Abstract: This application provides a measurement method and an apparatus. In the measurement method, a communications apparatus may receive configuration information, where the configuration information includes a cell list and indication information, and the indication information is used to indicate whether a measurement event is affected by the cell list; and the communications apparatus performs a measurement evaluation based on the cell list and the indication information. In this implementation, whether to perform a trigger evaluation for a measurement result of a cell in the cell list may be determined depending on whether the measurement event is affected by the cell list, to avoid an unnecessary trigger evaluation for a cell.
