Example measurement methods and apparatus are described. One example method includes receiving first information and second information from a network device by a terminal device. The terminal device determines a first resource based on the first information, and determines a second resource based on the second information. Further, the terminal device determines a third resource based on the first resource and the second resource, and performs measurement on the third resource. The third resource includes a part of or all resources in the first resource except a first overlapping resource, and the first overlapping resource is an overlapping resource of the first resource and the second resource.
