    Abstract: Embodiments of this application disclose a signal transmission method, a terminal device, and an access network device, to increase a probability of sending a signal on an unlicensed spectrum resource. The method may include determining, by a terminal device, that permission to use a channel is obtained at any time point within a time window, a start time point of the time window is a start time point of a symbol, an end time point of the time window is a second time point, the second time point is within a time occupied by the symbol, a signal includes at least an actual cyclic prefix and an information segment, duration of the actual cyclic prefix is less than or equal to a time length between the start time point of the symbol and the second time point. The method may also include sending, by the terminal device, the signal from the first time point.
