Problems solved by technology

[0003] The synchronization block carries PSS (Primary Synchronization Signal, primary synchronization signal), SSS (Subsidiary Synchronization Signal, secondary synchronization signal) and PBCH (Physical broadcast channel, physical broadcast channel), wherein, SSS is used as a reference for the PBCH demodulation result, that is, in the After PBCH is demodulated, the phase of the PBCH demodulation result can be adjusted according to SSS, but it is not accurate enough to adjust only according to SSS

Abstract

The present disclosure relates to a signal transmission method, including: determining a target device; transmitting a 5G signal to the target device, the 5G signal includes a synchronization block, and the synchronization block is used to carry a physical broadcast channel, a primary synchronization signal, a secondary A synchronization signal and a demodulation reference signal; wherein, the demodulation reference signal and the secondary synchronization signal are used as a reference for a demodulation result of the physical broadcast channel. By further setting the demodulation reference signal in the synchronization block, both the auxiliary synchronization signal and the demodulation reference signal can be used as a reference for the demodulation result of the physical broadcast channel, so as to ensure that the phase of the adjusted demodulation result is the same as that of the transmission device before modulation The phases of the sync blocks are the same as possible, which greatly eliminates the influence of factors such as the Doppler effect on the sync block phase during signal transmission.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular, to a signal transmission method, a signal transmission device, an electronic device, and a computer-readable storage medium. Background technique [0002] At present, in the 5G (fifth generation mobile communication technology) standardization process of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project), signals and channels are mainly carried by synchronization blocks, and transmitted by transmitting synchronization blocks to user equipment. Signal. [0003] The synchronization block carries PSS (Primary Synchronization Signal, primary synchronization signal), SSS (Subsidiary Synchronization Signal, secondary synchronization signal) and PBCH (Physical broadcast channel, physical broadcast channel), wherein, SSS is used as a reference for the PBCH demodulation result, that is, in the After the PBCH is demodulated, the phase of the PBCH de...
