Zusammenfassung:	Embodiments of the present invention disclose an information transmission method, a receiving device, a sending device, and a system. The method includes: receiving, by a receiving device, coded data of i th retransmission; obtaining a transmission count RvCnt(i) of the i th retransmission; determining a redundancy version Rv(i) of the i th retransmission based on the transmission count RvCnt(i) of the i th retransmission; combining the coded data of the i th retransmission into a virtual circular buffer of a data block based on the redundancy version Rv(i) of the i th retransmission; and performing decoding. The method may not be limited by a current quantity of redundancy versions. Therefore, a column starting position of coded data of each retransmission in the virtual circular buffer can be flexibly determined, and a requirement of a high transmission code rate is met. The present invention further discloses a receiving device, a sending device, and an information transmission system.
