LTE is designed for frequency reuse of one ? no frequency planning required ? Intersite interference coordination is possible by exchanging load information over X2 interface = soft frequency reuse ? Current simulations show no clear performance gains in downlink from intersite interference coordination ? Some performance potential in uplink by exchanging overload indicator information X2 X2 For internal use 31 169。 Nokia Siemens Networks Charles / 20220505 Res ou r c e b l oc k s 6 15 25 50 100S ub c arr i ers 72 180 300 600 1200M o du la t io n c o din g 1 . 4 M H z 3 .
