1. A communication method, wherein the method is used for cell selection, and the method comprises:
when a power class of a terminal device is a first power class, determining, by the terminal device, a first offset of the first power class and a second offset of the first power class;
determining, by the terminal device and based on the second offset and a smaller value between (1) a sum of the first offset and a maximum transmit power of the terminal device allowed by a first cell and (2) a maximum radio frequency output power that corresponds to the first power class and that is of the terminal device, a compensation amount of the first power class; and
determining, by the terminal device and based on the second offset and the compensation amount of the first power class, whether to camp on the first cell.
