Abstract
Embodiments of the present invention provide an information sending method, including: determining, by a base station, first information indicating a first carrier frequency offset, where the first carrier frequency offset is a carrier frequency offset between an actual cell carrier center frequency and a cell carrier center frequency that is obtained by a terminal; and sending, by the base station, the first information to the terminal, where the first information is used to obtain the actual cell carrier center frequency. According to the technical solutions provided in the embodiments of the present invention, quality of communication between the terminal and the base station is effectively improved.
