    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.

    Abstract: A method for feeding back information includes: measuring a CQI of a link between each coordinated transmitting node in a coordinated transmitting node set and a terminal,; using the CQI of and an RI value corresponding to the link between each coordinated transmitting node and the terminal as parameters of a spectral efficiency calculation function, and obtaining a spectral efficiency value corresponding to the link between each coordinated transmitting node and the terminal; when a value of the selection criterion function is less than or equal to a preconfigured comparison threshold value, selecting a corresponding coordinated transmitting node as a preferred coordinated transmitting node; and sending information of the preferred coordinated transmitting node to a transmitting end for selection. This may reduce uplink feedback overheads and enable the transmitting end to quickly determine the preferred coordinated transmitting node.
