A resource collaboration scheduling scheme in ultra-dense small cells

Ultra-dense network (UDN) is expected to be the main means of meeting the mobile traffic demands in 5G. Small cell is the main load of UDN to save energy and enhance coverage. However, the resource conflict become much more complicated than the conventional cellular system, because of the dense and random deployment and the dynamical switch of small cells, and the changeable users. Therefore, this paper proposes a resource collaboration scheduling scheme (RCS) in ultra-dense small cells. Simulation results show that proposed RCS scheme improves the network throughput and user satisfaction by dynamically allocating resources in ultra-dense small cells.
