Abstract: This application provides an uplink signal sending method, an apparatus, and a system, and generally relates to the field of communications technologies. The uplink signal sending method includes obtaining first indication information, and determining, based on the first indication information, whether to send an uplink signal on a supplementary uplink (SUL) or an uplink (UL). The first indication information is used to indicate a SUL available time, and the SUL available time is a time in which an uplink signal can be sent on an SUL carrier in a preset period. The method is applied to a procedure in which an uplink signal is sent by using an uplink carrier, to improve flexibility in an uplink signal sending process.
