Abstract

Systems and methods for allocating a physical cell identifier (PCI) to a cell are described. In one implementation, the method comprises identifying allocated physical cell identifiers based on PCI data and generating a near PCI list and a far PCI list based on the allocated PCIs and a RSRP threshold value. Further, the method comprises determining cell group IDs and a cell IDs from the near PCI list and the far PCI list. Further, the method comprises assigning the cell group IDs to a first bin and the cell IDs to a second bin. Further, the method comprises prioritizing the cell group IDs in the first bin based on effective distance and the cell IDs in the second bin based on an effective RSRP value. Further, the method comprises allocating the PCI, to the cell, determined based on the prioritized cell group IDs and the cell IDs.
