Signal transmission method and apparatus

Abstract

The present disclosure provides a signal transmission method and apparatus, where the method includes: transmitting a first signal on subcarriers of a plurality of orthogonal frequency division multiplexing (OFDM) symbols, where a frequency offset of the subcarriers exists among the plurality of OFDM symbols. The present disclosure enables the first signal is no longer concentrated on the subcarriers at a specific frequency, but is dispersed more evenly. The interference of the first signal is more even for the signal being transmitted by the neighboring cell terminal device. On one hand, the influence on the data demodulation of the neighboring cell terminal device is reduced; and on the other hand, if the neighboring cell performs interference measurement, the difference in measurement results on different subcarriers is reduced and the accuracy of the interference measurement result is improved.
