1. A communications method, comprising:
determining a first physical cell identifier (PCI) of a first synchronization signal and physical broadcast channel (PBCH) block (SSB) and a second PCI of a second synchronization signal and PBCH block (SSB);
determining that the first PCI of a first cell conflicts with the second PCI of a second cell; and
sending, by a first access network device, indication information to a second access network device, wherein the indication information is used to indicate that the first PCI conflicts with the second PCI.
