An apparatus and method provides for controlling communications from multiple base stations to a mobile station in a communication system. A mobile station transmitter transmits from the mobile station channel quality indicator data of a first base station. The data is covered with Walsh code assigned to the first base station. A base station receiver receives the transmission of the channel quality indicator data of the first base station. The mobile station transmitter punctures the transmission of the channel quality indicator data of the first base station with null channel quality indicator data, and covers the null channel quality data with Walsh code assigned to a second base station of the multiple base stations to indicate a desire to switch a source of transmission of traffic data from the first base station to the second base station.

L'invention concerne un appareil et un procédé destinés à commander des communications entre plusieurs stations de base et une station mobile dans un système de communication. Un émetteur de station mobile émet à partir du canal de station mobile des données indicatrices de qualité d'une première station de base. Ces données sont protégées par un code de Walsh attribué à la première station de base. Un récepteur de station de base reçoit l'émission de données indicatrices de qualité du canal de la première station de base. L'émetteur de station mobile réalise l'émission des données indicatrices de qualité du canal de la première station de base au moyen de données indicatrices de qualité du canal nul, et protège ces données de qualité de canal nul au moyen d'un code de Walsh attribué à une seconde station de base parmi les multiples stations de base afin d'indiquer la volonté de commuter une source d'émission de données de trafic entre la première station de base et la seconde.
