1. A method for detecting a synchronization signal, the method comprising:
determining, by a terminal, a numerology for detecting the synchronization signal; and
detecting, by the terminal, the synchronization signal according to the determined numerology;
wherein after the terminal detects the synchronization signal according to the determined numerology, the method further comprises:
method 1: determining, by the terminal, a Transmission and Reception Point (TRP) group to which the terminal belongs according to the detected synchronization signal; or
method 2: determining, by the terminal, a TRP for the terminal to reside in or access, according to a correspondence relationship between the detected synchronizations signal and a TRP;
wherein the method 1 and the method 2 comprise:
selecting, by the terminal, a synchronization signal with a highest signal strength from detected synchronization signals; and
determining, by the terminal, a TRP group Identity (ID) corresponding to the selected synchronization signal according to a correspondence relationship between a synchronization signal and a TRP group ID.
