rearrangement state, retransmitting the ARQ block for the NACK by splitting the ARQ block into at least two ARQ sub-blocks in the Rearrangement state, and when receiving an ACK for every ARQ sub-block having the same ARQ Sequence Number (SN) in the Rearrangement state, transitioning to a Done state and finishing transmission of the ARQ block having the ARQ SN.

    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： 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.
