• The physical cell ID (PCI) is used to indicate the physical layer identity of the cell. The PCI is used for cell identity during cell selection procedure. The purpose of PCI optimization is to ensure to a great extent that neighboring cells should have different primary sequences allocated. 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. The PCI planning proposal for a LTE network deployment includes each site shall have unique physical layer cell identity group, ranging from [0 to 167] and each sector within a site shall have unique physical layer sub‐cell identity, ranging from [0 to 2]. Usually, the proposed PCI percentage planned for in‐building is 30% and outdoor cells is 70% of all available PCI.
