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: Embodiments of this application relate to a PRACH detection method, and the method includes: sequentially detecting frequency domain data of each beam in at least two groups of beams; obtaining frequency domain data of a frequency corresponding to a PRACH from frequency domain data of a currently detected beam; determining a time domain correlation peak of the PRACH based on the frequency domain data of the frequency corresponding to the PRACH; determining a first peak value based on the time domain correlation peak of the PRACH; and when the first peak value is greater than or equal to a first threshold, sending a random access response message to user equipment.
