基于差错控制编码的提高重传时信道利用率的方法及装置制造方法及图纸

本发明专利技术中发送设备如果判断需要重传已向接收设备发送的信息序列，则分别对重传信息序列以及新增信息序列进行差错控制编码，以分别生成差错控制编码后的重传生成码字和差错控制编码后的新增生成码字，对重传生成码字和新增生成码字进行逻辑运算操作，以获得经过逻辑运算的逻辑组合码字，再将该逻辑组合码字发送至所述接收设备；接收设备根据第一次接收到的码字和本次接收到的逻辑组合码字所构成的长码进行联合解码，以获取重传的信息序列和新增的信息序列。通过采用本发明专利技术提供的技术方案，发送设备在重传时，在同样的信道带宽下，不仅重传了重传信息序列，还包含了一部分新增信息序列，从而提高了信道利用率。

Method and device for improving channel utilization during retransmission based on error control coding

The invention of the sending device if the judge need to retransmit information sequence receiving device sends, respectively to the retransmission information sequence and error control encoding new information sequence, to generate new codeword retransmission generated code and error control encoding respectively generate error control encoding after operation, logic operation of retransmission the new generation of code and generate code, to get through a logical combination of codeword logical calculation, then the logic combination codeword is transmitted to the receiving device; receiving equipment for joint decoding based on the long code which first received codeword and the received logical combination of codewords, in order to obtain the retransmission of information sequence and the new information sequence. The technical scheme provided by the invention of the transmitting device in the retransmission, the channel bandwidth is the same, not only the retransmission retransmission sequence information, also includes a part of the new information sequence, so as to improve the channel utilization rate.
