A method for transmitting a synchronization signal, comprising: determining, by a base station, the synchronization signal; transmitting, by the base station, the synchronization signal determined to a receiving end, and notifying, by the base station, the receiving end of configuration information related to the synchronization signal determined; characterized in that the synchronization signal comprises X synchronization signal groups, wherein each group of the X synchronization signal groups comprises a respective one of N 1, N 2,...N x types of downlink synchronization signals, N 1, N 2,...N x types of downlink synchronization signals correspond to N 1,N 2,...N x transmission configurations respectively, X is an integer greater than 1, N 1, N 2,...N x are all integers greater than 1 and a sum Ntot of a total number of types of the downlink synchronization signals included in the X synchronization signal groups equals to N 1 +N 2 +......+N x; wherein the notifying, by the base station, the receiving end of configuration information related to the synchronization signal determined comprises: determining, by the base station, M physical broadcast channels; notifying, by the base station, the receiving end of the configuration information related to the synchronization signal determined through the M physical broadcast channels; wherein each of the M physical broadcast channels is bound to a respective one of Ntot types of the downlink synchronization signals, M is a positive integer less than or equal to Ntot; or the M physical broadcast channels are bound to part or all of the synchronization signals among the Ntot types of the downlink synchronization signals; wherein in the notifying, by the base station, the receiving end of the configuration information related to the synchronization signal determined through the M physical broadcast channels, at least one of the following information is notified, by the base station, to the receiving end through the M physical broadcast channels: resource allocation information about a synchronization signal group to which the synchronization signal bound to the physical broadcast channel belongs; resource allocation information about the X synchronization signal groups; an index of the synchronization signal group to which the synchronization signal bound to the physical broadcast channel belongs; an index of a resource group corresponding to the synchronization signal bound to the physical broadcast channel; and basic configuration information about the synchronization signal determined, wherein the basic configuration information comprises at least one parameter of a group consisting of: Ntot, N 1, N 2,...N x and X. determining, by a base station, the synchronization signal;
