1. A method comprising:
receiving, by a relay node, synchronization signal information sent by a donor node of the relay node through an air interface, the relay node being configured to access a wireless communication network through the donor node, the synchronization signal information being configured for the relay node and enabling the relay node to generate a synchronization signal of the relay node, and the synchronization signal information comprising a physical cell identifier (PCI) of the relay node that is different from a PCI of the donor node, and the synchronization signal information further comprising a synchronization signal subcarrier spacing, information about an operating frequency band of the relay node, and a synchronization signal periodicity;
generating, by the relay node, a synchronization signal sequence based on the PCI of the relay node comprised in the synchronization signal information to generate the synchronization signal of the relay node; and
sending, by the relay node, the synchronization signal including the synchronization signal sequence that is generated.
