Problems solved by technology
[0007] At the receiving terminal, for a synchronization source around it, it is necessary to receive a maximum of 8 or 64 synchronization signal blocks in one synchronization period. If the receiving terminal has multiple synchronization sources, such as 5 synchronization sources, it needs to receive And after decoding 5*64 synchronization signal blocks, the synchronization source with the highest synchronization priority can be judged and used as a synchronization reference for the terminal on the receiving side, which will bring huge receiver complexity and synchronization detection delay

The invention discloses a method for determining a synchronization reference source and a terminal. The method for determining a synchronization reference source includes: detecting a direct link-primary synchronization signal S-PSS and a direct link-secondary synchronization signal S-SSS sent by a synchronization source The first indication information carried, or by detecting the first indication information carried by the through link-primary synchronization signal S-PSS and the through link-secondary synchronization signal S-SSS sent by the synchronization source and the physical synchronization signal sent by the synchronization source Obtain the synchronization priority information of the synchronization source from the second indication information carried by the demodulation reference signal DMRS corresponding to the direct link broadcast channel PSBCH; determine the synchronization priority information of the synchronization source and the first measurement information according to the synchronization priority information of the synchronization source The synchronization reference source of the terminal on the receiving side. The scheme of the present invention enables the terminal to obtain synchronization priority information before decoding the PSBCH, reduces the complexity of synchronization detection, simplifies the synchronization detection process, and accelerates the synchronization detection speed.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and a terminal for determining a synchronization reference source. Background technique [0002] In a 5G NR (NR Radio Access, new radio access technology) V2X system, a PC5 port (Sidelink, straight-through link) is used for direct communication between terminals. Before the service data transmission, the synchronization between the two terminals that need to be communicated is established on the PC5 port (Sidelink). The method of establishing synchronization is that one terminal A sends the synchronization and broadcast signals, and the other terminal B receives the synchronization and broadcast signals sent by terminal A. Once the terminal B receives and demodulates successfully, the two terminals can establish synchronization, which is directly used for the next step. Communication is ready. [0003] The synchronization signal of the NR UU port ...
