  • Publication number: 20180270671
    Abstract: Disclosed embodiments pertain to PCI planning and selection. A base station may select a PCI value from available PCI values, where the selected PCI value may be associated with a PRS frequency that is different from PRS frequencies of neighboring base stations. For example, a base station may obtain neighbor Physical layer Cell Identity (PCI) values for neighboring cells of the base station, where each neighbor PCI value may correspond to a distinct neighbor cell of the base station. The base station may receive one or more available PCI values, and, determine, based on the available PCI values and the neighbor PCI values, whether the available PCI values comprise one or more available non-colliding PCI values. A non-colliding available PCI value may then be selected as the PCI value for the cell served by the base station when the available PCI values comprise one or more available non-colliding PCI values.
