A PCI collision occurs between two intra-frequency cells that use an identical PCI. In this case, UEs in the overlapping area of the two cells cannot implement signal synchronization or decoding. Cleaning the PCIs is probably the most effective steps to improve RF performance. Good PCI assignment reduces call drops by enabling UE to clearly distinguish one cell from another
