Driven by the ever-increasing amount of mobile data, cellular networks evolve from small cell network to ultra-dense heterogeneous networks, to provide high system capacity and spectrum efficiency. Firstly, along with densification of small cells, inter-cell interference becomes severe and may deteriorate performance of mobile users. By bringing base stations (BSs) to the approximate spatial scale and number magnitude, ultra-dense heterogeneous networks would definitely bring unprecedented paradigm changes to the network design.
Secondly, the coverage area of BSs becomes small and irregular, resulting in much frequent and complicated handovers when mobile users move around. Assigning network resources including bandwidth and time slots, while avoiding interference, desires serious consideration. How to ensure continuous communication and implement effective mobility management, and
