Title:
METHOD AND APPARATUS FOR CONTROLLING INTER-CELLULAR INTERFERENCE IN HETNET SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/007445
Kind Code:
A1
Abstract:
Provided is a method and an apparatus for controlling inter-cellular interference in a heterogeneous network (HetNet) system, in which a macro cell and femto cells coexist. The apparatus for controlling inter-cellular interference overhears a control channel of the macro cell. The control apparatus determines an interference candidate resource, which is subject to inter-cell interference control, on the basis of the control channel. The control apparatus transmits an interference control message including information on the interference candidate resource.
