Title: INFORMATION TRANSMISSION METHOD, RECEIVING DEVICE, TRANSMITTING DEVICE, AND SYSTEM
Abstract:
Disclosed in an embodiment of the invention are an information transmission method, a receiving device, a transmitting device, and a system. The method comprises: receiving, by a receiving device, encoded data retransmitted at the ith time; acquiring a transmission serial number RvCnt(i) of the ith retransmission; determining, according to the transmission serial number RvCnt(i) of the ith retransmission, a redundant version Rv(i) of the ith retransmission; integrating, according to the redundant version Rv(i) of the ith retransmission, the encoded data retransmitted at the ith time into a virtual circular buffer of a data block; and performing decoding. The method of the invention eliminates the limitation imposed by the number of existing redundant versions, such that a column start position of encoded data retransmitted each time in a virtual circular buffer can be determined flexibly, thereby meeting the requirement of a high transmission bit rate. Also disclosed are a receiving device, a transmitting device, and an information transmission system.
