CA 2409893
There is provided a transmission diversity system. In the case where an MS supporting a different antenna transmission diversity scheme enters the service area of a 4-antenna transmission diversity UTRAN, the UTRAN can transmit pilot signals and common data signals to the MS without the need of modifications to the MS. Therefore, power is distributed among antennas of the UTRAN and system capacity is increased.
Cette invention concerne un système d'émission de diversité. Au cas ou une station mobile utilisant un système d'antenne différent pour émission en diversité pénètre dans l'aire de service de l'UTRAN (Universal terrestrial Radio Access Network) à diversité d'émission à quatre antennes, l'UTRAN peut transmettre des signaux pilotes et des signaux de données communs à la station mobile sans qu'il faille apporter des modifications à cette dernière. La puissance est ainsi répartie entre les antennes de l'UTRAN et la capacité du système se trouve accrue.
