MICRO BASE STATION, MICRO BASE STATION INTERFERENCE COORDINATION METHOD, AND USER TERMINAL

摘要

The present invention relates to a micro base and a micro base station interference coordination method comprising: shifting, relative to subframes in the subframe configuration used in a macro base station, subframes in the subframe configuration used in the micro base station by several subframes, wherein the number of the shifted subframes causes subframes in the subframe configuration used in the micro base station which are corresponding to a specific channel in the subframe configuration used in the macro base station, not to transmit any signal un-allocatable by the micro base station after the shifting; emptying uplink subframes in the subframe configuration used in the micro base station after the shifting, which are corresponding to downlink subframes containing a designated channel in the subframe configuration used in the macro base station; and emptying the subframes in the subframe configuration used in the micro base station after the shifting which are corresponding to the specific channel in the subframe configuration used in the macro base station, or causing portions of the subframes corresponding to the specific channel not to transmit any signal.
