Abstract: Embodiments of this application relate to the communications field, and provide a data transmission control method. The method includes: obtaining, by the first communications apparatus, radio frequency signals; processing, by the first communications apparatus, at least two parts of signals in the radio frequency signals in at least two functional split manners, to generate at least two parts of transmission signals, where each part of signals in the radio frequency signals is processed in one functional split manner, and different parts of signals in the radio frequency signals are processed in different functional split manners; and sending, by the first communications apparatus, the at least two parts of transmission signals to the second communications apparatus.

Abstract: This application provides a phase correction method and a communication apparatus. In the phase correction method, a network device sends a combined signal to a terminal, where the combined signal is obtained by passing a first signal through N channels and combining output signals of the N channels. The terminal determines a precoding matrix based on the combined signal and feeds back the precoding matrix to the network device. The network device estimates a phase error between a plurality of channels of the network device based on the precoding matrix, and corrects phases of the N channels based on the obtained phase error. In the foregoing technical solution, soft correction of phases of N channels of the network device may be implemented by using an air interface feedback of a terminal, so that it can be ensured that the phases of the N channels are consistent.
