摘要： A method for indicating a synchronization signal period and an apparatus are provided. In the solutions, a base station indicates a synchronization signal period to a terminal, and after determining the synchronization signal period, the terminal receives a synchronization signal of a corresponding beam according to the synchronization signal period. No blind detection needs to be performed for the synchronization signal. Therefore, disadvantages of poor synchronization performance and relatively high power consumption in a current process of accessing a cell by the terminal are avoided.
