The signal transmission method and the apparatus may be used in a communication system. The method includes: A terminal obtains first information, and sends a signal corresponding to a first pilot pattern or a second pilot pattern. The first information indicates the terminal to use the first pilot pattern or the second pilot pattern. The first pilot pattern indicates that a first reference signal is located at a first time domain position, and a second reference signal is located at a second time domain position. The second pilot pattern indicates that a third reference signal is located at the first time domain position, and a fourth reference signal is located at a third time domain position. A time domain interval between the first time domain position and the second time domain position is less than or greater than a time domain interval between the first time domain position and the third time domain position. A value corresponding to the first reference signal in a first precoding sequence is opposite to a value corresponding to the third reference signal in a second precoding sequence.
