Cet article propose un algorithme de recherche rapide de cellules cibles utilisé lors d'une réception intermittente en mode veille d'une station mobile (MS) pour la radio mobile asynchrone W-CDMA intercellulaire. Dans le schéma proposé, étant donné que la station de base (BS) informe une MS des différences temporelles moyennes relatives reçues entre le code de brouillage de sa BS et ceux des BS environnantes en plus des codes de brouillage, la MS n'a qu'à rechercher dans le durée de synchronisation restreinte pour les codes de brouillage informés. Par conséquent, la recherche de cellules cibles (c'est-à-dire dans laquelle le nombre de cellules candidates est limité) peut être réalisée aussi rapidement que dans les systèmes synchrones intercellulaires. Une simulation informatique démontre que le temps de recherche de cellules cibles par supertrame (= 720 ms) avec une probabilité de détection de cellules de 95 % est réalisé en 5.9 ms (cela correspond au rapport de temps intermittent requis pour que la recherche de cellules cibles devienne 0.82 %. ), lorsque les rapports de puissance d'émission du canal pilote commun (CPICH) et du canal physique de commande commun (CCPCH) requis pour la recherche de cellules vers un canal de trafic dédié (DTCH) sont respectivement de 3 et 6 dB. Dans cette simulation, le profil de retard de puissance moyen a été généré en faisant la moyenne des profils instantanés (il s'agissait d'un signal pilote accumulé de manière cohérente sur une durée de 512 puces (= 125 µsec) à l'aide de 4 corrélateurs) sur une période de trois super trames pour 19 cellules cibles. sites candidats en utilisant la fenêtre de recherche avec une durée de 10 puces (= 2.4 µsec).

Abstract: This paper proposes a fast target cell search algorithm used during intermittent reception in the idle mode of a mobile station (MS) for inter-cell asynchronous W-CDMA mobile radio. In the proposed scheme, since the base station (BS) informs a MS of the relative average received timing differences between the scrambling code of its BS and those of the surrounding BSs in addition to the scrambling codes, the MS only has to search over the restricted timing duration for the informed scrambling codes. Therefore, the target cell search (i.e., in which the number of candidate cells is limited) can be achieved as fast as in inter-cell synchronous systems. A computer simulation demonstrates that the target cell search time per one super frame (= 720 msec) at the cell detection probability of 95% is accomplished within 5.9 msec (this corresponds to the intermittent time ratio required for the target cell search to become 0.82%), when the transmit power ratios of the common pilot channel (CPICH) and common control physical channel (CCPCH) required for cell search to a dedicated traffic channel (DTCH) are 3 and 6 dB, respectively. In this simulation, the average power delay profile was generated by averaging the instantaneous ones (it was coherently accumulated pilot signal over a 512-chip duration (= 125 µsec) using 4 correlators) over a period of three super frames for 19 target cell-site candidates using the search window with a 10-chip duration (= 2.4 µsec).
