Abstract: This application provides a signal transmission method and apparatus. The method includes: A collaboration device receives a synchronization trigger frame delivered by a central device; the collaboration device obtains information about a time domain offset and/or information about a frequency domain offset; and the collaboration device sends a signal based on the synchronization trigger frame and the information about the time domain offset and/or the information about the frequency domain offset by using a corresponding time domain resource and a corresponding frequency domain resource. In this way, a plurality of collaboration devices send different time domain resources and/or frequency domain resources to a same terminal, and an interfering signal in channel estimation can be removed. This improves precision of the channel estimation and noise estimation at a receiving end, and improves demodulation performance at the receiving end and entire-network throughput.
