Abstract

La présente invention suppose une situation dans laquelle un canal dédié de liaison montante amélioré (CDLMA) est utilisé dans un système daccès multiple à large bande par partage de code (W-CDMA). Dans un équipement dutilisateur, lorsque les canaux physiques de transmission des données du CDLMA sont transmis en plus des canaux physiques existants, un rapport de puissance crête/moyenne dun signal de transport montant augmente. Laugmentation du rapport de puissance crête/moyenne dépend des codes de facteur détalement variable orthogonal (OVSF) attribués aux canaux physiques correspondants et aux canaux en phase/en phase en quadrature (I/Q). Par conséquent, la présente invention propose un appareil et une méthode dattribution des codes OVSF et des canaux I/Q optimaux aux canaux physiques en lien avec le CDLMA afin de minimiser une augmentation du rapport de puissance crête/moyenne attribuable au CDLMA.
