Les systèmes cellulaires d'aujourd'hui atteignent leurs limites en matière de débit de données en raison du nombre sans cesse croissant d'abonnés utilisant le service sans fil à des fins professionnelles ou pendant leurs loisirs (effet smartphone). Ainsi, des recherches récentes se concentrent sur les concepts de gestion des interférences pour les systèmes cellulaires OFDMA. Cet article aborde diverses techniques liées à ce sujet, tout en considérant les concepts les moins complexes et les moins coûteux comme candidats prometteurs à appliquer en premier. En commençant par les récepteurs anti-interférences sur MIMO multi-utilisateurs utilisant un précodage fixe jusqu'à l'estimation des interférences multi-cellules, qui améliore la précision de l'adaptation des liens, nous discutons de la formation de faisceaux de transmission coopérative en boucle fermée utilisant plusieurs stations de base regroupées dans un réseau distribué sans fil (WDN), qui est désignée comme transmission conjointe multipoint coordonnée dans la normalisation 3GPP LTE-Advanced. Il est évident que plus ces techniques sont sophistiquées, plus les demandes de feedback et de backhaul deviennent élevées. Les résultats de performances sont fournis en utilisant des simulations multicellulaires conformément aux recommandations du 3GPP. En outre, la faisabilité d'une transmission conjointe multipoint coordonnée est démontrée dans un prototype en temps réel, c'est-à-dire dans le banc d'essai LTE-Advance de Berlin.

Abstract: Todays cellular systems reach their limits for data rate due to the continuously increasing amount of subscribers using wireless service for business purposes or in leisure time (smartphone effect). Thus, recent research focuses on concepts for interference management for cellular OFDMA systems. This paper addresses various techniques related to this topic, while considering the concepts with lowest complexity and backhaul costs as promising candidates to be applied first. Starting from interference canceling receivers over multi-user MIMO using fixed precoding to multi-cell interference estimation, which improves the precision of link adaptation, we discuss closed-loop cooperative transmit beamforming using multiple base stations grouped into a wireless distributed network (WDN), which is denoted as coordinated multi-point joint transmission in the 3GPP LTE-Advanced standardization. It is obvious, the more sophisticated these techniques are, the higher the demands for feedback and backhaul become. Performance results are provided by employing multi-cell simulations according to recommendations from 3GPP. In addition, feasibility of coordinated multi-point joint transmission is demonstrated in a real-time prototype setup, i.e. in the Berlin LTE-Advance Testbed.
