Method and system for allocating reuse codes to cells in a communication network

Abstract

Systems and methods for allocating reuse codes to cells in a communication network are described. In some embodiments, the systems and methods select a target cell from a group of cells in a telecommunication network, determine one or more reuse code exclusion zones associated with allocating scrambling codes to the selected target cell, and allocate a scrambling code to the selected target cell based on the determined one or more reuse code exclusion zones.

Background technique [0003] Wireless networks rely on a large number of individual base stations or cells to provide high-capacity wireless service over large coverage areas such as market areas (eg, cities), surrounding residential areas (eg, suburbs, counties), highway corridors, and rural areas. Continuous radio connectivity across these large coverage areas is achieved via user mobility from one base station to other base stations as users traverse the networ...

AI Technical Summary

Problems solved by technology

Often, reuse planning relies on RF path loss and inter-cell RF isolation estimates, which can be erroneous and misleading when compared to actual isolation between actual cells

Furthermore, reuse planning is often inadequate in allocating codes during network evolution and / or adding new cells into an established network, leading, among other drawbacks, to increased code reuse collisions over time and degraded network performance
