Abstract: This application provides a signal transmission method and apparatus. The method includes: generating a synchronization signal block, where the synchronization signal block includes a synchronization signal and a broadcast signal, a sequence number of the synchronization signal block is indicated by using at least one of sequence number indication information carried in the broadcast signal, a scrambling code of the broadcast signal, a cyclic redundancy check CRC mask of the broadcast signal, a bijective transformation parameter of the broadcast signal, cyclic shift information of the broadcast signal on which channel coding has been performed, and a system frame number carried in the broadcast signal, and the sequence number indicates a location of the synchronization signal block in a plurality of synchronization signal blocks; and sending the synchronization signal block.
