Abstract: An uplink determining method and an apparatus. An access network device may determine, based on signal quality of a downlink frequency band corresponding to a supplementary uplink (SUL) or signal quality of a frequency band of an SUL, the signal quality of the frequency band of the SUL, to accurately evaluate coverage performance of the SUL; and after determining the signal quality of the frequency band of the SUL, may determine whether to perform transmission on the supplementary uplink, to avoid a case in which the access network device blindly indicates a terminal to perform transmission on the supplementary uplink when signal quality of the supplementary uplink is not measured, leading to transmission of the terminal on the supplementary uplink with poor coverage and even a failure, thereby improving reliability and a transmission rate of uplink transmission and improving user experience.
