This application provides a communication method and an apparatus. The method includes: receiving, by a terminal apparatus, first information from a second base station, where the first information includes network-based cell-specific reference signal CRS bandwidth mitigation status information of a first base station, the second base station is a base station of a serving cell of the terminal apparatus, and the first base station is a base station of a neighboring cell of the serving cell; determining, by the terminal apparatus, a measurement bandwidth value based on at least the first information; and measuring, by the terminal apparatus based on the measurement bandwidth value, at least one of signal strength or signal quality of the serving cell in which the terminal apparatus is located or the neighboring cell of the serving cell.
