5G Ultra-Dense Networks In future 5G networks,a key scenario is the dense user distribution over some area,such as office,urban apartments,shopping mall,stadium,etc.,where the requirement for user-experienced rate at cell-edge can be as high as 1 Gbps.Such requirement calls for heterogeneous topology of cells comprised of macro nodes and various types of low power nodes(LPN)to improve the system capacity.
