    • An apparatus and method for re-transmitting erroneous packet data is disclosed. Each of the physical layers of the system includes a buffer, a timer, a controller, and a radio frequency unit. The buffer temporarily stores transmitted data in the form of a final data frame capable of being transmitted on a transmission line without any processing. The timer is a time counter adapted to limit the time, for which the transmission end waits for an acknowledgment to a transmission of data after the data transmission is made. If no acknowledgment signal is received when the timer expires the buffered data in the physical layer is re-transmitted. This reduces the data transmission delay resulting from the inter-layer movement of data generated during a re-transmission of erroneous data, and the transmission delay of packet data resulting from overhead time.
    • 公开了重传错误分组数据的装置和方法。 系统的每个物理层包括缓冲器,定时器,控制器和射频单元。 缓冲器临时存储能够在传输线上传输的最终数据帧形式的发送数据,而不进行任何处理。 定时器是一种时间计数器,适用于限制传输结束在进行数据传输之后等待数据传输确认的时间。 如果在定时器到期时没有接收到确认信号,物理层中缓存的数据被重新发送。 这减少了在错误数据的重新传输期间产生的数据的层间移动以及由开销时间产生的分组数据的传输延迟所导致的数据传输延迟。
