A channel correction method, used for performing channel correction on radio frequency apparatuses in a network area, is provided. The radio frequency apparatuses are divided into at least one radio frequency apparatus group. A correction resource location is set for each radio frequency apparatus in the radio frequency apparatus group. These resource locations may be stored in a form of configuration information in base stations where the radio frequency apparatuses are located, so that the base station controls each of these radio frequency apparatuses to send a correction signal in a respective correction resource location based on the configuration information, and to implement, by using these correction signals, channel correction for the radio frequency apparatuses in the radio frequency apparatus group. The method can implement joint channel correction for a plurality of radio frequency apparatuses and improve correction efficiency.
