Patent ID: 11184878

Abstract:
A signal transmission method is provided. The method includes: determining a target device, and transmitting a 5G signal to the target device, where the 5G signal includes a synchronization block, and the synchronization block is used to carry a PBCH, a PSS, an SSS and a DMRS, and the DMRS and the SSS are used as references for a demodulation result of the PBCH. By further setting the DMRS in the synchronization block, both the SSS and the DMRS are used as the references for the demodulation result of the PBCH, thereby ensuring that an adjusted phase of the demodulation result is as same as possible to a phase of the synchronization block before modulation of a transmission device, which greatly eliminates influence of factors such as the Doppler effect on the phase of the synchronization block during a signal transmission process.
