Abstract
A management node and method at the management node provide automatic PCI allocation to sites in a RAN by iteratively identifying a selected cell site to be allocated a PCI group. From a group of cell sites in the RAN that have already been allocated a PCI group, the method obtains, for each PCI group, a closest neighbor site having a least distance from the selected cell site. The method allocates a PCI associated with a closest neighbor site based on whether any of the closest neighbor sites meet criteria including, with respect to the selected cell site, a respective distance greater than a cluster distance, a lack of coverage overlap between any respective sectors, a tier relationship that is two or greater and a respective distance greater than an average cell footprint, and a lack of sectors that face any sectors of the given cell site.
