METHOD, DEVICE, AND SYSTEM FOR COORDINATED ELIMINATION OF INTERFERENCE

摘要

A method, device, and system for coordinated elimination of an interference. The method comprises: a user equipment (UE) generates multidimensional codebook information on the basis of channel information; the UE estimates a residual interference to acquire a residual interference flag; and the UE transmits the multidimensional codebook information and the residual interference flag to a coordinative base station via a main base station, for use in instructing the coordinative base station to acquire a precoding matrix on the basis of the multidimensional codebook information and of the residual interference flag. The present invention solves the technical problem in the prior art that effective reduction of interference to an adjacent station UE is difficult due to difficulty in determining the size of the residual interference, and achieves the technical effects of effectively reduced interference to the adjacent station UE and of increased gain of coordinated multipoint transmission (CoMP).
