A Distance based Physical Cell ID Assignment for Self-Organizing LTE Femtocells

摘要: The femtocells, which are small base stations in cellular network, will be deployed randomly and large numbers; therefore, to integrate themselves the existing it requires them form a network distributed manner, i.e. self-organizing (SON). In this paper, we propose distance based physical cell ID (PCI) assignment scheme for LTE femtocells. Because of number femtocell stations, reusing PCI inevitable. Our algorithm minimizes used PCIs while removing collision confusion between neighbor cells. Simulation result shows minimization on our proposed scheme.
