Cet article étudie l'effet de la sélection rapide de cellules (FCS) associée aux méthodes de planification rapide des paquets et à la demande de répétition automatique hybride (HARQ) avec combinaison Chase, dans laquelle la cellule (ou secteur) optimale transmettant un canal partagé de liaison descendante attribué par créneau (DSCH) est sélectionné sur la base du rapport signal/puissance d'interférence (SIR) reçu, dans le cadre d'un accès par paquets de liaison descendante à grande vitesse (HSDPA). Les planificateurs Round Robin (RR), Proportional Fairness (PF) et Maximum Carrier-to-Interference Power Ratio (CIR) sont utilisés comme algorithme de planification. Les résultats de la simulation montrent que même si presque aucun gain de diversité supplémentaire via FCS n'est obtenu pour les ordonnanceurs PF et Maximum CIR, l'amélioration du débit par FCS couplée à l'ordonnanceur RR est obtenue. De plus, nous expliquons que l’effet du FCS est faible lorsque seul le FCS intersectoriel est effectué ; cependant, le FCS intercellulaire est efficace pour améliorer le débit de la liaison radio pour les utilisateurs d'accès avec un SIR reçu inférieur près du bord de la cellule. Le débit de la liaison radio pour la distribution cumulée de 20 % des utilisateurs de transfert progressif lorsque les FCS intersectoriels et intercellulaires sont effectués est augmenté d'environ 20 % et 60 % pour les ordonnanceurs PF et RR, respectivement, par rapport à celui sans FCS, c'est-à-dire avec un transfert dur. Nous montrons également que lorsqu'un modèle de trafic tel que le modèle de navigation ETSI WWW modifié est pris en compte, l'effet du FCS associé à l'effet décroissant de la planification rapide des paquets est supérieur à celui supposant une transmission continue des paquets. Le débit utilisateur avec une distribution cumulée de 20 % employant à la fois un FCS intersectoriel et intercellulaire est augmenté d'environ 60 % par rapport à celui sans FCS.

Abstract: This paper investigates the effect of fast cell selection (FCS) associated with fast packet scheduling methods and hybrid automatic repeat request (HARQ) with Chase combining, in which the optimum cell (or sector) transmitting a slot-assigned downlink shared channel (DSCH) is selected based on the received signal-to-interference power ratio (SIR), in high-speed downlink packet access (HSDPA). The Round robin (RR), Proportional fairness (PF) and Maximum carrier-to-interference power ratio (CIR) schedulers are used as the scheduling algorithm. The simulation results elucidate that although almost no additional diversity gain through FCS is obtained for the PF and Maximum CIR schedulers, the improvement in throughput by FCS coupled with the RR scheduler is achieved. Furthermore, we elucidate that the effect of FCS is small when only inter-sector FCS is performed; however, inter-cell FCS is effective in improving the radio link throughput for the access users with a lower received SIR near the cell edge. The radio link throughput at the cumulative distribution of 20% of soft handover users when both inter-sector and inter-cell FCS are performed is increased by approximately 20% and 60% for PF and RR schedulers, respectively, compared to that without FCS, i.e. with hard handover. We also show that when a traffic model such as the modified ETSI WWW browsing model is taken into account, the effect of FCS associated with the decreasing effect of fast packet scheduling is greater than that assuming continuous packet transmission. The user throughput at the cumulative distribution of 20% employing both inter-sector and inter-cell FCS is increased by approximately 60% compared to that without FCS.
