Disclosed is a channel allocation method in a CDMA communication system. The method comprises receiving from a UTRAN one SF node CSF,k out of 2m-1 SF nodes (where m is an integer larger than 3) arranged in the form of a tree having a mother node and child nodes; searching a group including the received SF node CSF,k; spreading a signal on a dedicated physical data channel (DPDCH) with an OVSF code corresponding to a selected one of the received SF node and its child nodes in the searched group; and spreading a signal on a dedicated physical control channel (DPCCH) with an OVSF code corresponding to an SF node based on the received SF node.
Cette invention se rapporte à un procédé d'atrribution de canal utilisé dans un système de communication CDMA, qui consiste à recevoir en provenance d'un réseau UTRAN un noeud SF (C¿SF,k?) parmi 2?m-1¿ noeuds SF (où m est égal à un nombre entier supérieur à 3) disposés selon une structure arborescente ayant un noeud mère et des noeuds progénitures; à rechercher un groupe contenant le noeud SF (C¿SF,k?) reçu; à diffuser un signal sur un canal de données physique spécialisé (DPDCH) avec un code OVSF correspondant à un noeud sélectionné parmi le noeud SF reçu et ses noeuds progénitures du groupe recherché; et à diffuser un signal sur un canal de commande physique spécialisé (DPCCH) avec un code OVSF correspondant à un noeud SF basé sur le noeud SF reçu.
