|1. (WO2018103638) DATA TRANSMISSION METHOD, SENDING DEVICE, RECEIVING DEVICE AND COMMUNICATION SYSTEM|
|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||DATA TRANSMISSION METHOD, SENDING DEVICE, RECEIVING DEVICE AND COMMUNICATION SYSTEM|
Disclosed are a data transmission method, sending device, receiving device and communication system. The sending device is used for sending a first transmission block, wherein the sending device acquires an encoded bit segment from a first encoded code block, the first encoded code block being obtained by means of performing, according to processing capacity of a receiving device, LDPC encoding on a first code block in the first transmission block; and the sending device sends the encoded bit segment to the receiving device. Since the processing capacity of the receiving device is taken into consideration, the storage overhead of the sending device or the receiving device can be reduced, and the complexity of encoding or decoding is reduced, thereby improving the success rate of decoding.
