A communication method includes a first communication apparatus that receives a measurement signal from a second communication apparatus. The first communication apparatus sends measurement evaluation information to the second communication apparatus. The measurement evaluation information indicates reliability of a measurement result due to a first cause or that the measurement result is unavailable due to the first cause. The measurement result is obtained based on the measurement signal. In this way, the first communication apparatus sends the measurement evaluation information to the second communication apparatus, where the measurement evaluation information indicates the reliability of the measurement result due to the first cause or indicates that the measurement result is unavailable due to the first cause.
