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.
