1. A data transmission method, implemented on a receive end, wherein the method comprises:
evaluating a channel quality of a first channel between the receive end and a transmit end a plurality of times to obtain a plurality of evaluation results and obtaining a channel quality evaluation result, wherein the channel quality evaluation result is an average value, a minimum value, or a maximum value of the plurality of evaluation results;
determining first acknowledgement information or first negative acknowledgement information based on the channel quality evaluation result; and
sending a first response message to the transmit end at a triggering moment of a first preset condition, wherein the first response message comprises the first acknowledgement information or the first negative acknowledgement information, and wherein
when the receive end determines that the channel quality evaluation result is greater than or equal to a threshold, the receive end determines that the first response message carries the first acknowledgement information,
the first response message is used by the transmit end to determine whether to resend data previously transmitted, wherein receipt of the first response message at a first time directs the transmit end to wait for a next first response message, and receipt of two consecutive first response messages comprising the first acknowledgment information directs the transmit end to end a hybrid automatic repeat request (HARQ) process corresponding to the data.
