Abstract: This present disclosure discloses example communication methods and communications apparatuses. One example communication method includes a terminal device determining a first offset of a first power class and a second offset of the first power class when a power class of the terminal device is the first power class. A compensation amount of the first power class is determined based on the first offset and the second offset. A determination as to whether to camp on a first cell is made based on the second offset and the compensation amount of the first power class.
