A method and apparatus for calibrating multiple access points are provided. The method includes: a cell receiving at least one parameter of at least one downlink channel fed back by a UE; according to the at least one parameter of the at least one downlink channel, calculating at least one parameter difference between at least one uplink channel and the at least one downlink channel; and according to the at least one parameter difference, calibrating multiple access points. The present invention can ensure desirable coherent transmission between access points so as to ensure system performance.
