Abstract: This application provides methods and devices. An example method includes receiving measurement configuration information from a network device. The measurement configuration information includes a measurement object and a first measurement event associated with the measurement object. The measurement object is a carrier on which a first cell is located. Further, the first measurement event indicates a change of the first cell. The example method includes determining, based on a first measurement result of measuring the first cell on the carrier, that the first measurement event is triggered. The example method further includes, when the first measurement event is triggered, sending a measurement report to the network device, where the measurement report indicates that the first measurement event is triggered.
