Abstract
A method includes receiving a transmission power, a distance from a source base station, and physical cell identifications (PCIs) under mod3 and mod30. The method includes determining a mod3 cost associated with allocating the PCI to the source base station based on the transmit power and the distance of the corresponding neighboring base station, and determining an overall mod3 cost as a summation of the mod3 costs of the neighboring base stations having the same PCI under mod3. The method also includes determining a mod30 cost associated with allocating the PCI to the source base based on the transmit power and the distance of the corresponding neighboring base station, and determining an overall mod30 cost as a summation of the mod30 costs of the neighboring base stations having the same PCI under mod30. The method further includes allocating the PCI having the minimum overall cost to the base station.
