Hybrid Automatic Repeat Request Method and Related Apparatus

摘要

A hybrid automatic repeat request method includes receiving a packet sent by a transmit end; checking N data sub-blocks included in the packet, and generating feedback information according to a check result, where the feedback information includes N check characters corresponding to the N data sub-blocks, and the check character is an acknowledgment character ACK or a negative acknowledgment character NACK; and returning the feedback information to the transmit end. In technical solutions of the present disclosure, feedback information that includes N check characters corresponding to N data sub-blocks of a packet is used and the feedback information is returned to a transmit end, so that a data sub-block can be selected, according to the negative acknowledgment character NACK, to perform retransmission. Therefore, the transmit end can adaptively retransmit a data sub-block having an error, thereby improving resource utilization and reducing a transmission delay.
