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.

Abstract: An uplink power control method and a communications device are described. The method includes receiving, by a terminal device, power control indication information sent by a network device. The power control indication information indicates a first power offset set, and the first power offset set is any one of at least two power offset sets. The method further includes receiving, by the terminal device, a transmit power control (TPC) command sent by the network device. The TPC indicates a first offset in the first power offset set. The method includes determining, by the terminal device, uplink transmit power based on the first offset. Impact of cross interference is considered in determining the uplink transmit power. Thus, the method can meet requirements of future mobile communications and improve system performance.

Abstract: Embodiments provide a method for transmitting a reference signal between a base station and a terminal. In this method, a parameter is determined by a terminal based on frequency domain location information of a frequency domain resource unit. The parameter is used to determine a sequence of the reference signal, and the reference signal is carried on the frequency domain resource unit. The reference signal can be sent to the base station by the terminal. In some embodiments, the reference signal sent by the base station can be received by the terminal. According to this method, a peak-to-average power ratio when a single terminal sends data to a base station can be reduced, and communication interference between different cells can be canceled or reduced as much as possible.
