One example method includes that a terminal device receives first information and second information. The first information indicates a time domain position of an SSB sent by a serving cell, and the second information indicates a set of SSBs that the terminal device needs to measure and that are sent by a neighboring cell. The terminal device measures, in a first measurement window based on the first information, the SSB sent by the serving cell. The terminal device measures, in a second measurement window based on the second information, the SSB sent by the neighboring cell. ## Claims ### Claim 1 A synchronization signal/physical broadcast channel block (SSB) measurement method, comprising: receiving, by a terminal device, first information, wherein the first information indicates a time domain position of an SSB sent by a serving cell;
