An interface between access points is enhanced by enabling an exchange of a cell characteristic information element (IE). The cell characteristic information can provide an access point with information about the characteristics/features/capabilities of its neighbor cells. Automatic neighbor relations are also enhanced to store and/or manage the cell characteristic information. Moreover, the cell characteristic information can be utilized by the access point to significantly improve handover (HO) decisions, increase load balancing performance, and/or decrease inter cell interference. The cell characteristic information can also improve network efficiency and avoid bottlenecks during cell reselection in Heterogeneous Networks (HetNets).
