1. A method, comprising:
detecting, by a terminal device, a first synchronization signal block (SSB);
determining, by the terminal device, a second SSB based on the first SSB, wherein a frequency domain position of the first SSB and a frequency domain position of the second SSB are within a preset bandwidth, or a difference between frequency domain positions of the first SSB and the second SSB is a preset value, and both the first SSB and the second SSB are cell-defining synchronization signal blocks (CD-SSBs) that define a cell, and wherein information carried in a synchronization signal of the first SSB is the same as information carried in a synchronization signal of the second SSB, and information carried in a physical broadcast channel (PBCH) of the first SSB is the same as information carried in a PBCH of the second SSB; and
combining, by the terminal device, the PBCH of the first SSB and the PBCH of the second SSB to form a combined PBCH, and demodulating, by the terminal device, the combined PBCH.
