INTERFERENCE COORDINATING METHOD, BASE STATION AND USER EQUIPMENT

摘要

A method of interference coordination, base station and user equipment. The method comprises: precoding by a macro cell eNB the signals of the downlink control channel of scheduled macro cell UE by using pre-obtained precoded matrixes, such that the signal null space formed by precoding is pointed to pico cells and/or the characteristic value space of the signals is pointed to the macro cell UE. With such a method, almost all the interference caused by the PDCCH of the macro cell to the pico cell is eliminated, and the performances of the macro cell are not affected, solving the problem existed in the prior art; or improving the receiving performance of the macro cell UE, and further alleviating the interference of the macro cell on the pico cells.
