L'interférence intercellulaire entre les liaisons montantes et les liaisons descendantes dans les systèmes de communication par paquets CDMA, employant un schéma TDD partagé, est évaluée dans des environnements cellulaires. Il s'avère que les interférences entre les stations de base dégradent rarement le débit de la liaison montante, mais que les interférences entre les stations mobiles dégradent considérablement le débit de la liaison descendante. Un schéma de contrôle de la puissance de transmission est proposé pour améliorer le débit de la liaison descendante. Le schéma proposé augmente la puissance de transmission des paquets de liaison descendante lorsqu'ils sont retransmis, et améliore ainsi le rapport signal/interférence des paquets de retransmission de liaison descendante. La simulation informatique montre que ce schéma augmente le débit de la liaison descendante sans sacrifier le débit de la liaison montante jusqu'à ce que le débit de la liaison montante atteigne une valeur maximale.

Abstract: The inter-cell interference between uplinks and downlinks in CDMA packet communication systems, employing a shared-TDD scheme, is evaluated under cellular environments. It is found that interference between base stations rarely degrades uplink throughput, but interference between mobile stations substantially degrades downlink throughput. A transmission power control scheme is proposed to improve the downlink throughput. The proposed scheme increases the transmission power of downlink packets when they are re-transmitted, and thus, improves the signal-to-interference ratio of the downlink re-transmission packets. Computer simulation shows that this scheme increases downlink throughput without sacrificing the uplink throughput until the uplink throughput reaches a maximum value.
