Title: SIGNAL TRANSMISSION METHOD, DEVICE, ELECTRONIC APPARATUS, AND COMPUTER READABLE STORAGE MEDIUM
Abstract:
The present disclosure relates to a signal transmission method, comprising: determining a target apparatus; transmitting to a target apparatus a 5G signal comprising a synchronization block configured to carry a physical broadcast channel, a primary synchronization signal, a secondary synchronization signal, and a demodulation reference signal, wherein the demodulation reference signal and the secondary synchronization signal are configured to be used as a reference for a demodulation result of the physical broadcast channel. By further providing the demodulation reference signal in the synchronization block, the present invention enables the secondary synchronization signal and the demodulation reference signal to serve as a reference for a demodulation result of the physical broadcast channel, thus ensuring a substantial consistency between the phase of an adjusted demodulation result and the phase of the synchronization block before modulation of a transmitting apparatus, and significantly eliminating influences of various factors, such as the Doppler effect, on the phase of the synchronization block during a signal transmission process.
