Les interférences mutuelles entre les utilisateurs peuvent augmenter brusquement les interférences avec d'autres cellules et provoquer une situation de surcharge dans les systèmes WCDMA et HSDPA coexistants. La surcharge du trafic peut dégrader les performances des systèmes. Cette lettre propose un nouvel algorithme de contrôle dynamique de charge de liaison descendante (DDLC) pour réduire la dégradation des performances due à la surcharge dans la coexistence des systèmes WCDMA et HSDPA. Avec l'algorithme proposé, la charge de liaison descendante est contrôlée en fonction d'états de charge classés par deux seuils de contrôle de charge, et la surcharge de trafic est atténuée en ajustant dynamiquement les valeurs CQI signalées par les utilisateurs, sur la base de la charge de liaison descendante ainsi que des variations de canal. L'algorithme proposé est simulé et les résultats montrent que le schéma DDLC améliore les performances des systèmes WCDMA et HSDPA en termes de probabilité de panne, de débit total du système et d'utilisation des ressources radio.

Abstract: Mutual interference among users can abruptly increase othercell interference and cause overload situation in coexisting WCDMA and HSDPA systems. Traffic overloading can degrade the performance of the systems. This letter proposes a new dynamic downlink load control (DDLC) algorithm to reduce performance degradation due to overload in the coexistence of WCDMA and HSDPA systems. With the proposed algorithm, the downlink load is controlled according to load states classified by two load-control thresholds, and traffic overloading is alleviated by dynamically adjusting the CQI values reported by users, based on the downlink load as well as channel variations. The proposed algorithm is simulated and results show that the DDLC scheme improves the performance of both WCDMA and HSDPA systems in terms of outage probability, total system throughput, and radio resource utilization.
