Title:
SIGNAL TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/100456
Kind Code:
A1
Abstract:
The present application provides a signal transmission method and apparatus. The method comprises: a cooperative device receives a synchronization trigger frame sent by a central device; the cooperative device obtains time domain offset information and/or frequency domain offset information; the cooperative device sends a signal by means of a corresponding time domain resource and frequency domain resource according to the synchronization trigger frame, and the time domain offset information and/or the frequency domain offset information. In this way, time domain resources and/or frequency domain resources sent to a same terminal by multiple cooperative devices are different, and interference signals in channel estimation can be removed; thus, the effect of improving the channel estimation and noise estimation accuracy at the receiving end can be achieved, thereby improving the demodulation performance at the receiving end and the throughput rate of the whole network.
