METHOD FOR INTERFERENCE COORDINATION OF FEMTOCELLS, FEMTOCELL AND USER TERMINAL EQUIPMENT

摘要

The present invention proposes a femtocell interference coordination method, a femtocell and a user terminal equipment in a macro-femtocell deployment scenario. The key point of this invention is to stimulate a user terminal of the macrocell to initiate a random access request to a femtocell defined by a "closed subscriber group". Based on this, the femtocell will know there is a user that can not be detected by the macrocell and then trigger corresponding interference coordination operation to ensure that the user terminal equipment of the macrocell can at least receive information of control channels correctly.
