Abstract
Embodiments of the present disclosure provide a signal synchronization method and apparatus for high frequency communication, and pertain to the field of wireless communications technologies. The method includes: performing, on a first beam pair, high frequency data communication with user equipment; if it is determined that the user equipment enters a dead zone state, sending a synchronization indication signal to the user equipment, where the synchronization indication signal includes at least quick synchronization indication information and user equipment information, and the user equipment information includes user ID information, beam ID information of a beam pair, and cell ID information; sending, on a specified high frequency resource, a synchronization signal to the user equipment. In the present disclosure, high frequency data communication is implemented by quickly performing re-synchronization in a dead zone state. Therefore, communication service quality is relatively high.
