Claim:
1. A method for calibrating deviation among multiple access points, comprising: in step A: a base station sending to a user equipment (UE) a message instructing the UE to perform measurement and return deviation calibration information among the multiple access points; and in step B: the base station calibrating deviation among the multiple access points based on the deviation calibration information among the multiple access points returned by the UE; wherein the deviation calibration information comprises at least one of a delay inequality, a phase calibration information and an amplitude calibration information, the delay inequality comprises a channel delay inequality and a timing synchronization deviation; wherein the step A comprises: the base station sending to the UE a message instructing the UE to measure the delay inequality among the multiple access points and instructing the UE to return the delay inequality; and wherein the step B comprises: the base station calibrating the delay inequality among the multiple access points based on the delay inequality among the multiple access points returned by the UE.
