The present disclosure relates to signal transmission methods and apparatus. One example method includes detecting signals in a plurality of synchronization signal blocks, where each of the plurality of synchronization signal blocks includes a first synchronization signal, a second synchronization signal, and a broadcast signal, and where at least one type of signal in each synchronization signal block and another type of signal in the same synchronization signal block are sent on non-adjacent symbols, and obtaining the signals in the plurality of synchronization signal blocks.
