Abstract: A power control method and a communications apparatus, in which the method includes: obtaining, by a terminal device, slot format information (SFI) of a target slot in a non-serving cell; and determining, by the terminal device based on the SFI, a power control parameter set used by the terminal device to send data in the target slot in a serving cell, where the power control parameter set belongs to a set of power control parameter sets configured for the terminal device. According to the power control method provided in this application, when a time domain resource conflict exists between the serving cell and the non-serving cell of the terminal device, the terminal device may determine an uplink power control parameter set of the serving cell of the terminal device by using the obtained SFI that dynamically changes in the non-serving cell.
