Abstract: Data characterizing a sector to assign a physical cell identifier (PCID) is received, the sector being associated with a base station in a communications network. A reuse distance for each of the PCIDs in the set of PCIDs presently available to the sector for assignment is determined based on a set of PCIDs presently available to the sector for assignment. The reuse distance is a distance between the sector and a nearest sector having the PCID. A PCID having a largest reuse distance of PCIDs having a physical layer identifier (ID) being different from a physical layer ID of at least another sector associated with the base station is selected based on the determined reuse distance for each PCID in the set of PCIDs presently available to the sector for assignment. The selected PCID is assigned to the sector. Related apparatus, systems, techniques, and articles are also described.
