Patent

CA 2355305

The present invention relates to a method for downlink power control in the base station of a code division multiple access (CDMA) communication system. The total assigned downlink power from the base station is adjusted to a maximum downlink power level by means of individually adjusting the assigned bit rates of an appropriately selected subset of downlink channels to those users having a data communication connection. Said subset is retrieved by applying suitable selection criterions for the downlink channel, e.g., the momentarily assigned bit rate, the reported pathloss, or the user subscription type.

L'invention concerne un procédé de commande de puissance de liaison descendante dans la station de base d'un système de communication à accès multiple par répartition de code (AMRC). On règle la puissance totale attribuée à une liaison descendante à partir de la station de base à un niveau maximal par un réglage individuel du débit binaire (DB) attribué à un sous-groupe de voies descendantes sélectionné de manière approprié, à destination des utilisateurs disposant d'une connexion de transmission de données. Ce sous-groupe est déterminé par l'application de critères de sélection adéquats pour la voie descendante, p. ex. le débit binaire attribué temporairement, les pertes reportées pour une voie ou le type d'abonnement de l'utilisateur.
