Abstract

The embodiment of the present invention discloses a method, a system and an apparatus for calibrating deviation among multiple access points, which are used for solving a problem that information received by a user equipment (UE) is not synchronous, caused when different access points send data to the UE at the same time, and improving system performance and frequency spectrum efficiency. The method for calibrating deviation among multiple access points comprises the following steps: in step A: a base station sending to a UE a message instructing the UE to perform measurement and return deviation calibration information among the multiple access points (S101); and in step B: the base station calibrating the deviation among the multiple access points based on the deviation calibration information among the multiple access points returned by the UE (S102).
