    • 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.
    • 提供了一种用于在无线通信系统中发送自动重复请求(ARQ)块的装置和方法。 用于发送ARQ块的方法包括当在未发送状态下向接收侧发送ARQ块时,转移到未完成状态以等待接收ARQ块的ACK和NACK中的一个,当接收到针对ARQ块的NACK时 ARQ块从处于未完成状态的接收阶段转移到等待重传状态,当通过在等待重传状态中将ARQ块分解为至少两个ARQ子块来确定重传用于NACK的ARQ块时,转换 通过将ARQ块分解为重排状态中的至少两个ARQ子块,并且当对具有相同ARQ序列号(SN)的每个ARQ子块接收到ACK时,重新发送用于NACK的ARQ块, 在重排状态下,转换到完成状态并完成具有ARQ SN的ARQ块的传输。
