Systems and methods for effective physical cell identifier reuse

A system for allocating a physical cell identifier (PCI) to a cell in a wireless communication network, the system comprising:

• a processor operatively coupled to a memory device, wherein the processor is configured to execute instructions stored in the memory device to perform operations comprising:
• identifying allocated physical cell identifiers (PCIs) based on PCI data, the allocated Pas comprising near Pas and far PCIs;
• generating a near PCI list and a far PCI list-based on the allocated Pas and a reference signal received power (RSRP) threshold value;
• determining cell group IDs and cell IDs from the near PCI list and the far PCI list;
• assigning the cell group IDs to a first bin and the cell IDs to a second bin;
• prioritizing the cell group IDs in the first bin based on an effective distance between a near PCI and a far PCI, and the cell IDs in the second bin based on an effective RSRP value, wherein the effective distance between the near PCI and the far PCI is determined based on relative indices derived from the cell group IDs;
• assigning a final PCI to the cell, the final PCI being determined based on the prioritized cell group IDs and the cell IDs;
• determining maximum power transmit for the final PCI based on a power hysteresis between reused PCIs;
• and
• further determining the maximum power transmit for the final PCI based on a path loss and the power hysteresis.

A non-transitory, computer-readable medium storing instructions for allocating a physical cell identifier (PCI) to a cell in a wireless communication network that, when executed by a processor, cause the processor to perform operations comprising:

• identifying allocated physical cell identifiers (PCIs) based on PCI data, the allocated Pas comprising near Pas and far PCIs;
• generating a near PCI list and a far PCI list based on the allocated Pas and a reference signal received power (RSRP) threshold value;
• determining cell group IDs and cell IDs from the near PCI list and the far PCI list;
• assigning the cell group IDs to a first bin and the cell IDs to a second bin;
• prioritizing the cell group IDs in the first bin based on an effective distance between a near PCI and a far PCI, and the cell IDs in the second bin based on an effective RSRP value, wherein the effective distance between the near PCI and the far PCI is determined based on relative indices derived from the cell group IDs;
• assigning a final PCI to the cell, the final PCI being determined based on the prioritized cell group IDs and the cell IDs;
• determining maximum power transmit for the final PCI based on a power hysteresis between reused PCIs;
• and
• further determining the maximum power transmit for the final PCI based on a path loss and the power hysteresis.
