    • PURPOSE: An apparatus and a method for re-transmitting an error generation packet data are provided to decrease a data transmission time by re-transmitting corresponding packet data in a physical layer when an error is generated in transmitted packet data. CONSTITUTION: Packet data are transmitted from a transmission side of physical layers, and packet data of the last transmitted frame is simultaneously stored re-transmission butters(S10). Timers of the physical layers are operated for counting a certain set time(S20). It is judged whether a response signal in which the transmitted packet data are received without an error is received from the physical layers(S30). If the response signal is not received from the physical layers, it is judged whether the counting of the timers is ended(S40). If the counting of the timers is ended, the packet data stored in the re-transmission butters are retransmitted to a receiving side(S50).
    • 目的:提供一种用于重传错误生成分组数据的装置和方法,用于通过在发送的分组数据中产生错误时通过重新发送物理层中的相应分组数据来减少数据传输时间。 构成:从物理层的发送侧发送分组数据,同时存储最后发送的帧的分组数据再发送对象(S10)。 操作物理层的定时器用于计数一定的设定时间(S20)。 从物理层接收是否接收到没有错误地发送的分组数据的响应信号(S30)。 如果没有从物理层接收到响应信号,则判断定时器的计数是否结束(S40)。 如果定时器的计数结束,则将存储在重新发送接收器中的分组数据重发到接收侧(S50)。
