INTERFERENCE COORDINATING METHOD, BASE STATION AND USER EQUIPMENT

摘要

An interference coordinating method, a macro base station and a User Equipment (UE) are disclosed in the present invention. The method includes the following steps: a macro base station performs pre-coding for the signal of the downlink control channel of the scheduled macro cell UE using a pre-coding matrix obtained before, so that the signal null space formed by pre-coding can be aimed to a pico cell, and/or the characteristic value space of the signal can be aimed to a macro cell UE. By the method, the interference for the pico cell caused by the Physical Downlink Control CHannel (PDCCH) of the macro cell almost can be eliminated, and the capability of the macro cell can not be influenced, so that the problem in the prior art can be solved; or the reception capability of the macro cell UE can be improved so that the interference for the pico cell caused by the macro cell can be reduced further.
