Disclosed is a method for determining transmission power of a second TFCI bit indicating transport format information of data on a downlink shared channel transmitted from a selected Node B to a UE in a mobile communication system including the UE existing in a handover zone and a plurality of Node Bs in an active set of the UE. The Node Bs transmit dedicated channel data including a first TFCI bit to the UE over dedicated channels. A first Node B transmits dedicated channel data over a dedicated channel and transmits downlink shared channel data over the downlink shared channel. The first Node B determines a transmission power level of the second TFCI bit to be higher than a ratio of transmission power of the dedicated channel data from a Node B transmitting only the dedicated channel data to transmission power of the first TFCI bit.

L'invention concerne un procédé permettant de déterminer la puissance de transmission d'un second bit d'indicateur de combinaison de format de transport (TFCI) indiquant des informations de format de transport de données sur un canal partagé de liaison descendante (DSCH) transmises d'un noeud sélectionné B vers un équipement utilisateur (UE) d'un système de communications mobile comprenant l'équipement utilisateur existant dans une zone de transfert et une pluralité de noeuds B d'un ensemble actif d'UE. Les noeuds B transmettent des données de canal dédié comprenant un premier bit TFCI vers les UE sur des canaux dédiés. Un premier noeud B transmet des données de canal dédié sur un canal dédié, et transmet des données DSCH sur le canal DSCH. Ce noeud détermine que le niveau de puissance de transmission du second bit TFCI doit être supérieur au rapport entre la puissance de transmission des données de canal dédié provenant d'un noeud B transmettant uniquement lesdites données de canal dédié et la puissance de transmission du premier bit TFCI.
