description This application provides a method for generating a pilot signal, including: obtaining, by a terminal device, a correlation identifier and a port number; determining, by the terminal device, a pilot sequence based on the correlation identifier; and generating, by the terminal device, the pilot signal based on the pilot sequence and the port number. The foregoing correlation identifier is used to indicate a manner in which the terminal device determines the pilot sequence. The foregoing manner in which the pilot sequence is determined, for example, is a manner in which a pilot sequence is determined and that is correlated with a timeslot, or the foregoing manner in which the pilot sequence is determined may be a manner in which a pilot sequence is determined and that is not correlated with a timeslot. Therefore, a requirement of different application scenarios for correlation between pilot signals may be met. The method for the pilot signal provided in this application may be applied to grant based transmission (including existing grant based transmission, and further including grant based transmission in a 5G system for mobile communications), or may be applied to grant free transmission in the 5G system for mobile communications. Therefore, the solutions provided in this application further have relatively good backward compatibility.
