Les structures femtocellulaires peuvent offrir un meilleur échange de voix et de données dans les réseaux cellulaires. Cependant, les interférences dans de tels réseaux posent un défi majeur au développement pratique des communications cellulaires. Pour résoudre ce problème, un schéma avancé d'atténuation des interférences pour les réseaux femtocellulaires à visibilité directe (LOS) dans les environnements intérieurs est proposé dans cet article. À l'aide d'un système de gestion de femtocellules (FMS) qui contrôle toutes les femtocellules dans une zone de service, les femtocellules agressives sont identifiées, puis les diagrammes de faisceaux transmis sont ajustés à l'aide de l'antenne réseau linéaire équipée dans chaque femtocellule pour atténuer la contribution d'interférence aux femtocellules voisines. Avant cela, les utilisateurs concernés sont commutés vers les femtocellules qui offrent de meilleurs niveaux de débit pour éviter d'augmenter la probabilité de panne. Cet article considère différents indices de déploiement de femtocellules pour vérifier et justifier la faisabilité des résultats dans différentes zones de densité. Par rapport aux schémas de contrôle de puissance fixes et adaptatifs, le schéma proposé permet d'obtenir une amélioration d'environ 5 % de l'efficacité spectrale (SE), une réduction d'environ 10 % de la probabilité de panne et une amélioration moyenne du débit utilisateur d'environ 7 % Mbps.

Abstract: Femtocell structures can offer better voice and data exchange in cellular networks. However, interference in such networks poses a major challenge in the practical development of cellular communication. To tackle this issue, an advanced interference mitigation scheme for Line-Of-Sight (LOS) femtocell networks in indoor environments is proposed in this paper. Using a femtocell management system (FMS) that controls all femtocells in a service area, the aggressor femtocells are identified and then the transmitted beam patterns are adjusted using the linear array antenna equipped in each femtocell to mitigate the interference contribution to the neighbouring femtocells. Prior to that, the affected users are switched to the femtocells that provide better throughput levels to avoid increasing the outage probability. This paper considers different femtocell deployment indexes to verify and justifies the feasibility of the findings in different density areas. Relative to fixed and adaptive power control schemes, the proposed scheme achieves approximately 5% spectral efficiency (SE) improvement, about 10% outage probability reduction, and about 7% Mbps average user throughput improvement.
