    • Provided are an apparatus and method for transmitting data and an apparatus and method for receiving data, in which the transmission of uncompressed data over a wireless network can be performed by retransmitting an erroneous bit or a group of erroneous bits, if any, of each sub-packet including a number of bits or a number of groups of bits having different significance levels. The apparatus for transmitting data includes an error detection module which determines whether each of a plurality of portions of a transmitted packet having different significance levels is erroneous based on a received response packet; a data-packet generation module which generates a retransmission packet including one or more erroneous portions of the transmitted packet according to the results of the determination performed by the error detection module; and a communication module which transmits the retransmission packet through a communication channel.
    • 提供了一种用于发送数据的装置和方法以及用于接收数据的装置和方法,其中通过无线网络传输未压缩数据可以通过重传每个子帧的错误位或一组错误位(如果有的话)来执行 包括多个比特或多个具有不同重要性级别的比特组。 用于发送数据的装置包括:错误检测模块,其基于接收到的响应分组来确定具有不同有效级别的发送分组的多个部分中的每一个是否是错误的; 数据分组生成模块,根据由所述错误检测模块执行的判定结果,生成包含所发送分组的一个以上的错误部分的重发分组; 以及通过通信信道发送重发分组的通信模块。
