Abstract
A system assigns PN offsets in a network (100) with multiple sectors (110). The system sets parameters for the network (100) and assigns PN offsets to the sectors (110) based on the set parameters. The system then identifies sectors (110) in the network (100) that have poor network performance as a result of the PN offset assignments. The system changes parameters for the identified sectors (110) and reassigns PN offsets to the sectors (110) based on the changed parameters to improve network performance.
